Sooner or later you have to change your interior doors. The procedure is not so complicated that it is necessary to hire a specialist. If you have at least some skills in handling a saw, a level and a plumb line, you can tighten a few self-tapping screws - you can do it yourself. When replacing, before installing interior door, the old one needs to be dismantled. And here too there are peculiarities. About all the subtleties - in photos and videos with detailed instructions.

Interior doors are made from different materials. Moreover, the material and door leaf and frames. The door leaf is:

• From fiberboard. These are the cheapest doors. Represent wooden frame, to which the laminated fiberboard is attached. They have low sound insulation, they are afraid high humidity, are easily damaged.
• From MDF. They cost much more, but also quality characteristics much higher. They have better sound insulation, are not afraid of moisture, are stronger and more durable.
• Wood. The most expensive doors. Made from different varieties wood - from pine to oak or more exotic species.

Door frames are also made from the same materials. The worst choice is that fiberboard boxes bend even under their own weight, and hanging the door leaf on them is a real pain. So try to take either MDF or wood. There is another material: laminated wood. It is good because it does not need to be processed or painted, but the service life depends on the quality of the film.

Dimensions and equipment

Interior doors are produced in standard sizes, it’s a pity that the standards are different countries are different. For example, in our country, swing doors are made 600 - 900 mm wide with a pitch of 100 mm. In some EU countries the rules are the same - in Germany, Italy and Spain. In France, others are standard. Here the narrowest doors are 690 mm and then in increments of 100 mm.

Is the difference really that important? If you want to change only the door leaf without the frame, then it is important - you will have to choose from your segment or completely change it along with the frame. There is a much greater choice of interior doors of the same standard as in our country, while in France there is much less choice.

What width of doors you need depends on where you are going to place them. If we talk about standards, the following values ​​are recommended:

• V living room width from 60 to 120 cm, height 2 m;
• bathroom - width from 60 cm, height 1.9-2 m;
• in the kitchen, the width of the door leaf is at least 70 cm, height 2 m.

If, when replacing a door, it is decided to make the opening larger/smaller, permission is not required for this, but it is necessary to remain within the limits specified for each room.

How to determine what width of doors to buy? Measure the door leaf you have and you will know what you need. If there are no doors, find the narrowest place in the opening, measuring it, you can find out how wide you need door block. This is a door leaf + door frame. So the outer dimensions of the door frame should be less than the measured value. For example, you got 780 mm, look for a block with parameters of 700 mm. Wider ones cannot be inserted into this opening.

The most complete set of interior doors - with frame, extensions and trims

When choosing a door, pay attention to the equipment. There are three types of assembly:

• Door leaf. You buy the box separately.
• Doors with frame. Everything is included, but the box is in the form of separate boards. You will have to file the corners and connect, hang the hinges yourself.
• Door block. These are ready-to-install doors - the frame is assembled, the hinges are hung. Just cut the sidewalls to the height, align them evenly and secure them.

Even though the quality of the door leaf is the same, the prices for these kits differ significantly. But the difference in the time you spend on installation is significant.

Step-by-step installation of interior doors

In general, there are many subtleties. We will try to describe and illustrate the most common moments in photo or video material.

Step 1: Assembling the Door Frame

If you did not buy the door block assembled, the first thing you will have to do is assemble door frame. It consists of two long posts located on the sides, and one shorter crossbar at the top - the lintel.

Connection methods

There are at least two options for how to connect these planks to each other:

Regardless of exactly how you plan to connect the elements of the door frame, the first step is to cut down the pillars and lintels on one side. Then they are placed in a box on the floor, checking the correct connection. Next, you need to decide on the height of the side parts of the door frame.

Determining the dimensions

When folded, the required length is measured along the inside of the rack. The racks are not always made the same: the floor is often uneven and this must be taken into account. To do this, take a level and check how level the floor is. If it is perfectly level, the posts will be the same. If there is a deviation, it must be taken into account: make one of the racks longer. Usually this is a few millimeters, but this is also enough for the doors to warp.

When calculating the height, keep in mind that the racks should be 1-2 cm longer than the door leaf (including cuts). Make a 1 cm gap under the door if you are not planning to put a rug under it. If there is a rug/carpet/carpet, it is better to make it larger. Don't be afraid to leave gaps. They are necessary for. Please note once again: the height is measured along the inside of the door frame - from the bottom edge to the cut. Having cut it off, try on the racks in the doorway.

Now you need to saw off the lintel to length and, if necessary, saw on the other side (if the joint is at 45°). The length of the lintel should be such that when folded, the distance between the posts is greater than the width of the door leaf. The minimum gap is 7 mm, but more is often done. 7-8 mm are distributed as follows: 2 mm for hinges, and 2.5-3 mm for expansion gaps. Any interior doors - MDF, fiberboard, wood - change their dimensions depending on humidity. To accommodate these changes, clearances are required. And 5-6 mm is not always enough, especially in damp rooms. For the bathroom, definitely leave a little more, otherwise in high humidity they may have difficulty opening.

So, we decided on minimal gaps when installing interior doors:

• for hinges - 5-6 mm;
• at the top, bottom and sides - 3 mm;
• bottom - 1-2 cm.

After you have cut all the pieces and made the cuts, fold the box on the floor. If you notice any shortcomings in the joint, correct them using sandpaper attached to a block. The more accurate the match, the smaller the gap.

Assembly

Regardless of the material of the box and the connection method, holes are pre-drilled for the fasteners so that the material does not tear. The diameter of the drill is 1 mm less than the diameter of the screw.

The box is folded and the angles are set to 90°. Holding the stand and lintel in this position, drill holes with a drill. If there is an assistant, he can hold it. If you are working alone, temporarily secure the correctly aligned box with two cross bars - closer to the top and one at the bottom. This will help you avoid mistakes and make the correct connection.

If connected at an angle of 45°, make three holes on each side. Two on top - a centimeter away from the edge, and one on the side - in the center. In total, three screws are required for each connection. The direction of installation of self-tapping screws is perpendicular to the connection line.

If you connected at 90°, everything is simpler. Drill two holes from above, pointing the drill straight down.

Step 2: Inserting the hinges

Most often, 2 hinges are installed on interior doors, but 3 are possible. They are placed 200-250 mm away from the edge of the door leaf. If the frame and door leaf are made of wood, choose a place so that there are no knots. First, attach the hinges to the door leaf. The operating procedure is as follows:

• We apply loops to the selected places and outline the contours. The easiest way to do this is with a finely sharpened pencil, but experts advise using a knife blade. This makes it more accurate and leaves smaller gaps.
• If they have it, if not, take a chisel and select a material for the thickness of the loop. There is no need to make any more sampling, just for the thickness of the metal.
• A loop is installed in the prepared recess. Its plane should be flush with the surface of the canvas.
• The exposed loop is fixed with self-tapping screws.

Having secured the two hinges, place the door leaf in the assembled frame, set the correct gaps: on the side of the hinges - 5-6 mm, 3 mm on the opposite side and on top. Having set these gaps, the canvas is fixed using wedges. Place it exactly in the horizontal and vertical plane (you can use pads if necessary).

After setting, mark the locations of the mating parts of the loops. Sometimes it is more convenient to remove an already installed hinge and then install it in place. A notch is also made according to the markings. Depth - so that the surface of the hinge is flush with the surface of the door frame.

DIY door hanging is described in detail in the video.

Step 3: Installing the Door Frame

The assembled box must be correctly inserted into the opening. This is a very responsible task. Before installing an interior door, knock down everything in the opening that could fall off. If the wall is too loose, the surface is treated with primers deep penetration with an astringent effect. If there are too large holes, they are sealed with plaster; very large protrusions are trimmed off. It is easier to insert an interior door into the prepared opening. If this is your first time doing this on your own, make it easier on yourself.

The box is displayed without the door leaf. It is oriented strictly vertically. Verticality is checked not only by level, but also by plumb line. The level often gives an error, so it is more reliable to check with a plumb line.

To prevent the box from becoming warped during installation, install temporary spacers on the floor and bevels in the corners which give a high degree of rigidity. In order for the doors to open, they are inserted in the same plane with the wall. This is the only way it will open completely. If the wall is uneven, place the box not along the wall, but vertically. Otherwise there will be problems with opening or closing the door.

How to insert an interior door with your own hands - in the same plane as the wall

Once the position is selected, you can secure it. This is done using mounting wedges - triangular wooden or plastic bars. First, wedges are placed on both sides of the lintel - crossbars, then above the racks. In this way, the position of the box relative to the doorway is selected and fixed. Next, the verticality of the racks is checked again. They are checked in two planes so that they are not tilted forward or backward.

Then install the wedges at the bottom, then after about 50-60 cm, checking that the racks are exactly level. The crossbar is also wedged in the middle. Check whether the elements of the box are bent somewhere, and correct if necessary. You can start fastening.

Step 4: Attaching the Box to the Doorway

There are also two mounting methods: through directly to the wall and with mounting plates. If the wall allows and you are not afraid of the fastener caps in the box, you can attach it all the way through. It's reliable.

To install interior doors, it is enough to screw two self-tapping screws into the cutouts for the hinges and, on the other hand, under the plate of the lock mate. Additional holes are drilled in the cutouts. They are made so as not to fall into the holes for fastening the hinges or mating part. Make sure that the head of the screws is recessed and does not interfere with the installation of the hinges and lining.

Installation of interior doors according to this diagram is shown in the video. There are also several interesting nuances regarding the placement of the door frame.

If such a quantity of fasteners seems unreliable, drill through and cover the holes with decorative washers matched to match. Or there is also a special molding made of MDF with removable slats. The fastener is installed in the prepared groove and then closed with a strip.

The second method is secret, the fasteners are not visible. First attach from the back of the box mounting plates. In principle, it can be used for plasterboard, but there are also special ones that are thicker, although when installing interior doors, plasterboard ones will suffice.

Step 5: Foaming

After all the gaps are set and the wedges are installed, the gaps between the frame and the wall are filled polyurethane foam. For better polymerization, the wall is moistened with water from a spray bottle. Then squeeze out the foam, filling no more than 2/3. Too much a large number of foam may cause the box to blow inward. So don't overdo it.

To ensure that the doors are not warped by the foam, spacers are installed. But if you don't overdo it with foam, nothing should happen.

Spacers for fixing the frame - when installing the interior door this way, the frame should stand level

After the foam has polymerized (the exact time is indicated on the cylinder), the spacers are removed, the door leaf is hung and the operation of the door is checked. Next come Finishing work: and platbands, if necessary - additions.

You know how to install an interior door with your own hands. There is nothing overly complicated, but we tried to describe the main nuances. There is a lot of useful information in the video - these are recommendations from practitioners.

Replacing interior doors is not as labor-intensive and complicated a process as it seems. You can fill a double or single opening yourself without the help of a specialist. Of course, you won’t save time, but you will save money and acquire new skills when renovating an apartment or house.

How to install an interior door: in this article we will tell you how to choose a good door leaf, what the block for filling the opening is made of and how to install it.

Opening measurement

Making a mistake at the stage of measuring the doorway is unacceptable: if you purchase a system of large dimensions, you will not be able to insert it, and if you purchase a smaller one, you will not be able to fix it well.

It is better to measure the doorway after dismantling old door when access to the bare wall became available. This way you can assess the situation and make correct measurements. Removing them is simple: take a tape measure and determine the height and width of the entrance along the wall in the very bottleneck(relevant for buildings where the vertical structure of the structures is poorly observed). With this data, go to the store for a new door.

Manufacture of the product according to custom sizes not required: in houses with apartments, builders initially lay out standard openings, and fillings for them are always available for open sale.

Interior doors in private wooden house may differ from the standard ones, then you will have to order new ones and wait for their production.

Door selection

The first thing you should pay attention to when choosing canvas and boxes is the material they are made of.

The ideal option is to purchase a box and canvas made of the same material. You should not give preference to wood fiber board; doors made from it are short-lived; they are installed on construction sites so that new owners can replace them with permanent ones made of more durable materials. Ideally, it is worth acquiring a solid solid wood as a door filling; to reduce the cost, the canvas can be replaced with MDF, which is also a durable raw material for the manufacture of a cheaper door frame.

Additional strips and trims can be made of fiberboard, wood or MDF. They do not carry a load, they only decorate gaps and disguise connections.

Double doors are often chosen for large rooms and halls, single-leaf blocks are installed in bedrooms and kitchens. In any case, the size of the box and the number of panels are determined by the size of the opening.

Step-by-step instructions for installing from scratch

Installing interior doors with your own hands will not take much time, just stock up the right tool, purchase required material and you can start working. Follow detailed step-by-step instructions and your success is guaranteed.

This plan is valid for installation swing doors, sliding ones are mounted slightly differently, but in a similar way.

Step 1: prepare tools and material

To install an interior door you will need:

1. Drill or hammer drill;
2. 3 and 4 mm drills for wood;
3. Drills 4 and 6 mm for concrete;
4. Saw;
5. Screwdriver;
6. Wood screws;
7. Level/plumb;
8. Polyurethane foam;
9. Roulette;
10. Pencil.

In addition, a door block must be purchased in advance.

Step 2: determine action tactics

Installation of wooden doors is carried out according to the standard scheme shown in the photo.

1. Door frame;
2. Door leaf;
3. Nail/screw;
4. Polyurethane foam.

First, we assemble the box, then insert it into the opening and hang the door.

Step 3: assemble the box

There are 2 options for assembling the box under the canvas.

To understand whether the excess parts of the wood have been cut correctly, assemble the box on the floor like a mosaic: everything should fit together perfectly. Then we fix the planks with self-tapping screws on the side of the wall.

For the threshold, you also need to determine the place by attaching the canvas to the box assembled along the top. Step back 2.5 mm from it and make a risk. Attach the bottom bar - the threshold - to this mark.

Step 4: marking for hinges

At the stage of assembling the box, it is worth determining the places where the hinges are attached. To do this, measure 20-25 cm from the top and bottom on the side stand, attach loops and make marks with a knife or pencil. Screw the product with self-tapping screws, thereby determining the future location of the loop, which will facilitate its fastening. Now insert the canvas, measure the gaps to the side edges and make marks on the canvas. In the same way, make several fasteners so as not to lose their location later.

Remove the screws and the hinge; they will need to be fastened after installing the box in the opening.

The box is ready for installation. More detailed process demonstrates the author of the video.

Step 5: Installing the Box

Now it’s time to install the doors yourself, and it starts with installation assembled box. To do this, you need to place the structure on the threshold and align the vertical. For verification, use a plumb line and level. To prevent the box from falling during verification, secure it with spacers or temporary wedges made from scraps of wood.

Now you can check the canvas: will it open or not. To do this, you need to insert it into the installed box, focusing on a flat wall. If opening does not occur or is not fully realized, it may be necessary to adjust the spacers and adjust the position of the rack and cross bars.

If you managed to install everything correctly and the canvas fits well into place, you can fasten the box. How to do it:

1. Wedges are driven in on the sides of the upper cross member, then above where it is attached to the racks;
2. Drive wedges along the entire height of the opening, constantly checking the evenness of the installation and the absence of displacements in any plane.

Step 6: secure fit

The delivered and verified box must be finally secured so that it can accept the canvas. There are 2 solutions:

1. Screw the box to the side walls with screws. This reliable way, to implement it, a few wood screws or self-tapping screws are enough. Choose inconspicuous places for fastening; they mainly use areas under door hinges and under the lock plate. They take a concrete block and make a hole for a screw. Now tighten the fastener so that its head does not remain above the plane of the wood. If this amount of fasteners is not enough, you can drill through holes in other places and also install self-tapping screws, the heads of which are covered with plugs to match the surface.
2. The second method is to use hidden plates. The peculiarity of the method is that there is no need to drill the frame and wall.

After this, fill the space between the opening and the box with mounting foam to 2/3 of the total thickness. To prevent the structure from being squeezed out, install spacers inside the passage contour while the foam polymerizes.

Step 7: attach the hinges

When installing interior doors correctly, the hinges are attached only before directly hanging the door leaf. Screw the parts for the box to the previously marked places, repeat the steps for the canvas.

Step 8: hanging and cladding

The hardest part is over, now you can hang the canvas and cover the joints with platbands. The master clearly explains in the video how to install an interior door.

As you can see, it is quite possible to replace or install a new interior door yourself, following a clear procedure. The technology is described in detail and shown in the accompanying videos, so understanding the issue will not be difficult.

The ability to handle carpentry and measuring tools is already a reason to try to solve such a difficult task as installing interior doors with your own hands. The work is simple, but tricky in its own way. It will take scrupulousness and even tediousness in marking and adjusting, otherwise it will not be possible to install the interior door with the frame correctly.

Features of installing interior doors

At first glance, nothing complicated, but this is only a superficial impression. We are talking about not just installing the frame and door leaf into the interior opening, but doing it beautifully, without distortions, scratches or sagging hinges. If this is your first experience, then it is best to make a detailed step by step instructions DIY installation of interior doors. This is not shameful for beginners. Even experienced craftsmen often make notes with their own hands - what not to forget and what to pay attention to when installing a door frame on a specific interior partition.

During the installation process, you will need to solve two of the most difficult problems yourself:

• Correctly assemble and install the frame of interior doors, align and secure it so that the frame does not sag under the weight of the door leaf;
• With your own hands, mark and cut out the mounting grooves on vertical rack boxes and at the end of the interior door leaf.

It takes an experienced craftsman 2-3 hours to install an interior door; a beginner will need at least a day to completely install the frame and hang the door leaf.

Advice! It is not necessary to stupidly follow the instructions for installing interior doors, which recommend sequentially installing lock fittings, attaching hinges, and only at the very end solving problems with hanging interior doors. The main thing is to install the frame and door leaf with your own hands with a fresh mind, and you can put off the trim, locks and handles with trim for the next day.

There will be a lot of measuring and sawing. All cuts are made by hand hand hacksaw, therefore, in addition to fresh forces, you will need to stock up on quality tools.

Tools for installing interior doors

A day or two before the start of work, you will need to assemble a working arsenal for working with lumber. You can collect it from friends or rent it. Why two days before installation? Because well before starting work, you will need to check with your own hands the serviceability and functionality of each tool:

• Construction levels - small, 70-100 cm, and large, 150 - 200 cm, with a working bubble indicator. Usually they don’t pay attention to the condition of the camera and beacon, considering them to be in good working order, but at rental stores you can sometimes find bent and even broken copies, these are the most important tool in the installation of interior doors;
• Marking tool - carpenter's corner with a ruler, tape measure and meter metal ruler. We check for the presence of angle marks at 90° and 45°;
• A screwdriver or electric drill with a bit attachment for cross-head screws. We check with our own hands how the cartridge holds, and the serviceability of the wiring - batteries;
• Cutting tool, you can cut the timber of interior doors with a jigsaw, but it is best to stock up on a pair of hacksaws - carpentry and metal. The first is used for cutting box parts, the second is used for fine cutting of platbands.

In addition to the tool, you will need a hammer, a clamp, a carpenter's chisel, foam in a can, tape and gloves. There is little dust and waste generated when installing interior doors, but you will still have to periodically remove it with your own hands so as not to spread it throughout the apartment.

In addition, it would be correct to have a hammer drill with a bayonet blade in stock, because when installing an interior door frame, problems may occur with the doorway in the wall. Ideally, the gap between the frame posts and the ends of the opening should remain 10-20 mm, for normal alignment and foaming of the cracks. In reality, the opening may be uneven, and you will need to knock down part of the concrete or stone with your own hands, a hammer drill or a hammer and chisel.

How to assemble an interior door frame

The best option would be to purchase a ready-made door kit, which usually includes:

In this case, the entire process of installing the box interior frame comes down to transferring the second parts of the hinges onto the frame parts with your own hands, assembling the holes with self-tapping screws and installing them in the opening.

The entire job will take less than two hours. One of the options for installing interior doors with your own hands in the video

The only drawback of the above scheme is that not all manufacturers modern models interior doors manufacture their products in kits designed for do-it-yourself installation. Most often, the customer buys a door leaf, and the trim and frame parts are purchased with the expectation of installing an interior door with a frame on their own.

How to install an interior door with your own hands

First of all, you need to lay out the door leaf on a level area. Next, the selected pair of beams is laid to the left and right ends of the sash. Using a tape measure, we measure the width and expected height of the future supporting frame. Then, using a building level and a tape measure, check the dimensions of the interior passage.

Important! This is done in order to determine whether the platbands will cover the edges of the hole in the wall, and what thickness of additional elements should be used.

If you “miss” the height or width of the frame, you will have to redo the trim yourself or, even worse, you will need to raise the interior door in height.

Assembling a door frame frame of any size

In order to install the interior door without distortions, it is important to choose the correct distance between the left and right posts so that the door leaf fits into the frame with a small gap, no more than 2 mm on each side. In this case, the door will open freely without jamming in the hatch.

The easiest way to assemble the frame with your own hands is using a clamp, a saw and two blanks. Vertical posts, as in the case of preparation, are placed at the ends, leveled and secured with clamps.

On the side of the upper and lower edges of the canvas, an allowance equal to the thickness of the timber is left on the workpieces. At the same time, on the left allowance, a cut line is applied with your own hands at an angle of 45° for further joining with the horizontal crossbars of the frame. Without disassembling the structure, markings are applied to cut out the grooves for the canopies, lock and handle.

If the interior door is too wide or complex shape, then usually at this stage they check the conformity of the configuration of the frame with the door to the shape of the interior opening. To do this, a pair of nails are driven into a wooden plank at a distance from each other equal to the outer width of the frame. The plank must be secured above the opening, and a couple of plumb lines are hung on the nails. If the gap between the frame and the wall is 10-15 mm, then the calculation is correct.

Installing hinges on an interior door

After all checks have been completed, it is necessary to cut out mounting grooves for the awnings in the canvas using a chisel or carpenter's knife and hammer. The easiest way is to mill a niche using hand router, but, as practice shows, the work can be done with your own hands and without expensive power tools.

If this operation is difficult, then for interior doors you can use overhead hinges or models for drilling. For installation you only need to drill holes for screwing in the fasteners.

We fix the frame in the doorway

• Mark the level of the upper horizontal cross member of the frame with a marker on the steppe, this will help to complete correct installation horizontally and vertically;
• Using wedges and a building level, we level the frame vertically and horizontally with our own hands. We fix the position of the frame in the opening wooden plugs and wedges.

Advice! If the frame and door leaf are light in weight, then the frame can be fixed with mounting perforated petals to the wall of the interior partition.

Next, you need to blow out the space between the frame and the wall with polyurethane foam; while installation is being carried out on the polyurethane foam, you need to check it again and, if necessary, finally level it vertically using a long building level. Apply a small amount to the top mark building level and, if necessary, we adjust the frame to the required height.

Installation of door leaf

After the loot is firmly fixed with hardened foam, it is necessary to install the mating parts of the canopies. To do this, initially the door leaf is raised with wedges so that there is a gap of 1-2 mm between the threshold and the lower edge.

All that remains is to install the sash on the awnings, and you can move on to decorative finishing interior doors.

Installing trim on interior doors

Covering the frame with platbands is not particularly difficult. First of all, install the vertical trim strips. The height of the plank is measured according to the mark made earlier, after which the platband is applied to the frame and the cut line is marked at an angle of 45 degrees.

Advice! It is best to make the cut yourself using a thin hacksaw blade for metal. First stick tape onto the cutting line. The plank is nailed with wallpaper nails or placed on glue.

The second vertical casing is installed in a similar way. After the installation of the vertical parts has been completed, you can mark the cut line on the horizontal strip and install it on the door frame in the same way.

What are the sizes of extensions for interior doors?

Additional strips are used as additional element to increase width or thickness door frame. Most often, installing extensions on interior doors is required in a situation where the wall is much thicker than the canvas, and there is a gap between them that needs to be closed.

The width of additional slats ranges from 10 mm to 200 mm, for interior designs the most popular size is 10-20 mm, and often, due to the non-standard profile of the slot, the extensions have to be ordered or cut out with your own hands from the trim strips.

How to install extensions on an interior door

If, after installing the box, the unpleasant fact is discovered that the vertical plane of the frame is recessed into the space of the interior opening relative to the wall surface, then the only way to correct the situation is to use additional strips.

You must first determine the size of the extension; to do this, place a building level on the wall and use a ruler to measure the distance to the front edge of the box. Thin strips are nailed with wallpaper nails, wide extensions are glued to the frame.

Professional advice on how to install interior doors

Among the features of installing home doors, the following problem areas can be noted.

Before installing the trim, you need to make sure that the frame or additional strip is located in the same plane with the surface interior wall. Otherwise, even if you do it perfectly with your own hands, a gap will definitely appear between the platbands.

The second problem we have to face is sagging doors if installed incorrectly. To correct the position, you need to remove the door leaf, place washers, or trim the edge and install the door in place.

Conclusion

Installing interior doors with your own hands will require a little practice in installing awnings and extensions, but in general the work is not difficult, and with the right skill you can hang the door in a few hours. The craftsmen claim that with each installation, the quality of their DIY work doubles.

Until recently, installing interior doors with your own hands was quite a difficult task and required serious experience and skills from a person. Now everything has become much easier, having a good tool and knowing the procedure for installing interior doors, any House master able to finish work in a day. Next, we will show you step by step how to properly install an interior door in two ways.

Options for interior doors.

Before installing an interior door, you must first select it. When choosing, there are 2 main criteria - the size of the structure and the material from which the doors and the frame to them are actually made.

Material selection

It is not so important to install an interior door in a wooden house or in a room in a city high-rise building; the design must not only be beautiful, but also reliable, and this primarily depends on the material.

Fiberboard is perhaps the most common option. The design is a hollow box closed on both sides thin sheets Fiberboard and based on a frame made of wooden blocks.

There is no need to rush to install such a door; it is, of course, light and cheap, and it may look quite decent, but the reliability is not all right; such a structure can even be broken with your fist, plus there is a high probability that in a couple of years it will begin to delaminate.

MDF is golden mean between cheap fiberboard and good wooden structure. The array is dense, durable, and most importantly completely environmentally friendly. Self-installation of interior laminated MDF panels at home is an excellent solution if there is no money for installers, and beautiful door I want to.

The MDF canvas must be laminated with high quality, then it will not be visually different from wood.

Natural wood - traditionally it is believed that installing wooden doors is the most the best option, but this is wrong, here you need to look at the quality and manufacturer. Believe me, sometimes it is better to install interior doors from good MDF laminate, rather than take a damp pine tree, which will fail in six months.

When purchasing wooden panels, you need to carefully evaluate the quality of the wood.

If you decide to change interior doors and you have a high-quality wooden panel, then you don’t have to touch it, you can only replace the panel. In this case, the technology for installing interior doors will be much simpler.

GOSTs, tolerances and unclear issues

The size of the doorway for installation is perhaps the most important of initial parameters. To this day, all such designs are made according to Soviet GOST standards; by the way, the Chinese also focus on these dimensions, but in Europe, despite the supposedly uniform standard, many countries do it their own way.

So if our minimum blade width starts from 600 mm and then in increments of 100 mm, it reaches 900 mm, then France produces blades starting from 690 mm, but the graduation also occurs in increments of 100 mm.

Germany, Spain and Italy, as well as all countries of the former socialist camp, in this regard are guided by almost the same standards as our manufacturers.

Interior doors have clear standards that need to be checked before installing an interior door yourself.

As for tolerances, a gap of 3 mm is left on the sides and top between the box and the canvas itself. According to the rules, there must be at least 20 mm between the floor and the canvas. This gap is needed for normal ventilation in the apartment.

Along the perimeter of the frame in block buildings, you can leave any gap, up to several millimeters, the main thing is that the frame is level, but if we cut doors in a wooden house with our own hands, then we set the tolerance to at least 15 mm, it is needed in case the house fails shrinkage

When choosing an interior door, installation is already final stage, before this you need to read the description in detail, because the price may be indicated depending on the configuration, there are 3 options:

1. Only the door leaf is sold - this option is good if the door is planned to be installed on an old frame;
2. The canvas is sold together with the box, but the box comes disassembled; here, even before installing the interior door with your own hands, you will have to cut it to size and assemble the box, which in most cases is even good;
3. Fully assembled blocks with a finished box, canvas, locks and hinges are installed only if preparation of the opening is not required. There it is enough to cut the racks to the height and install the interior door yourself.

Do not forget that it is not enough just to install interior doors in the opening, complete installation The design of an interior door involves the arrangement of platbands, extensions (if necessary) and fittings, so it is also advisable to take them right away, otherwise the shade may not be suitable later.

Installation of interior doors will not be complete without platbands and fittings.

There is one more important question– when to install interior doors during renovation? So, the instructions for installing interior doors say that such structures are installed at the very end of the renovation, after finishing the walls, floor and ceiling, but before installing the floor skirting boards.

Two mounting options

We’ve sorted out the dimensional tolerances and other pressing issues, now it’s time to find out how to install an interior door yourself. But to assemble and install the structure, we need a tool.

A few words about the instrument and accompanying material

To install interior doors we need:

• A hacksaw for wood, but ideally it is better to have a miter saw, it does not leave chips, plus you can put it there exact angle cutting;
• To create openings between the frame and the wall, wedges are required;
• Hammer;
• Chisel;
• Screwdriver;
• Electric drill;
• Plumb;
• Level;
• Pencil;
• Roulette.

Install an interior door yourself without good tool unreal.

Important! Safety regulations strictly prohibit cutting wood with a grinder. If you value your health, don't even think about it.

From auxiliary materials To install the doors you will need:

• Polyurethane foam;
• Masking tape;
• Self-tapping screws different sizes and sections;
• Anchor bolts with dowels.

Preparing the opening

Ideally, before installing an interior door, the edges of the walls should be, if not plastered, then at least leveled with cement-sand mortar.

But in real conditions, preparing a doorway for installing an interior door ends with adjusting the dimensions to fit the frame, because then the unflattering cracks will foam and be covered with platbands, so there is no point in creating special beauty.

It is advisable to level the doorway before installing the frame.

There's one here important point: often installing a double interior door requires widening the opening, so when we're talking about about the walls, then they can be “redrawn” as you see fit. But if the wall is load-bearing, then a slight expansion of no more than 5–7 cm is allowed, otherwise there may be problems both with the wall and with the law.

Box assembly

You can assemble a door frame with your own hands in two ways - by cutting the corners of the top strip at 45º and joining the strips at right angles. Both methods are good, but it is believed that an angular connection at 45º will look more elegant.

Really high-quality corner trimming can only be done with the help of a trimmer; if they assure you that an ordinary plastic miter box and a hacksaw for wood will do for this, don’t believe it, it can ruin the boxes that were made.

The vertical posts are cut first at 45º, after which you can proceed to trimming the upper horizontal strip. In order to set aside 3 mm, it is convenient to use a piece of fiberboard as a template.

We measure the gap relative to the top bar with a template.

• You place the top strip cut on one side and move it along the cut of the template;
• Then go to the opposite side of the door and, using the same template, mark the cutting line.

Trimming the top strip at an angle using a trim saw.

Now we lay out the finished, trimmed frame strips on the floor and once again control the dimensions.

This is what a door frame looks like cut at an angle.

• The box is fastened in stages. First you need to tightly connect the planks together the way they should be;
• When screwing in the screws, the frame slats may crack; to prevent this from happening, before assembling, we need to drill channels for the screws. This is done with a 2.5 mm drill (our self-tapping screw is 3.5 mm);

Preparing to fasten the box.

• Now you can screw the screws into the ends of the box on both sides, and there should be 2 screws on each side of the corner.

There is a small nuance here; the vertical strip of the box to which the hinges will be attached does not need to be fully tightened on both sides; we will still have to remove it.

Fixation of the box with cutting at an angle.

If you don’t have a miter saw in your arsenal, then it is better to attach the frame slats at a right angle. It may not be as aesthetically pleasing, but the step-by-step instructions will be somewhat simpler.

We start by trying on the top cross member; we will embed it between the two side posts. Some craftsmen mount the crossbar above the side posts, there is not much difference, here it’s more convenient for everyone.

Along the perimeter of the frame we have a side, into which the door leaf rests when closing. To embed the top cross member on the side posts we need to remove this side. To do this, we attach the upper cross member to the rack, mark it, cut the side with a hacksaw, and clean the place for installation.

Now all we have to do is insert the top bar between the two side posts, drill holes for a pair of screws and secure the inserted bar with self-tapping screws.

If you decide to put the bar on top of the racks, then you will need to trim the inner edge on the top bar, then drill and drive the screws from above, as shown in the diagram below.

Do-it-yourself installation of a plank placed on top.

Installing hinges and handles

For a door, installing hinges is one of the most important stages. In principle, you can embed a lock and attach hinges after installing the frame in the opening, but if you are installing the doors yourself (without help), then it is better to do this right away.

Loops can be overhead or hidden. It’s easier to work with overhead butterfly hinges, since you don’t need to cut anything in the door leaf and frame, so we’ll start with them.

A little advice: if the door should open on right side, then you insert the hinges on the right, respectively, for left-sided opening, the hinges need to be attached to the left post.

Installation of hinges begins with markings on the canvas itself. According to the rules, the distance from the top or bottom point of the canvas to the loop should be 200 - 250 mm. You can measure with a tape measure, as in the photo below, but if you don’t have a tape measure at hand, then use the loops themselves, there standard size equal to 100 mm.

We make markings for installing hinges.

Don’t get confused: the small (inner) part of the butterfly hinge is attached to the door leaf, and the large part is attached to the frame post. Before screwing in the screws, you need to drill holes under them, only after that the screws are driven in.

All hinges have recesses for the screw heads, so make sure that these recesses “look” up. If the hinges are installed the other way around, the heads of the screws will remain above the hinges, and therefore the doors will not close completely.

Drill holes for butterfly hinges.

We have the box almost assembled, now we put it on the floor and put the door leaf inside. As you remember, we should have 3 mm around the perimeter of the canvas, so we immediately insert as many homemade fiberboard templates (3 mm thick) between the box and the canvas as possible.

One part of the loop is screwed to the canvas; to screw the second part of the loop to the box, we make a mark on the box. Next, unscrew the self-tapping screws securing the supporting vertical bar and screw the mating part of the hinges to it. Then we return the box strip to its place and fix it completely.

We screw the hinges to the vertical post of the box.

Installing hidden hinges yourself is not much more complicated than the method described above. The difference is that you need to cut grooves for the hinges in the door leaf and frame. This is done using a mallet, chisel and knife.

Cutting grooves for mounting hidden hinges

As for the installation door handle, then you can read about this in detail and also watch the video in this article. And don’t forget that the hinges must be lubricated; you can learn about lubrication rules.

There are different methods for installing interior doors in a wall opening, it all depends on the specific conditions. Next we will look at the simplest and most popular options.

Method number 1. Classic

On this moment In our case, the frame posts must be cut to the height of the opening, the hinges and lock are cut in, the door is closed, and 3 mm thick templates are inserted between the door leaf and the frame.

When the door block is inserted into the opening, first of all, wooden or plastic wedges are driven around the perimeter; they will hold the block until it is finally secured.

Classic scheme for installing interior doors using wedges.

Fixing is a rather important moment; here we position the block vertically and horizontally. Keep in mind: the wall is not always strictly vertical, so check the box with a plumb line.

It is better to check the vertical by plumb.

To prevent the door block from falling out from a strong push, it must be firmly secured with anchor bolts or at least long self-tapping screws. We recommend using anchor bolts with a thickness of 6 - 8 mm.

The principle is simple:

• Drill a through hole in the box and lightly drill into the wall;
• Remove the door block and drill holes for dowels at the drilling points;
• Place the box in place and secure it with anchors. The box should be clearly level, since we have already verified everything before.

If you fix the box with long self-tapping screws, then they are installed around the entire perimeter at intervals of half a meter, but the heads of the screws need to be hidden somehow. They can be covered with a decorative strip or plastic covers.

Anchor bolts are powerful things and 3 points are enough to fix the box - two points under the hinges and one under the lock plate. In combination with polyurethane foam, this is enough.

Now we fill the perimeter of the box with polyurethane foam. We move from the bottom up, the foam needs to be blown out without fanaticism, because when it expands it can squeeze out the door frame.

Plus, at the time of blowing in the foam, the door block must be assembled and three-millimeter templates must be inserted around the perimeter, this will protect the frame from deformation.

Remember: the door block cannot be mounted only on “bare” foam (without screws or anchors).

Method number 2. Metal hangers

If fastening the box with self-tapping screws or anchors is not suitable for you, the same can be done using metal hangers. These hangers are used for mounting frames under drywall.

Using hangers to fix the door frame.

The technology is similar:

1. Assemble the box;
2. Insert the box into the opening and level it;
3. Fix the box with wedges in the opening;

1. Bend the wings of the hangers along the wall;
2. Mark the entry points of the dowel-nails and drill holes for them;
3. Attach the wings of the hangers to the walls with dowel nails;
4. Fill it with foam and wait for it to harden.

The size of the frame for double-leaf interior doors is twice as large, which means there is a higher probability of the posts and crossbars being squeezed out by foam, so installation on hangers is optimal here.

Conclusion

Both of the above methods have been tested in practice and work perfectly. For the same craftsmen who want to install interior sliding doors We have prepared step-by-step instructions.

Installing interior doors with your own hands is not as difficult as it seems.

Installing an interior door on your own is not a difficult job. A simple step by step diagram, starting from choosing your favorite interior door in the store and ending with self-installation interior doors with step-by-step photos.

Interior doors can be divided into several types

Manufacturers on the market door designs offer quite a wide the lineup. Ready-made interior doors can be made of different materials. The most common types of materials are: , , .

Helpful information:

1. Fiberboard – door: the frame is made of wood and covered with fiberboard sheets with lamination. The advantages of such doors include: low cost compared to other types, light weight, which makes it possible to deliver them from the point of sale to the house on your own, and ease of installation. Considering these points, they are popular among customers, thanks to which their wide range is most often presented in stores.

Among the disadvantages, we can note the low strength of the fiberboard itself, which is why the door breaks and becomes unusable quite easily, poor resistance to humidity, the door can twist. Therefore, we do not recommend installing it in bathrooms with weak exhaust; this material loves dry rooms.

3. Natural wood– interior doors made from this material are the most durable. Their price directly depends on what type of wood was used for their production. Doors from valuable species wood are used for installation in rooms with an original design; they will fit perfectly into classic interior. The width of interior doors is adjusted to the size of your opening.

The list of interior doors by type can be supplemented with steel ones, but these types are not very popular among the general public, so they are not included in the article for a detailed description.

Come here if you are interested in and.

Types of door frames for interior doors

The correct interior door should be in reliable box for a door, because its quality will determine how long the door will last, as well as the design of the doorway of your room. Door frames can be divided into three main types.

1. Fiberboard box. It looks pretty decent, but when choosing a box made of this material, the strength of the entire structure will be in question. The middle of the frame bar sag from its own weight, not to mention possible deflections from the weight of the door leaf itself. Since the main components of fiberboard, to put it simply, are glue and paper, it must be taken into account that they are very fragile and not durable. It is not recommended to hang doors made of wood and MDF on them due to their heavy weight.

2. Raw wood box. The cost is at the same level as boxes made of fiberboard, but unlike the latter, boxes made from dry profiled timber have higher strength. Therefore, when choosing between boxes made of fiberboard and boxes made of untreated wood, we recommend choosing the latter. It is also necessary to take into account that you will need additional materials to finalize the box.

Photo - Untreated wooden box

3. Laminated wood box. Does not require final finishing, as it is already laminated with paper. And here there is one important point: when choosing such a box, the quality of lamination is very important. If thin paper was used for this, there is a high probability of abrasions, scratches, cracks, and the coating loses its appearance. Possibly more quality option there will be a box made of untreated wood with independent finishing and painting.

Also the entire doorway of the interior door may require additional processing after installing the doors. Everything depends on your opening, its size, the location of the door in it, and the interior of the room.

For such processing, you can use additional strips and platbands. The necessary kits can be purchased at the store. We recommend that you determine whether they are necessary after the final installation of the door in order to understand which one. final finishing you need. After all, the purchase additional materials- This additional expenses, which in the end may not be necessary.

An example door with a frame made of fiberboard is considered. If you need to install wooden boxes, you need to follow the same steps. Installation will be simpler, since wood is stronger than fiberboard.

Step 1. Selection tools and necessary additional consumables. For installation you will need:

• saw;
• electric drill ();
• drills 3 mm and 4 mm for wood;
• drills 4 mm and 6 mm for concrete;
• screwdriver;
• roulette;
• pen;
• wood screws;
• quick installation dowels;
• polyurethane foam.

Step 2. Determine the scheme for attaching the frame to the doorway of the interior door.

Photo - Diagram of fastening the door frame in the opening

The figure shows a diagram of fastening the door frame in the opening. As you can see, the interior door (2) is installed in a frame (1), which is secured in the opening with screws (3). We blow foam between the wall and the box (4). The process is as follows: we install the box in the opening, fasten it to the wall, and foam it.

Photo - Disassembled door frame and door before installation

If, after installing the door, its threshold cannot be hidden in the floor, for convenience, choose a U-shaped frame without a threshold. It does not have a bottom crossbar, so there will simply be nothing to interfere with your walking.

Step 3. Assembling the door frame.

Photo - The door frame must be assembled for ease of installation

The purchased box must have hinges attached. The door should have a cutout for the handle, as well as for door lock interior door. We begin assembling the door frame. It is necessary to connect all parts of the box together and adjust it to the dimensions of the opening. The factory length usually comes with a margin of 5 cm.

The surest option not to make a mistake is to assemble the parts on the floor the way they should stand in doorway. Special attention needs to be addressed metal bases hinges, they should stick up so that the door can be hung on them from above.

Choose the opening side depending on the rooms between which the doors are installed. From small rooms, such as a bathroom, pantry, it is better to open doors outward, from large rooms in the corridor - inward.

Photo - Correct position of the end strips

We attach the top bar with self-tapping screws. The end strips (1) should lie along the line. If there is no line, then the bar is lying incorrectly and needs to be turned around.

Photo - Screws should be tightened after pre-drilling

Taking into account the structure of the fiberboard and its strength characteristics, in the box, before screwing it in, it is necessary to drill holes with a wood drill with a diameter of 3 mm. We carry out this action so that our box does not crack during the assembly process. For the same reason, the screw attachment points should be located closer to the center, away from the edges and corners.

Photo - Assembled box

To fasten the strip, four self-tapping screws will be enough, two on each side.
If the door lies horizontally on the floor, place it underneath soft cloth, this way you will reduce the likelihood of damage to the laminated layer.

Photo - Factory stock box

We will cut off the factory stock of the box (the protruding edge). To fit the box, we accurately measure the dimensions of the doorway of the interior door. And we transfer it to the door frame, taking into account a gap of minus 1-2 cm on all sides to allow foaming. We recommend double-checking the dimensions of the structure several times.

Photo - Cutting line for the excess part of the box

It is better to cut off the protruding excess hand saw. It is advisable not to use an automatic saw to avoid damaging the coating.

Photo - Trimming excess with a handsaw

As a result of all the manipulations, we get a U-shaped door frame, ready for installation in the doorway of the interior door.

Step 4. Installing the box in the opening.

We place the box in the doorway. Level it up. We check the correctness and evenness of the assembly of the box by hanging the door on its hinges and closing it.

Photo - Checking the position of the box with a level

Photo - Drill diameter 4 mm for wood

The box installed in the opening must be secured with self-tapping screws. Remove the end decorative strip and drill 7-8 through holes on each side. The distance between the holes is 25-30 cm.

Photo - Drilled box

The wood drill is not designed for drilling walls; we only use it to drill fiberboard boxes. Then we again check the position of the box using a level, since it could have shifted during the drilling process. If there are no changes, we begin to drill the wall. Using a thin concrete drill with a diameter of 4 mm, through the holes in the box, we apply markings to the wall. You cannot completely drill through the wall through the frame, as this can damage it. The hole diameter is 4 mm; if you make it larger, the screw heads will fall out. Next, remove the box from the opening and begin making holes using a 6 mm diameter drill. If the wall is made of brick, the holes for installation should be in solid brick, not in masonry seam, in which the dowels hold very poorly.

Dowels are installed in the finished holes. We fix the box in the wall using self-tapping screws. For convenience, you can use a screwdriver or drill with an attachment for the screw head. Do not screw in the screws completely; the box may bend. To avoid deflection, wedges can be lined. To check the evenness and absence of distortions, during the process of screwing in the screws, additionally check the box for level.

Upon completion of installation, the box is checked from the side of the room using a level.

Step 5. Installing the door on the hinges.

How to install an interior door? It is enough to put the door on the hinges

If it is a door made of fiberboard, given its weight, this can be done alone. After installing it, we will try to open and close it. In the closed position, the gaps between the frame and the door should be about 3 mm.
