It is a frame structure that is attached to the wall, and inside which the door leaf is hung. More recently, 20-25 years ago, even entrance doors were exclusively made of wood or plywood. In the 90s, metal entrance doors, and accordingly, their door frame is made of steel. About 10 years ago, aluminum and plastic interior doors came into use, which are made with a ready-made frame from the same material.

Made from chipboard, MDF, plywood and even fiberboard, then the box, trim and are made of solid wood, more often coniferous species, or from MDF. Woodworking enterprises have launched the production of beams and panels made of laminated MDF.

Can be made from MDF - fibreboard medium density, made by hot pressing. Everything is made from this material necessary elements. All you have to do is adjust them to size. Particularly relevant for arched openings. Assembly from MDF is carried out in the same way as from ordinary wood, but working with this material is much easier. All parts are fastened together using glue or self-tapping screws.

Tools

To install interior doors, you will need the following tools:

  • tape measure to take measurements of the opening and parts,
  • an ax or a large hammer,
  • screwdriver or screwdriver,
  • nail puller
  • chisel,
  • Bulgarian,
  • level,
  • Master OK,
  • spatulas
  • Bulgarian,
  • jigsaw,
  • chisel,
  • miter box.

How to dismantle an old door?

Dismantling the old interior door is done in the following order:

  • First, remove the fittings: handles, locks, latches.
  • Inspect the hinges. Sometimes they are separate. If you can remove the canvas, remove it.
  • For solid hinges, remove the screws. Unscrewing is done from bottom to top. Inexperienced craftsmen often make this mistake - first they unscrew the screws from above, and then they have to ask someone to hold the canvas. If you start from the bottom, then the door hangs until the very end on the top hinge, on the top screw.
  • Place the door leaf to the side. Disconnect the hinges completely. Inspect the platbands, where they are fixed and in what way. Disconnect them. There will probably be fasteners for the accessories under the cash. These can be either nails or screws. Unscrew the self-tapping screws, and if there are nails, pry up the extensions with an axe. Unplug them from the box
  • Find the places where the beams are attached to the wall and free the box from the fasteners. In old Soviet-type houses, it may not be secured with screws to the wall. Inspect it, if there are no nails or screws, try to knock it out of the opening.
  • extra pieces of plaster, boards, putty. It's ready for you to work with.

How to install a new door in an old frame

During the renovation process, this option is also possible: a new door in an old frame. If you intend to replace a damaged old door, then you do not need to dismantle the strong frame. You only need to remove the door by unscrewing the hinges. You can take measurements for a new door using the old door leaf. To prepare the doorway for installing a new leaf, inspect the frame and hinges. Pay attention to whether gaps have appeared between the boards and the beams of the main structure. You may have to remove the platbands. At the same time, check the fastening of the accessories. If the planks are nailed, knock them down and tighten an additional couple of screws. Put the trims back in place.

You can screw the door with old hinges, or you can install new ones. Then hammer wooden chips coated with glue into the old holes for the screws. Because the new hinges may partially coincide with the old holes, or the screws for them will be thinner. In any case, the choppers will seal the holes, and the hinge will not become loose under the weight of the door leaf.

You can hang the door. Inspect the lock (if there was one on the door). If you keep the old one, then when installing the lock, adjust the lock latch to the strike plate.

How to prepare a doorway for installing a frame?

Sometimes apartment owners, wanting to change the interior of the room, change the design of the interior doors. The expansion of the doorway is justified by the desire to install double-leaf swing or folding doors (book, accordion).

In houses with high ceilings, sometimes they increase the height of the doorway, change the shape of the opening, making the top semicircular or arched.

The methods of this work depend on the material from which it is made. interior wall. The easiest way to work is with brick or wooden walls.

But the doorway in brick wall it is structurally complex because it has more irregularities than other walls. This gives errors in measurements. And this must be taken into account when changing the size of the opening. The edges of the wall must be leveled by plastering, then installing the door big problems will not amount to.

To expand a doorway in a brick wall, it is enough to brickwork remove a row of whole bricks from the edge of the opening, level its line with half bricks and a cement-sand mixture. To do this, you will first need a chisel and a hammer, and then a level, trowel and spatulas.

IN wooden wall You can widen the opening using a circular saw or grinder.

It is much more difficult to widen the opening in reinforced concrete panel. In this case, you will have to arm yourself with a hammer drill and a grinder. The hammer drill will drill and beat out the 6-stone, and you will use a grinder to cut the metal rods of the frame. The edge of the opening at the expansion site must be leveled and plastered as much as possible.

Sometimes, doorways are unreasonably wide, which complicates the arrangement of furniture, and there is a desire to make it smaller. To reduce the opening by 8-12 cm, you can insert a thick beam between the wall and the frame, secure it with long self-tapping screws (by the way, the screws can be deepened into the timber up to 4 cm by drilling a hole for the head with a No. 8 drill), foam it and seal it with plaster . You will attach the box to the beam. Installing thick beams will allow you to reduce the opening to 24 cm. To reduce a brick doorway by 25 cm or more, you will need plasterboard, or bricks, cement and sand. Drywall can be used to reduce thin walls covered with a thick layer of plaster. In this case, the plaster must be knocked off the wall and the drywall must be overlapped. The added part of the wall also needs to be plastered and finished so that it merges with the main one.

How to install a frame in a doorway?

Preparing a doorway for installing an interior door begins with the frame. It is recommended to install it before the floor is laid (filled). The box consists of beams 7x4 cm in size connected by the letter P. This is if you do not intend to install a threshold. Assembly door frame with a threshold has a closed shape. It is necessary to correctly calculate the height of the threshold so that it is not below the floor level and is not too high. 3-4 cm is enough for him.

The frame and threshold parts must be made in such a way that a protrusion is embedded in the beams, preventing the door from overlapping and closing on the other side. Stops help increase the noise and heat insulation of doors.

The corners of the box and extensions should be sawed off on a miter box at an angle of 45° and fastened together with self-tapping screws, lubricating the cut with glue. The door frame can also be assembled using the tenoning method, since the frame is still a solid structure. The door is assembled on a flat surface to avoid distortions.

You need to install the box like this:

  • so that it rests against the top edge of the opening. You may need to hammer in wedges to seal. Either at the top or at the bottom (if the bottom edge of the box is hidden under the floor). Cut off the excess wedges hammered on top so that they do not peek out and interfere with the installation of the extensions.
  • WITH outside the box should be mounted in line with the wall.
  • And at the same time, use a level to check the evenness of the box, and use a square to check that the corners are correct.

The door frame is fastened to the opening using self-tapping screws.

  • Mark the points where the screws will be tightened;
  • drill holes in the box with a No. 4 drill;
  • Mark the location of each hole with a pencil on the wall;
  • remove the box from the opening;
  • drill Pobedit drill#6 holes in the wall and hammer in the nylon dowels.
  • Reinstall and level the box so that drilled holes agreed. Drive the mounting wedges into place. Screw the box with self-tapping screws.

A stable box will not create a large load on the fasteners you use to secure it to the wall.

If the wall thickness is more than 7 cm, then additional boards will be required - boards that will disguise the wall of the opening. They are attached later, when the box is installed; there is no need to connect them together in advance. But the upper edges of the racks and the top bar should also be sawed off at an angle of 45°

How to install and secure a door in a frame?

The box is exposed and secured. Now you need to hang the door. For this

  • Insert the canvas into the box.
  1. If you have a threshold, place three or four matches or dental sticks under it. This is necessary so that the door does not rest heavily on the threshold, and then you do not have to touch it.
  2. If a threshold is not provided, then place planks or plywood 5-6 mm thick.
  3. If you plan to lay carpet or linoleum within the door, then the door should be raised a centimeter.

The installation of interior doors must be carried out taking into account all the “ifs”, then it will close freely, without resting against the bars either on top or on the sides. The door should fit freely in the frame. On the sides and top the gap should be 2 mm, on the bottom - taking into account the “ifs” described above. Make sure all conditions are met. You can also insert matches between the frame and the doors. Everything is fine? If the door rests somewhere, mark it with a pencil - in this place you will have to work with a plane to remove the excess.

  • Mark the loops. Attach the hinge and mark the height of the hinge on the frame and on the door at the same time with a pencil. Mark the thickness of the hinge on the door. Do the same with the bottom loop.
  • Also mark with a pencil the location of locks, handles or latches. Now you can. The assembly of interior doors, fitting and fastening of fittings are carried out until the door leaf is secured in the frame. It is also better to paint and varnish it while it is not installed in the box and while there are no fittings on it. But let’s assume that you purchased a door that has already been finished.
  • You can make a recess for recessing the fittings using a jigsaw, or manually using a hacksaw and chisel.
  • Screw the hinges and other hardware to the door. Place the canvas against the box and start screwing the hinges.
  • Check how your door opens and closes.

How to secure extensions and platbands

Extensions are installed if the opening is thicker than the frame. Their width should correspond to the distance from the box to the edge of the wall. Attaching the extensions to the main beams is done with self-tapping screws. For greater strength, the end of the extension can be lubricated with glue before tightening. The void between the opening wall and the extension must be foamed with polyurethane foam.

The width of the platbands should be such that on one side it is flush with the frame, and its other edge extends 1-1.5 cm onto the edge of the wall. This is the final stage of installing the box. They form a design element and therefore should look attractive. The trim should be installed before the baseboards are nailed down. Sawing should be done at an angle of 45 degrees. The fastening of cash should be done so that the fastening elements are not visible. These could be liquid nails.

Platbands can be

  • Wooden,
  • Plastic,
  • From MDF.

The main condition when choosing cash is the appearance and compliance with the design of the door or interior of the room.

Hello. I have one question. Is it possible to leave the old frames when installing new doors?

Expert answer

Hello. Install new door It's certainly possible in an old box. However, this is very difficult and requires compliance with special rules and recommendations:

  1. The door must have perfect exact dimensions, fully consistent with the size of the box and the previous design;
  2. Before purchasing a new door, take accurate measurements of the old one;
  3. New door structure in the presence of non-standard sizes, you will have to make it to order, which will cost more;
  4. An old box may have various deformations and damage over time that need to be repaired;
  5. New door if it has more weight than the previous one, will place a significant load on the old box, which will deform over time.
  6. If the new door is even slightly different in size, it is necessary to install wooden blocks in the places where the gaps form.

When renovating a room, it is not always possible or willing to install new door blocks with complete removal old - this may entail repairing walls and floors for various reasons:

  • new door frames do not cover old holes in the floor
  • there will be damage to tiles or wallpaper along the perimeter of the casing
  • unreliable walls and partitions (during dismantling and installation, the geometry of the doorway may be destroyed).

Therefore, we suggest installing new elements door block without dismantling old box, in other words, put new doors in old frames.

From many years of experience in updating and restoring doors, we can highlight doors made from laminated pine. They extremely rarely deform and change the geometric parameters of the canvas.

;

Conclusion: it is possible to install a new door in an old frame. But as a rule, such a process is more complex and lengthy. If you decide to go with this option, try to replace the old door with a similar one or the same size.

Have you decided to change your interior door? You don’t have enough money for a set with a box or you think that the old box is still in good condition? Under no circumstances should you install a new door into an old frame. Why? We will cover cases of installing new doors in an old frame in this article.

In progress cosmetic repairs You can also find situations where owners try to install a new door leaf in a frame from under old door. In what cases is this option allowed:

  • If the wall may be damaged when dismantling the old box.
  • Replacing one canvas with another for various reasons, but of the same batch.

And in these cases there may be problems, since in production identical doors may differ in size by 1-2 mm, and this is detrimental to the gap between the box and the canvas.

The new door may have smaller size than the old one and it will form a gap. The appearance of such a door is not very aesthetic.

With gaps in the box, thermal insulation and sound insulation may be compromised. It is also possible for the door to open spontaneously; in this case, the lock in the door does not fit tightly into the frame due to a gap.

The new door is larger than the old door frame, then such a door cannot be installed at all. Many people try to adjust the door to the size of the frame by cutting along the inner edge. Don't you dare do that! In this way, the door coating can be damaged and it can be thrown away.

All interior doors from the same company and from the same batch look aesthetically pleasing. Photo: tgorlovka.com

Not the most important, but the argument why you shouldn’t install a new door in an old opening is the discrepancy between the color of the door and the frame. The ridiculous appearance will scare you and sooner or later you will still decide to install full set. Do not forget that you may encounter size discrepancies if you buy one box separately. Don't waste your money, buy and install the kit right away.

The fittings on all doors are located differently. Photo: tgorlovka.com

The location of the hinges depends on which direction the door will open; in a new door, the fittings may simply not match. The hinges and locks in old doors are significantly different from new models, so a 100% new door will not fit a frame installed in the 90s.

Summarize

All professionals will agree that replacing the door leaf without replacing the frame would be an unjustified step. Instead of quality door in terms of function and appearance, you will get an absurdly designed doorway that will not fit into any interior at all.

During renovation, sometimes it becomes necessary to update interior opening, keeping the established box. It is connected with the fact that removing the frame from the wall risks causing damage to the wallpaper, destruction of the tiles, and the formation of cracks in the floor when the threshold is removed. Therefore, the owners change all other components of the structure, and the frame is cleaned, treated with putty and painted to match the color of the sash. Replacing door panels does not require such labor-intensive work as dismantling and installing an entire unit, and it is cheaper.

Features of the procedure

In addition, it is worth making sure that:

the opening has an ideal geometry, old frame not skewed, not deformed and ready for further service;

the new product will not overload load-bearing element- it is better to purchase a product from the same materials and the same mass as the previous option.

To ensure that replacing the door leaf of an interior door is successful and does not cause additional hassle, you should:

select loops that will fit into ready-made grooves without requiring cutting new ones;

adjust the sash correctly.

A simpler, although quite labor-intensive, method of installing fittings involves sealing old grooves with putty and subsequent painting. The result of such work depends on the skill of the installers.

Where can I order professional service?

Masters who have at their disposal necessary knowledge, experience and tools, solve the following problems:

maintaining good insulating abilities of the block;

presentable appearance opening;

service life of the structure.

What is important is that the customer gets rid of a lot of hassle and receives a guaranteed high-quality result.

Clarifications, comments and additional conditions to work on installing elements of new door blocks on old frames

When renovating a room, it is not always possible and willing to install new door blocks with the complete removal of old ones - this may entail repairing walls and floors for various reasons:

New door frames do not cover old holes in the floor,

There will be damage to tiles or wallpaper along the perimeter of the casing,

Unreliable walls and partitions (during dismantling and installation, the geometry of the doorway may be destroyed).

Therefore, we propose installing new elements of the door block without dismantling the old frame; in other words, installing new doors in old frames.

From many years of experience in updating and restoring doors, we can highlight doors made from laminated pine. They extremely rarely deform and change the geometric parameters of the canvas. We offer doors manufactured by Postavsky Furniture Center (PMC), Vitebsk region, Republic of Belarus, models No. 7 and 16

More details about the work being carried out:

Preparation of the door block, dismantling of elements. We dismantle the door panels and hinges. We fill the marks from the hinges with automotive putty (hard and durable, it will not fall off on its own). Where possible, we remove the platband. If necessary, apply masking tape to the interface between the door block and the floor, tiles, wallpaper and other surfaces that need to be protected from damage. Two or three days after completion of work, the Customer himself removes masking tape, blotting it with a damp (not wet) rag or brush.

Removing paint from wooden surfaces door frame and trim We produce using thermomechanical method. For work we use professional hair dryers with a power of 1800 to 2300 W. Air temperature in work area from 500 to 700 degrees Celsius. When heated for a short time, the paint begins to bubble, peeling off the wood. In this state, it can be easily removed from the surface of the door with a metal spatula. The speed of the process depends on the number of layers of paint; more layers mean more thermal energy and processing time are needed. If the Customer refuses to remove the paint, the reason for the refusal shall be indicated.

Surface preparation after paint removal. After removing the paint, the surface is cleaned and primed. After priming, putty in places, fill the cracks with acrylic sealant.

Installation of new elements of the door block. We attach the new door leaf to the doorway and determine which sides need adjustment. This action is necessary because each opening in our apartments has its own geometry. There is rarely a perfect rectangle. For this reason, we warn the Customer: we allow gaps between the frame and the door leaf from 1mm to 5mm. Door blocks can be designed for door leaves with a thickness of 30mm. The new canvas has a thickness of 35mm. If necessary, you can increase the box up to 40mm. If the box is tilted, then we will not be able to level it. We will fasten the doors, adapting to this circumstance - it is possible that the gaps between the leaf and the frame may increase or the door leaf will spontaneously open and close. After adjustment, we cut in the hinges. The hinges may be in a new location. We usually mount the handles opposite the old strike plate on the box. We adjust and install the frame painted in two layers.

Painting the door block with colored enamel VD-AK 1035U. We support the National manufacturer and use the products of the private unitary enterprise "MAV" Dzerzhinsk RB. The paint is acrylic, environmentally friendly - without allergenic odors (i.e. it does not stink). For a long time retains elasticity, unlike alkyd paints, which quickly harden and easily chip when hit or scratched. Paint, like PVA glue, is diluted with water, but once it dries, you can’t wash it off with water. You can remove dried paint with 646 solvent or nail polish remover. It can be stored for a long time, does not peel off or dry out over time, do not put it in the cold and keep it in a tightly closed container. I offer a palette of 70 popular colors and shades. Apply with roller and brush. The number of layers is from 3 to 8, so the price can vary up to two and a half times. Drying time for each layer is 30-40 minutes at room temperature(about 20 degrees). The paint is enamel and is completely ready for use. Those. It can be wiped with a damp cloth - it does not absorb water. To increase the service life or change the gloss of the surface, you can apply varnish (during varnishing, a slight change in color is possible, therefore, with subsequent tinting with paint, color discrepancies are possible).

Decorative finishing. It is possible to paint the frame, trim and frame on the glass in one color, and the door panels in another. We suggest making PATINA on the doors with MDF coating- texture highlighting door leaves in a different color.

Care instructions: The paint is enamel, i.e. the surface can be wiped with a damp not hard) fabric with non-aggressive detergents. Rubbing with scrapers and other hard objects is not recommended. If stains that are difficult to remove occur, we recommend touching up with a sponge (you can use a dishwashing sponge). After painting we leave it to the Customer sufficient quantity care paints (from 100 to 200 grams per door). Drying time for the 1st layer at room temperature is 30-50 minutes. Ready to use, i.e. acquisition operational properties- 3 days. Store the paint at a temperature not lower than 0 degrees Celsius in a tightly closed container (it is better glass jar with double polyethylene. lid).

NOTE: The work is performed at the customer’s home or in premises provided by the customer. Work is associated with increased levels of noise and dust. The customer himself takes care of protecting the property from dust contamination. It is better to work on doors before wallpapering.
