Do-it-yourself installation of interior doors without any
Installing interior doors do-it-yourself only theoretically is a simple process and looks like a consistent execution of work on the instructions.
In fact, before starting work, it is necessary to properly assemble the interior doors with your own hands and take into account all the nuances of installation technology, otherwise a new door will “glow” with gaps or not open at all.
The secret to the correct installation of door products is the exact observance of all stages of work, starting with the preparation of the premises, materials and tools, to studying the successful experience of predecessors and recommendations of specialists.A visual aid for a beginner is a professional do-it-yourself installation of interior doors - a video with a detailed description of all the installation nuances. Those who are not inclined to duplicate the plots can get acquainted with the detailed description of all stages of work proposed in this article.
Room preparation
First, it is necessary to prepare the room and complete the installation of the engineering systems in the bathroom, bathroom and kitchen. All pipes for water supply and heating must be installed, observing the slope or entrust the connection of the elements of the water supply system to specialists.
As a rule, crimping and fixing parts of engineering systems are described in detail by manufacturers of products. Therefore, the correct installation of pipes for the heating system can be performed even for a beginner, following the recommendations of experts.
Preparation of the opening

An important stage of preparation after installing screens and stainless pipes for heating with their own hands, is the dismantling of the old box.
Remove the old box must be carefully, trying not to damage the opening. When replacing the door is to listen to the advice of experts and do not try to install the interior door with their own hands in the old box in order to save.
An important stage in the preparation of the opening is the marking, for which it is necessary to determine the location of the handle and the side of opening the door: on / off. In addition, an obligatory preparation step is to clean the opening from loose cement fragments.
The main stages of installation
The classical technology of mounting door products includes several basic steps, regardless of the type of interior door chosen:
- Box assembly.
- Installation of the box (installation in the opening).
- Installing door leaf.
- Installation of additional elements.
- Installation of platbands.
Proper installation of interior doors with their own hands is performed using power tools - drills, screwdrivers, perforators.
If you need to cut the trim along, then it is recommended to prepare a circular saw type "parquet". In addition, a saw or a hacksaw, a building level, a hammer, a pencil, a tape measure, a nail puller, a water spray gun, a hammer, a chuslo, chisels and consumables are useful for installation:
- self-tapping screws, dowels;
- masking tape;
- polyurethane foam;
- wooden struts and wedges.
Tip! Experienced craftsmen when installing the door use a plumb and prefer a wooden mallet, as the rubber leaves traces. It is better to use dowels for fastening the box in the doorway, and yellow-passive or galvanized self-tapping screws for the hinges. Standard "standard" self-tapping screws, which are supplied with the product, are not recommended for installation.
Wedges for fixing the product is better to make in the process of installation of the bars and boards. Preliminary preparation of wedges of several sizes can be time wasted, as the exact parameters of the products are determined “according to the situation” - during the installation.
Step 1. Build the box
First you have to assemble interior doors with your own hands - to connect the parts with screws. Before starting the assembly, it is recommended to retract the gaps according to the floor covering. For residential premises it is recommended to observe 10 mm clearances.

Assembly procedure:
- To cut down the stitching beam under the loop: attach two beams, mark the line, cut and carefully cut from the end of the chisel.
- Connect logs (loop, stitched) in a right angle with the help of screws.
- Cut loops in the stitch bar.
- Connect three barsput the door on and adjust the stitching beam.
Tip! Experienced craftsmen, when fixing the box, use pieces of cardboard or orgolite of the same thickness as pads. Thanks to this trick between the edge of the door and the box (bars), optimum gaps of 3-4 mm are provided. The main thing when using such a method is to fasten screws to control so that the wedges do not “dangle” in the box.
The most important part of the work at this stage is the insertion of fittings, the quality of which depends on the convenience of further operation of the door. A useful invention to help "homemade" are door goats - a device made of cardboard and pieces of wood that will hold the door in place.
Lock insert is performed sequentially:
- Check fit: insert the door into the box, then connect the hinge edge to the jamb and measure the gaps (from above, from the floor, on the sides). The gap with the floor should be no more than 4 mm, the remaining gaps - 2 mm. In case of discrepancy in dimensions, it is necessary to trim the edge of the door, which violates the recommended clearances;
- Mark sockets: draw a line across the looped end at a distance of 150 mm from the top, attach a loop by marking and mark the bottom edge of the part. Then you need to put gauge between the middle and the edge of the plate, draw a line from the front side along the end and connect both lines. After the main marking is applied, it is necessary to apply the size of the plate thickness and mark the place of the next loop, departing 225 cm from the bottom edge;
- Make indentations: take a chisel, put it bevelled, stepping back from the edge of 2 mm, and swipe with a mallet. It is necessary to cut the canvas to a depth that is equal to the thickness of the plate;
Useful advice: the chisel must be held at an angle of 45 across the groove and beat on the tool with sharp blows. After the desired depth is formed, it is recommended to install the chisel on the line vertically and trim the edges - cut the canvas from the top down and clean the grooves.
- Hang the door: first place the hinge in the upper slot, mark the hole for the screws and fix the hinges (see Hinges for interior doors: types and methods of installation). After that, you need to install the canvas in the box, knock down wedges and apply the markup on the joint. The last stage of work - fastening the hinge leaf with screws;
- Layout of the lock, spindle and keyhole at the end of the door. The height of the markup can be varied at its discretion, the main thing is to correctly dimension the lock on the front sides and mark the position of the well;
- Drill the holes for the well and the spindle, the slot for the lock, clean the socket and align the edges;
- Fixing the lock with screws, mounting the overlays for the handles and fixing the handles with screws.
The last stage of the inset of the lock - mounting the receiving lining:
- Close the door;
- Apply the marking of the position of the tongue on the joint;
- Hang the cover and measure the distance to the front side;
- The markup must be transferred to the joint, attach the pad and circle around the pencil.
The last stage of the work is to make a recess and screw the part to the joint. The slots under the latch and tongue are made with a chisel, after which you can fix the stoppers.
Step 2. Installing the box
Fix the upper part of the box with wedges, setting the wooden products at the level of the joint between the leg and the transverse part. To fix the bottom, you need to align the loop side and check the installation in two planes (vertically, horizontally) using a level.
Then fix the opposite side of the box and rigidly set the spacer against the lower wedges.
Step 3. Installing the web
At this stage, it is necessary to install interior doors with your own hands: hang a canvas and test the performance. The door should close evenly, without spontaneous closing / opening in the ajar position.
Before foaming the box, it is recommended to install additional spacers in the area of the upper loop and below the handle. Before installing the blade, it is necessary to clean and dust out the opening using a spray gun.
The last stage is the application of foam into the space of the box with the opening.

Note! Foam can damage the varnish of the door leaf, so before applying the composition it is recommended to glue the box with adhesive tape. In addition, during drying, the foam increases several times in volume, which must be taken into account when installing the canvas, exactly following the recommended clearances.
At this stage, every millimeter is important, as if the opening is reduced to less than 2 mm, for example, to 1.5 mm, the door will not close, and if it is in a big direction, the slot and part of the interior of the adjacent room will be visible. Since foam, depending on the type chosen, can “behave” differently, it is recommended to reduce the risk of side effects - significant squeezing of the box slats.
For this, experienced craftsmen apply a polyurethane composition as thin as possible. The time for complete drying of the foam is indicated on the bottle, after which you can gently remove the wedges or cut off the wooden products, remove the spacers and cut the protruding foam with a knife.
Step 4. Installation of additional elements

Additional elements need to be prepared: measure the distance to the wall with respect to the groove and trim the bar using a jigsaw or a hacksaw.
After that, it is necessary to insert the bar into the groove and replace it at several points. It is more difficult to install an interior door with your own hands if the standard width of the ledge does not allow to block the width of the opening. In this case, it is necessary to connect several additional elements using the interposer.
Шаг 5. Installation of platbands
The last stage of installation consists in the beautiful design of the opening on the sides and on top with decorative elements - platbands (see How to install the platbands on the door). After the installation of the interior doors with your own hands is completed and the foam has completely dried, firmly fixing the additional elements, you can proceed to the preparation of the trim:
- Determine the desired length;
- Saw a detail at an angle of 45 using a hacking saw;
- Drill holes with a diameter of 1.5 mm under the nails;
- Secure the part to the finish nails.
If you have to install the interior doors with your hands with a casing with a “beak”, then the installation process is simpler: you do not need to cut the part, just remove a part of the “beak” at the top, insert the product into the groove and fix it on liquid nails. Upon completion of installation, a threshold is set (see Thresholds for interior doors) - and the interior door is ready for operation.
