The interior door serves to divide the space in the room, and also provides sound insulation in a private house or apartment. In addition, the door leaf is an important detail of the interior, so it must match the style of decoration. Since installation works are quite expensive, the question arises of how to properly install the interior doors with your own hands. The answer is in the detailed step-by-step instructions on this page.
Dimensions and equipment
By the method of opening the doors are folding, sliding and swinging. The latter are the most popular, because structurally they are the simplest and fairly easy to install. They are presented in a large number of modifications. By the method of opening, the following are distinguished:
- bivalve and single leaf;
- left and right.
The most common sizes of interior doors are 710, 810, 910 and 1010 mm. Bivalves - 1340, 1540 and 1840 mm. The standard height of the doorway is 2055-2060 mm, but in fact it can differ upwards.
Of the basic materials you will need a door leaf, a box and platbands.
Of the accessories - hinges, handle, rotary lock and built-in lock mechanism. If the opening is deep (in the load-bearing wall), extras may be required.

Step-by-step installation of interior doors
How to install a single-door interior door so that it stands evenly and easily closes? The procedure is as follows:
- To dismantle the old door and prepare the opening.
- Assemble the door frame. The components must be laid out in the correct order, taking into account the direction in which the web will open.
- The upper bar of the box to connect with the ends of its two racks. You can use nails or screws.
- Install awnings.
- Install the box. The frame that was assembled earlier is placed in the aperture, and then put upright and horizontally using wedges.
- Hang a door. The hinge rack of the box must be fixed to the wall with screws, and then hang the canvas on the hinges.
- Secure the second post to the wall with screws. Then, on the sash, you need to check the gaps between the box and the edge of the canvas to prevent the formation of cracks. In a situation where a threshold is provided, it must be attached to the floor surface. Then foam mounting slots between the box and the edges of the opening.
- Insert a handle, lock and install platbands. Now we will analyze the technology of work taking into account the requirements of GOST and SNiP step by step.
Step 1: Assembling the door frame
A door frame is a frame made up of beams. Installation boxes can be made in a U-shaped or rectangular shape. The latter case is applicable when installing doors in the bathroom or toilet. The U-shaped form is usually used in all other cases when there is no threshold.
Cutting and connection methods
Manufacturers most often produce finished pieces for a box beam, which should be connected with each other with screws. If you plan independent work, then the best solution is to assemble the box according to the door leaf. To do this, the door is laid on a flat floor, after which the box parts are cut during the subsequent layout.
There are two ways to connect the details of the box:
- Washed down the lintels and racks at an angle of 45 °. For those who did not have much experience in carpentry, this method will be difficult to use. The parts themselves are connected using self-tapping screws. For them, you need to make holes perpendicular to the cut. Holes must be made in advance so as not to spoil the workpiece.
- He washed down at a right angle. To do this, it will be enough to use a hacksaw with small teeth. To determine the size of the bar vertically, you need to take the height of the canvas and add 3 mm to it to the bottom and top, provided that a threshold is planned in the doorway. If it is not there, you need to leave about 1 cm from the bottom. The ceiling will be fastened with two screws to a vertical stand.
It is important to remember - the second method is the only possible one in the case of sawing a bar for the threshold.
It is very important during installation to check all the gaps between the box and the canvas - there should be 3 mm on all sides. If a U-shaped box is installed, it is necessary to maintain a gap of 1 cm between the floor surface and the bottom edge of the door.
Connection box elements
All racks prepared in advance, as well as the upper crossbar, should eventually be combined and pulled together with 6 cm long self-tapping screws. At least 3 self-tapping screws should be used for one joint.
To achieve a normal connection density from one of the elements of the box, you need to remove part of the quarter using a chisel or a hacksaw. The length of the removed part should approximately equal the thickness of the bar that is adjacent to the part.
If the door size is much smaller than the opening, then installation should be carried out according to the following scheme with a lintel over the entire width of the opening.
Step 2: Install Loops
One of the most important steps in assembling an interior door at home is the installation of awnings. From these elements depends on how well the door will be closed and opened. Most people mistakenly believe that two hinges are enough when installing an interior door from MDF. But the most rational is the use of three pieces. Mark the location of the hinges from the top of the door.
You can use overhead or mortise loops. The entire installation process with photos and videos is detailed in the instructions for installing hinges on interior doors.
Step 3: Installing the box and hanging the web
The box must be installed in a pre-prepared opening. The stand with hinges must be aligned first with a plumb line or level. It is necessary to check it from all sides. Then the upper crossbar and the rack must be opened with wedges. The stand will be exposed only when it takes upright position.
Next, wedge the second rack. Be sure to check the horizontal part of the box.
The old way - side racks should be drilled through. To do this, holes for dowels are initially made in the wall. The box must be attached to the wall with self-tapping screws with a length of at least 150 mm.
In order to fix the box in the opening in a hidden way, you can use metal plates, which are usually used to install drywall structures. Most often, such plates are used together with anchors. In this case, it is worth choosing the number of fasteners in accordance with the expected load.
The use of such plates is a non-standard method and is possible only in the absence of a fine finish. It is recommended to grind a section of the wall in order to subsequently putty the fasteners.
It remains to hang the door on the frame. After that, you need to carry out the final adjustment of the box. Then the rack for the castle should be fitted under the door so that it does not protrude beyond the wall. It is worth remembering that to preserve the integrity of the box and the blade, you must first drill several holes for the screws.
Step 4: Foaming
After fixing the canvas, you need to foam the slots between the box and the edges of the opening. Foam should be fed gently, in layers, with the feed being made from above so that it does not protrude. Then the door will have to be closed and for a certain time not to touch it, so that the foam dries. The approximate drying time is 1 day.
If the composition accidentally gets on the canvas - immediately remove it with a clean, dry cloth, dried fragments are cleaned using effective methods of removing the mounting foam from the doors.
Step 5: Installing the lock and handles in the door leaf
The most popular today are handles with a built-in lock. The procedure is as follows:
- Mark a meter from the floor. The handle mechanism must be applied so that a mark is visible from above in the hole.
- Drill holes in the blade from the end. After that, the edges of the holes should be cut off with a chisel to even the hole.
- Insert the mechanism into the hole. In this case, the lock must be aligned, and then fixed with self-tapping screws. The lock should be encircled with a pencil to cut veneer, then the mechanism should be removed. According to the intended contour, you need to select a site for determining the thickness of the keyhole. This is done using a chisel.
- Drill holes for latches and handles. It is necessary to attach the lock to the canvas from different sides, align it and mark it. The holes should be made on both sides and at the same time they should not be through.
- Remove the resulting chips and install the handles.
It is important to remember that you should not use the screws that come with the handle in the kit. They are made of non-solid metal, as a result of which they quickly fail. It is worth using high-quality red-hot self-tapping screws. Read detailed step-by-step instructions for installing the lock and handle in the interior door.
Step 6: Installing Trims
An extension is a strip about 2 meters long, 250 mm wide, and no more than 3 cm thick. The strip should be used during the installation of interior doors if the wall is thicker than the door frame.
The beam for the box is made in a standard width of about 70 mm. It can be expanded according to the thickness of the opening by adding. This will more clearly combine the box and the walls. On a bar there is a groove for a level. First you need to measure the distance to the edge of the wall, starting from the depth of the groove.
The add-on can be installed in various ways:
- in the groove in the box;
- with groove cutting in the absence of finished;
- attaching the extension from the inside of the beam in the absence of a groove, the box is installed with the extension;
- fastening of the good in the form of "P";
- if the extension is not too wide and there is no groove in the box, the bar should be drilled and screwed to the box.
The plank is sawn into several parts with a circular to get several add-ons of the required dimensions. You need to cook one short bar and two vertical ones. Read our simple step-by-step instructions for installing additional doors on the interior door.
Step 7: Fixing the platbands
During installation of platbands, the box should be located at a level with an opening on the front side. To connect the platbands, you must first attach the vertical bar to the box and put a mark higher by 0.5 cm, stepping back from the crossbar of the box. This mark will act as the edge for the cut. In the same way, you need to mark the slice on the other side.
Joints in platbands should be sawed at an angle of 45 degrees. when using a miter box. You can fix the platband to the box when using nails that do not have hats. Read more about installing platbands on the interior door.
