How to install frame and door. We install the door frame with our own hands. Fastening doors using Knauf hangers
Sections of the article:
Usually, when the renovation is already completed, homeowners can only purchase and install interior doors. Some people trust installation door block professionals, others are used to doing everything themselves. For both the first and second categories, we will tell you how to install a door without mistakes.
The installation process is not complicated, but painstaking - it is important to accurately set door frame. However, if desired, any home craftsman can do the job.
Brief description of the technology
The installation is carried out sequentially and consists of several steps. At the first stage, you should measure the doorway and purchase a door block. Then you need to prepare the opening. After this, all the fittings are installed on the door - these are hinges and latches. Next, the box is assembled and additional strips are installed if necessary. Then the door is connected to the frame and placed in the opening. After this, all that remains is to fix the structure and install decorative elements.
If you don’t know how to install an interior door, experienced craftsmen will share tips and show you the door installation process step by step - you just need to watch a specialized video that shows all the details. You can see it at the end of this article.
Necessary tool
To work you need a tool. First of all, a hammer and chisels. To take measurements, you should prepare a tape measure. If you are dismantling the old door, then you will need a crowbar. Also, it will not be superfluous to have a wort and a power tool - a drill or a hammer drill.
Preparing the opening
If after repair there is still old door it needs to be dismantled. To do this, it is recommended to use a crowbar - dismantling work should be done as carefully as possible. First of all, decorative elements are removed, then the canvas and box parts.
Often, during the construction of houses, builders cemented door frames - to dismantle them in this case, you need to work with a hammer.
To facilitate installation, it is recommended to prepare the slopes - they are leveled and plastered. The final stage preparatory work is cleaning - the site of future installation is cleaned of dirt and dust. If the apartment and the opening are new, then you can skip this stage and go straight to taking measurements.
Measurements
In order to choose the right door, it is advisable to know the parameters of the height and width of the opening; the size of the slope is of no small importance. Often, the edges of the opening are not very smooth, so measurements are taken at several points and the smallest one is selected.
Experts recommend that you take into account the gap between the door blocks and the opening. Before installing the door, the final floor covering must be completely laid. But if it doesn’t exist yet, then the dimensions include the height of the future covering - it is usually laid in the doorway.
Preparing the place for the lock and hinges
Before starting the process of assembling the box, the areas where the locks and hinges will be attached are marked and treated with a chisel. To do this, lay the door in a vertical position.
First of all, apply a lock to the canvas and use a pencil and tape measure to mark approximately 900 mm from the floor - this is standard height for most interior doors. The hinges should be installed 200 mm from the edges of the canvas. The loops are also attached, and the place under them is processed with a chisel. This must be done so that the loop and lock lie flush on the surface of the canvas. Next, using a drill, drill holes and screw in self-tapping screws.
The vertical stand is applied to the canvas so that there is a small gap of 2-3 mm. It should be between the horizontal crossbar on the frame and the door leaf. Next, mark the place where the hinges are attached to the box and also select a place for them.
Not everyone knows how to insert a door using technology and some of the subtleties of this process. Experts recommend treating protective varnishes places that are prepared for the installation of a lock and hinges. By using varnish coating the wood will be reliably protected from moisture. Do not forget that interior doors are installed on two hinges, while entrance doors are installed on three.
Installation of locks and hinges
Now let's see how to insert a lock and hinges into an interior door. The locations for these fittings have already been selected - all that remains is to secure them. But this is only relevant for loops.
Installing a lock may require some effort from the technician. In order for the latch to fit correctly on the leaf, it must be applied to the side surface of the door and the locations for handles, fittings and fastening points must be marked. Using the same chisel, the installation locations are again selected. Then, the lock is installed and screwed using self-tapping screws.
There is small nuance. When selecting a latch or lock, you need to take into account the width of the door frame. The hole for the lock should not be more deep than a third of the width of the block. In any other case, the door leaf is simply deformed.
Door frame assembly
Before assembly, you need to measure the height vertical racks. Next, they are trimmed using a miter box. The horizontal beam is adjusted to the width of the door leaf.
Since assembling the door block requires a lot of free space, the process itself is best done on the floor. To ensure that the finish of the box is not damaged during assembly, slats the length of the canvas are placed in the places where the racks will be laid.
The horizontal crossbar is applied to the racks. It is better to tap the places where the planks will be connected with a hammer - this will improve the connections. Next, the box is fixed using a screwdriver or screwdriver. Self-tapping screws are screwed into joints and corners.
Some door models are sold with the frame already fully assembled. Installing doors of this type on your own turns into the simplest possible process - the frame is simply placed in doorway, and then fixed.
Installation and fastening of accessories
How to install a door correctly if the width of the door leaf is a couple of centimeters less than the slope? In your case, additional strips will help you. In some situations you can do without them, but in this case you will have to additionally “build up” the slopes. But this takes time, and in the process further exploitation chips appear, and, accordingly, dirt. Extras in this situation are the best and easiest way out of the situation.
As additional strips, door installation experts recommend using products that match the color of the door. Their thickness can vary - from 8 to 12 mm. When the extensions are fixed, they form something like a portal. Their edges coincide with the edge of the wall.
Installation of the planks is extremely simple. So, using a chisel in the box you need to select a quarter. Its size, depending on the additional strip, can be 10x10 or 8x8. This is done along the entire outer perimeter of the box. The slats must be cut exactly to the height of the box. The horizontal trim is also cut to the width of the box.
The installation of the elements is carried out after the box is installed in its place in the opening and fixed. Next, additional trim strips are mounted on the selected quarters and secured with dowels or self-tapping screws.
Installation of the box in the opening
So, after assembling the box is finished, it’s time to start installing it in the doorway. To do this, the block is inserted directly into the opening and fixed using wedges. Experts recommend inserting no more than 2-3 for each vertical post and 2 wedges for the top crossbar.
Then the box is aligned along the vertical and horizontal axis. The tilt adjustment process is easy to do by hitting the wedges with a hammer. After the door block fits perfectly, the frame is secured. Using a drill or hammer drill, a hole is drilled in the box and wall. Using dowels, the frame is installed in the opening.
Installation of the canvas
When the frame is level and secured, it's time to move on to installing the door leaf. First, the hinges are screwed onto the door. Most often, detachable hinges are offered for interior doors, which have a rod that can be removed or fixed in a hinge. One-piece hinges are also sold, but they are now practically not used.
If hinges with an embedded core are used, then everything is very simple - the canvas can be easily put on and removed from the box. To do this, you just need to carefully lift the door to a small height.
If it does not rise (and on some door models this is really not easy to do), then a one-piece type of hinges and a removable rod are used. To install these types of hinges, they are also secured with self-tapping screws on the frame, and then screwed to the door leaf. If the rod can be pulled out of the hinge, then it is simply removed and the blade is removed.
When the hinges are installed, you can proceed to hanging the canvas. It is better to perform this operation not on your own, but with someone’s help. One person will hold the canvas, the second will install permanent hinges or guide the canvas into place (if the hinge is collapsible).
When choosing hinges, you need to remember the opening side, otherwise, at best, you will have to replace them in the store, and at worst, waste time installing the hinges.
Fixing the door frame
The next step in how to install an interior door is to secure the frame. The gap that exists between the opening and the door frame is usually filled with polyurethane foam. This is done to fix the door block and increase sound and heat insulation. Polyurethane foam perfectly fills even the smallest defects, crevices and cracks. This material is easy to use and goes well with any type of surface.
Before filling the gap, you must close the box to prevent foam from getting on it. To do this, it can be covered with masking or construction tape, or film. If a little foam has already gotten onto the surface of the box, then while it is fresh it can easily be washed off with solvents or alcohol. If the foam has already hardened, then removing it in this state can be quite difficult - this is only possible mechanically, which entails inevitable scratches.
One of the properties of foam is that it can expand significantly in size. This must be taken into account when applying. Sometimes it happens that the door frame simply becomes deformed - this happens to those who do not know how to correctly insert the door frame and interior door. To prevent this from happening, cardboard spacers are usually used. They are installed between vertical posts. Thick cardboard can also be placed between the closed opening and the box.
To prevent distortions of the box, foam is applied in two stages. At the first stage, spot application. Then, after cooling, fill in whatever is left. Excess material is cut off with a sharp knife.
Next, all that remains is to install the trim and fittings. To do this, they are cut to the height of the box at an angle of 45° for horizontal and universal strips. Fastening can be done with nails or glue.
Here's how to install an interior door or any other door with your own hands. Our detailed instructions will help home handyman, and in the video you can watch the entire installation process from A to Z.
Doors, despite their apparent simplicity, are very demanding to install. The slightest mistake can lead to disastrous consequences. Incorrectly taken dimensions or cuts made will be impossible to correct, and you will have to do everything all over again using other materials. Cracks formed due to an erroneous sawing cannot be eliminated using sealant.
Even if this disguises external defects, the structure will not be strong due to a loose fit to the surface. As a result, the load on the bars increases significantly, and the service life of the door is reduced. In order to prevent such a situation, it is necessary to assemble the door frame with your own hands, strictly following the step-by-step instructions. It is important not only to perform all installation work correctly, but also to carry out all installation work very carefully and accurately.
The frame base must match the door parameters (width and height) in order to provide full coverage and support to the structure. An important nuance relative to the canvas is the purpose of the room for which it is intended. Because ventilation requirements will depend on this. In steam rooms and baths, doors must provide reliable thermal insulation, so the opening is sealed as tightly as possible.
The bathroom, on the contrary, needs to be well ventilated so that excess moisture does not accumulate and mold does not appear. Therefore, the gap between the frame and the door should be a little wider. Good ventilation is also required for rooms in which gas equipment is installed.
To provide reliable protection to prevent heat leakage, a rectangular frame is constructed from four bars, which will serve as a frame for the door. The vertical posts will become hinged and recessed elements, and the transverse ones will become the upper support and threshold.
For free movement of the door leaf, the gap between the door and the posts should be about 3 mm. In cases where air flow into the room is necessary, the box is assembled from three bars, and a gap of about 10–15 mm is made at the threshold site. A standard distance of 3 mm is left along the vertical posts and the lintel.
The box with the threshold assembly is slightly higher than without it. The difference is about 20 mm. It is important to take this nuance into account so that you do not have to shorten the door. Because it is possible to adjust the canvas only if it is made of wood.
The gap between the door frame and the opening must be at least 10 mm on each side so that the structure can be easily installed and fixed.
Required Tools
The door frame can be installed with your own hands using various instruments, many owners have some of them, but what is missing will have to be rented or purchased.
- Miter box. A device that allows you to cut timber at different angles.
- Pencil, tape measure, construction tape.
- Acrylic paint on wood.
- Polyurethane foam for sealing the box.
- Chisel for making cuts for hinges.
- Hammer, drill, screwdriver.
- Nail puller, crowbar, hammer. For dismantling work.
- Miter saw, hacksaw and utility knife.
- Building level.
Dismantling
If the doors are not installed in a new room, but the structure is being replaced. Then you can install the door frame yourself only after the old one has been removed. The door frame is dismantled in the following order:
- The platbands are removed and the elements of the box are disassembled.
- Fasteners and anchor bolts are unscrewed.
- The strength of the opening is checked and, if necessary, it is strengthened.
It is worth disassembling the door frame very carefully so as not to damage anything and thereby increase the amount of installation work in the future. If it is necessary to replace the door frame, it is recommended to dismantle it in advance so that there is time to prepare the opening. It is almost impossible to remove the door frame without damaging it. Therefore, after removing old components, you will need to install new ones.
How to assemble a door frame?
The assembly diagram will help you make a door frame from blanks correctly.
The box must be enlarged with the help of extensions if the width of the wall is more than 70 mm, and platbands are installed on both sides.
If you are assembling a door frame from MDF, everything fastening work must be carried out with preliminary drilling to prevent cracks and chips from forming on the product.
How to file a door frame at 45 degrees?
Elements with a round cross-section are sawn at an angle of 45◦. In order to make the correct cut, use a miter box or miter saw with a rotating table.
You can assemble door frames with your own hands without using special tools. In such cases, you can saw off the desired angle without a miter box, using a ruler and a protractor for marking.
During installation, the structure is secured using self-tapping screws, which are screwed in at an angle.
Assembling the box at an angle of 90 degrees
With this option, assembling the door frame is easy and quick.
- It is necessary to saw off the required size of the racks and the horizontal crossbar at a right angle.
- Select the extra part of the vestibule.
- Place the box elements on the floor, level them and secure them at the ends with self-tapping screws (2 each).
In order for all sides to remain parallel to the door frame, you can attach the door and check how it will stand in the opening. Specialists consider connecting the door frame at 90 degrees fast technology installation
Assembling a box with a threshold
There is no significant difference between installing door frames with and without a threshold. Rapids in Lately have lost their relevance. But despite this, such a system has many fans. This is explained by the fact that it is stronger and more reliable than a structure without a lower cross bar. Such systems can withstand significant loads and are suitable for installing solid wooden doors. Thresholds are considered prerequisite for bathrooms. Regardless of what type of design is chosen, assemble the box interior door every person can.
- Vertical and horizontal planks are prepared in advance.
- Cut at 45 or 90 degrees.
- The prepared elements are placed on a flat surface.
- The racks and crossbars are alternately fastened using self-tapping screws.
How to install a door frame correctly?
The door frame is installed after preliminary checking that it matches the dimensions of the opening in the wall.
- If everything is suitable, the door frame is installed in the opening.
- Using a hydraulic level, check the verticality of the racks and the horizontality of the crossbars.
- Wedges (about 15 pieces) are installed along the entire perimeter of the structure. Door frame spacers add strength.
- Make markings for attachment points. Holes are drilled along it on the bars and walls. Many experts attach the door frame to the wall in the places where the hinges and the lock strike plate are located. This allows you not to violate the integrity and appearance products.
- The door frame is fastened anchor bolts, which are inserted into the holes and tightened with a screwdriver or wrench(depending on the type of fastener). The structure should be fastened very carefully.
- Screw on the hinges and hang the canvas. At correct installation opening and closing the door will be easy.
- The gap between the block and the wall is filled with polyurethane foam.
Reply metal strip the lock is installed on different stages: during assembly or when the structure is already fixed. The second method will be more correct and accurate.
- Cover the doors and mark the location of the tongue or magnet with a pencil.
- Use a chisel or a feather drill to make the required hole. You don't need it to be too deep, the main thing is that the tongue fits and holds the door.
- A sample is made according to the size of the counterplate and installed, securing it with self-tapping screws. There is no need to mount the element very deeply, this will spoil the appearance.
- The gaps are filled with sealant.
What else is important to know?
Not every person will be able to install a door frame efficiently the first time. But don't despair. Because many flaws can be eliminated.
- If there is an unsightly seam, you can close the joint between the laminate and the door frame with a plinth or a special flexible threshold.
- If the box does not fit into the opening, then the posts and crossbars can be trimmed a little.
- Platbands allow you to beautifully seal the gap between the door frame and the wall. If their width is not enough, you will have to plaster and decorate the gap.
- To install an interior door frame in concrete wall or made of brick, it is impossible to do without a hammer drill. If you are installing a door frame made of MDF first on the slats, use a drill to make holes and only then work with a hammer drill.
- Attach the door frame to wooden wall much easier than other materials. In this case, a hammer drill for drilling holes is not useful. You just need to screw the door frame to the wall using anchors. The main thing to consider is that over time wooden buildings may cause significant shrinkage.
- To facilitate the installation process, special installation systems for door frames were created. Thanks to them, the structure can be placed in walls made of any material without using wedges and spacers. This kit includes hidden mounting fasteners, detailed step-by-step instructions and diagrams. Using the system, even a beginner can insert a door frame.
Having bought a door frame in a store, you should not immediately despair when you see a large number of prefabricated elements. To assemble such a structure, you do not need to be a specialist with higher education. To assemble a door frame with your own hands, we will consider the entire installation process in detail.
Typically, interior doors are sold disassembled, and what we see at first glance is an incomprehensible and chaotic set of elements, which includes a profile wooden beam, in the worst case, from MDF, locks and awnings, as well as canvas. All this vaguely resembles the children's designer from the “do it yourself” series, and most people, seeing all this, panic and begin to look for a specialist experienced in this field, whose services are not very cheap. Other enthusiasts are still trying to solve this puzzle, but their efforts run into a big question mark, because without detailed instructions It is very difficult to understand the assembly process. In this article we will try to help you figure out how to do without outside help assemble the door frame.
Determining box dimensions
The first and very important stage The entire assembly process involves an accurate calculation, down to the millimeter, of the length of the sill posts, the threshold (if any) and the upper lintel.
Measuring the racks
The height of the racks should be equal to the height of the door. Typically, the standard door height is 2000 mm. Having made sure of this, we add the width of the gap between the door leaf and the door by 2-3 mm to the height of the door leaf. When installing doors with a threshold, the width of two gaps of 3 mm each must be added to the height of the door leaf, for a total of 6 mm. In the version without a threshold, we add only one gap measuring 3 mm, and add 1 cm at the bottom so that the door leaf does not cling to the floor when opening and closing the doors.
As a result of accurate measurements we get following parameters: with the option with a threshold, the height of the doors and pillars will be equal to 2000 mm + 2 gaps of 3 mm each = 2006 mm; with the option without a threshold, the height of the doors and pillars will be equal to 2000 mm + 3 mm + 10 mm of clearance = 2019 mm.
Measuring the threshold and upper jumper
The size of the threshold and the upper lintel of the door frame must be the same. Let us correctly determine their length, which will be equal to the sum of the width of the door leaf, the width of the gaps between the door and the door and the thickness of the profile beam from which the door will be assembled.
In addition, on both sides of the lintel and threshold sections, it is necessary to cut out landing sections, that is, cut off the protruding parts of the opening into which the door rests when closing. The cut should be equal to the thickness of the post at its widest point.
To correctly cut the samples, measure the thickness of the rack on both sides from the edge of the lintel and carefully cut it with a small hacksaw.
After this, you can screw up the door frame with a calm heart.
Do-it-yourself door frame assembly
We screw together the door frame using self-tapping screws or confirmations for wood over 55 mm long. To prevent the profile beam or MDF from cracking, you must first make holes with a slightly smaller diameter than the screw-in screw, approximately 2-3 mm.
To ensure that the structure holds tightly and does not fall apart during installation, all joints must be secured with self-tapping screws at least twice.
Marking and inserting canopies
The final stage of door installation is connecting the leaf to the door frame. With the help of a simple operation this will not be difficult. Having placed the door frame on the floor, you need to place the door leaf with the canopies embedded into it.
Place the leaf in the door frame so that the gap is the same on all sides and equal to 3 mm. To do this, you can use a school ruler, the thickness of which is just 3 mm.
After the door in the frame is aligned, you need to copy the location of the canopies from the doors to the door using a marker.
Pull the doors off the frame, place it on its side and use a chisel or router to cut out seats for awnings.
Connect the doors with the frame into a single structure and screw the hinges to the door.
The door frame assembly is complete. Now the entire structure is ready for installation, and you can confidently say that you have completed the DIY door frame puzzle!
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 the interior door, the old one must 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 of both the door leaf and frame is different. The door leaf is:
- From fiberboard. These are the cheapest doors. Represent wooden frame, to which it is attached laminated fibreboard. 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 standard sizes, it’s just a pity that the standards are different countries are different. For example, in our country swing doors made with a width of 600 - 900 mm in increments 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 put 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 the door block you need. 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 full set interior door - 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 an assembled door block, the first thing you will have to do is assemble the 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 during wet areas. For the bathroom, definitely leave a little more, otherwise in high humidity they may have difficulty opening.
So, we have decided on the minimum 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 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 side opposite side and from above. Having set these gaps, the canvas is fixed using wedges. Positioned exactly horizontally 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's counterpart. 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 with 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 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 ( exact time indicated on the cylinder), remove the spacers, hang the door leaf and check the operation of the door. 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.
Doors are installed after the apartment renovation is completed, but before, as is customary. But if you just decided to replace it with a new one, this article will also be interesting to you. The cost of the door block depends on the configuration and size, if purchased full set a finished frame + door leaf + fittings, such a door will cost more and you may have to tinker with fitting the frame into the opening. If you decide to install an interior door yourself, we will do it correctly so as not to waste money and time.
How to install an interior door
Main door frame Basic structure with which to start assembly, then you need to cut in and install door fittings, after which you can secure the box in the doorway, hang the door leaf and finally close the box with platbands. That's the plan, let's go!
Door frame design
Depending on the size of the doorway, the door leaf and frame are selected. The width of the box depends on the thickness of the wall, in panel houses The wall thickness is 130 mm and, accordingly, the box should be the same width (excluding platbands). In the store or on construction market You can purchase a box from 80 to 220 mm, you can easily find the size that suits you. In the table you will find the door size corresponding to your opening; 
If you don’t find a door frame of a suitable width, you can extend the frame with extensions.
Not so long ago, ready-made wrap-around telescopic door frames appeared; installation of such a door is much easier if you are installing doors with your own hands for the first time - I recommend it. 
Installing a threshold in an interior door frame is not at all necessary; most often, interior doors are installed in a U-shaped frame consisting of a hinge post, a ceiling beam, and a door post. Complete door frame complements bottom beam or threshold.
When calculating the dimensions of doors and frames, do not forget:
- Clearance for polyurethane foam must be at least 10 mm;
- Gap between door leaf and a box of 3-5 mm on each side;
- For an equal floor (tile, laminate, linoleum) the gap between the floor and the door is 5-10 mm, for carpet or carpet - 15 mm;
- If the size of the doorway is insufficient, it will have to be expanded using a hammer drill;
- If the door frame is smaller than the opening, you can fill the voids with strips of drywall or plywood;
Door frame assembly
Before installation, the box is sawn to the size of the opening and assembled. You can file the joints at an angle of 45 degrees (if there are any Miter saw).
Or at an angle of 90 degrees, this is an easier way, but here it’s also a good idea to use a miter box and the old rule “Measure twice, cut once!”
It is convenient to assemble the box on a flat, level surface. We screw the lintel beam to the posts with self-tapping screws, 2-3 on each side. The joints can be glued with PVA glue and then tightened with screws.
Assembling a door frame is not difficult; watch a special video about the process of assembling a door frame, which shows everything in detail.

5 rules before going to the store
There are several rules that I try to adhere to before going to the store for tools or spare parts: 
- 1) — Make a shopping list so that you don’t forget anything and don’t buy too much.
- 2) — Take a photo of the unit being repaired or the assembled spare part, a nameplate with markings if there is one. This makes it easier to explain to the seller, show the photo and he will immediately understand you.
- 3) - Take exact measurements, do not trust “measurements by eye”.
- 4) - Do not buy “for future use”; such purchases usually gather dust in the pantry or garage, and if they break down again, they cannot be found and you have to buy them again.
- 5) - Do not buy used tools or spare parts, no one knows how long they will last and who knows, perhaps the “unheard of cheap” electric drill was stolen. As you know, free is only in a mousetrap.
