Do it yourself plastic windows repair

Today production plastic windows engaged in a huge number of companies. And with such competition, it is obvious that the products should be of the highest quality possible. Despite this, even high-quality PVC windows begin to loosen over time and require adjustment, and sometimes even repair. And to save yourself from unnecessary costs, you can repair PVC windows with your own hands.

Required Tools

In order to carry out almost any window repair, you may need the appropriate tools and accessories. Their list can be briefly described as follows:

Means WD-40.
Pliers.
Crosshead screwdriver.
A complete set of star-shaped screwdriver bits.
4 mm Allen key.

One of the most important elements for repairing and adjusting PVC windows is a hex key, which is often made in the shape of the letter “G”. It is he who is suitable for most of the popular windows installed in homes.

Plastic window handle repair

Often there are problems that relate specifically to window handles. You can highlight the most common:

backlash of the handle;
jamming;
seizure
complete failure.

In the case of backlash, everything is not so scary. In order to forget about the existence of this problem, you just need to tighten the appropriate mount a little.

Such a task is performed as follows:

Locate a squared underlay under the handle.
Pry it and rotate it 90 degrees to the side.
Before you are two bolts, which should be tightened properly.
Take a Phillips screwdriver and do the necessary work.
Hide the whole mechanism. Work is done.

If such a nuisance occurs that the handle on your PVC window or door breaks, you have to replace it. The work is carried out in this way:

Place the handle in the open position.
Rotate the rectangular pad 90 degrees.
Turn away bolts which you will see under an overlay.
Remove the broken old handle.
Install the new item in reverse order.

If you suddenly notice a jam on the handle on the windows, or the fact that it does not reach the end of its position, this can mean different problems. Here are the most obvious:

the need for cleaning and good lubrication;
the need to loosen the pressure on the wings.

You need to slightly loosen the handle on the wings, disassembling it according to the scheme described above. If this does not help, then dismantle the handle, take a vacuum cleaner or brush, and clean the entire mechanism from contamination. Process everything, then grease with machine oil. You can, of course, use the well-known WD-40, especially since its handset is very convenient for our problem.

When you notice that the handle of your window has simply jammed, this could mean such problems:

Frost. From squeezing the structure in the cold, the blocker could lead to such a nuisance.
Sharp movements when using the handle.

In order to fix the problem, you need to adjust the special sash on the side of the window so that it is in an even vertical position. So you can resume the normal operation of the pen. Check if the sash comes into place freely when closing the window. If not, you need to slightly adjust the mechanism with a screwdriver. It is not difficult, and you will surely cope with such a task.

Repair of plastic window fittings

Often, the main problems that suggest thoughts about changing windows are their fittings. She begins to close poorly, miss third-party sounds, or even worse - cold. Therefore, repair of the mechanism of plastic windows is also a very topical issue.

Repair plastic windows yourself

To begin with, it should be said that every year it is necessary to carry out preventive checks of windows in order to avoid possible breakdowns. This is especially true of our country, because the temperature in winter is almost critical, and in the summer it is incredibly high. Performing the test, the voltage in the accessories will be reduced, and the result will be a long service life.

Solving the problem is quite feasible with your own hands, especially since the prices for repairing PVC windows really bite.

Getting started:

Find the oval cylinders that are located at the ends of the sash. These are trunnions or eccentrics, to whom it is more convenient.
On the frame itself, you will find reciprocal hooks, created with the aim of the sash coming in and when turning the handle, pressed against the frame itself.
In order to perfectly adjust the mechanism, you need to scroll the eccentrics or move the reciprocal hooks, and then perform the check.

If your task is to adjust the correct closing of the sash, the procedure is as follows:

Find the protruding part of the cam.
Turn it so that the process goes towards the insides of the window, if it needs to be tightened. Accordingly, if necessary weakening - turn in the opposite direction.

Varieties of Eccentrics

When repairing and adjusting plastic windows, you may find that the trunnions will not look the way you expected them to be. This is simply explained: at different manufacturers this element can be regulated in different ways. The most popular adjustment methods are as follows:

turning the eccentric with pliers;
the eccentric is retracted from the end surface, after which it scrolls a little. To retract the axle, you can use pliers;
turning the slot with a flat screwdriver, which is on the pin.

Make all adjustments very carefully so as not to accidentally damage the mechanism.

Work with a mate

Such a surprise may occur that the cylinders will not lend themselves to tuning. This does not matter, and there is a way out of this situation.

In this case, you will need to take a hex key, which should correct the reciprocal part of the mechanism. It is fastened with two bolts, and if you loosen them, the hook will be free for easy movement. Naturally, to carry out such adjustment and repair of plastic windows, the photo will help you like nothing else.

Setting up the side with awnings

If you have installed windows that have a ventilation mode, and this is exactly the problem, there is also a certain procedure that will allow for high-quality repair of PVC plastic windows.

Remove the so-called platband cap, which is made of plastic. It is located on the lower canopy.
In the canopy you need to find 3 bolts. 2 of them will be visible, and one is a little hidden.
The hidden bolt is adjusted with a hex wrench, and with it, it is possible to adjust the position of the sash relative to the frame.
If you need to adjust the clamping force, you will need to adjust the bolt, which is perpendicular to the plane of the window itself. Adjust it when the sash is in the closed position.
Turn the key clockwise to increase the pressure, or counterclockwise to release it.

As for the upper part of the sash, its fastening is carried out not on the canopy, but on the so-called scissors. To adjust it, follow these steps:

Open the sash.
At the side you can see the clip of the lock, or a special lever. You must click on it.
While the lock is in the clamped position, you should turn the window handle to the airing position.
You will notice that the leaf has come out of a special groove, after which it will harden in a hanging position on the scissor mechanism.
You got to the head, which adjusts the sash pressure on top.
Turning the head of the bolt, you can adjust the clamping force. Take small turns.

Warm slopes on the windows

When the repair of plastic window locks is over, you can think about other problems and difficulties that most people inevitably encounter, who at one time decided to install PVC windows.

So now it's time to talk about repairing the slopes of plastic windows. Often, standard slopes are not the best choice, so they need to be insulated.

Installation reason

There are some of the most urgent reasons why people decide to install new slopes or repair old ones on their plastic windows:

Extension of window service life (in some cases up to 20 years).
Avoid darkening.
Reinsurance against fading windows.

When slopes are installed

People who are involved in the repair and installation of plastic windows know how long it takes to properly install the windows, as well as carry out the installation procedure of the slopes. But we will highlight this point in more detail.

One day will be quite enough for the windows to "infuse" after installation. After this, the window sill is placed. Providing for its installation, you need to think about the fact that plastic is able to expand from temperature extremes. Therefore, on the left and right sides, it is necessary to leave gaps of at least 1 centimeter.

By the way, you need to take care of the back of the future window sill, because it must withstand heavy weight. It is possible that during the operation of the windowsill, which can last for decades, it will be stepped on more than once with the goal of washing windows, hanging curtains, curtains, etc. Therefore, the window sill is installed between the supporting screws, as well as part of the profile from the bottom. So you can achieve free withstand loads of up to 100 kg at any point.

Another useful tip regarding a windowsill relates to its tilt. Any window sill should be slightly tilted into the room. This is because otherwise, moisture will collect near the window, and this will inevitably lead to the appearance of fungus, mold and other troubles.

Installation of slopes

The installation of the slopes can begin. Here is a list of necessary operations:

Drill through the wooden guide holes. The drill is necessary at 6 mm, and the depth of the holes should be from 50 to 120 mm.
Insert the dowel and 51 mm self-tapping screw there.
Tighten all the screws, and also install the caps to the middle of the rail.
Now, if you need to press or take the rail to the slope, you can simply twist the self-tapping screws, which have become adjusting.
Align all the guides parallel to the frame itself. By the way, special devices are not needed for this, even a specialist for repair and maintenance of plastic windows will tell you this. You can do the assessment of the visual appearance. Explaining this need is very simple. Often, windows are installed with a slight tilt specially. And if the windows in your house fall under the list of such, exactly installed slopes will only emphasize their unevenness, and outwardly it will be more than noticeable.
Lay the wedges under the rail, and then fill in the mounting foam. So you can fix the rails. By the way, the choice is best made in favor of summer foam, because it has more firming properties.
If you decide to install plastic slopes, they need to be wound around the frame by about 3-6 millimeters.
Next, plaster the foam seam. If suddenly the plaster gets on the frame, do not worry, because after it dries, you can easily remove it.
The next step is to nail the J-profile on the guides, which will serve as the connecting one. To fix it, you will need to drive the brackets, about 1-1.5 cm. Choose a step from 10 to 25 centimeters.
In turn, in order for the C-profile to lie perfectly, the wall must be worked out with a gypsum mixture, which quickly hardens.
Next is the formation of the foam seam. This is one of the most important points in the repair of slopes, so you need to be careful. Apply foam evenly. Form a foamy seam, filling about 10-20 percent of the underfoot surface.
Warm the slopes with mineral wool, which also absorbs excess moisture. This is the way you will get rid of the possibility of a fungus.
Now you need to press the panels to the rails, and then fix them with an electric stapler. By the way, if you beat the staples of the stapler at an angle, they will create additional pressure by pressing the panel more reliably.
Clean the plaster with a spatula.
Insert the corner of the C-profile with a part of the internal type lock, then snap it into the hook of the J-profile.
After this, the corners must be sawed with a hacksaw. This will make the seam invisible.
Everything is almost ready for applying decorative sealant. It remains to clean the room and the plastic elements of the window.
Degrease joints with suitable means.
Moisten the joints with water.
Apply a sealant to perfectly clean windows, which will cover all existing joints.

As you can see, the work is not easy, but if you know that the cost for repairing PVC windows by firms is not very low, you can master such a small improvement yourself, especially since the manual explains more than in detail.

Repair of plastic windows. Video

Concluding the conversation about window repair, I want to back up all the described operations with a wonderful video tutorial. It contains tips for repairing the most popular problems that arise with most models of PVC windows.

PVC windows in the house - it is very convenient, comfortable, and warm. A high-quality plastic glass unit will serve for a long time, but, unfortunately, even a high-quality profile of a trusted manufacturer needs preventive repair over time.

In order not to spend money on installing a new window (except when it is really necessary), you can easily repair plastic windows with your own hands. In solving the most common problems with PVC windows, video instructions on the Internet will help.

To deal with malfunctions of the PVC window, you need a minimum of tools that every owner has available:

Phillips and flat head screwdrivers;
A set of nozzles for a screwdriver - "stars";
The key is a 4mm hexagon, it is also used for furniture repair and assembly;
Pliers;
Engine oil or grease WD-40

Window Adjustment Points

To make the repair of plastic windows with your own hands, you need to understand their device. Almost all PVC windows installed in apartments have three adjustment planes, thanks to which the window part is in an optimal position relative to the frame and provides good contact with the rubber seal. The whole thing is in the hinges: the lower one determines the vertical position of the sash, the upper part of the window sash is responsible for adjusting the upper hinge, and the clowns affect the degree of pressure.

How to adjust PVC windows

A common problem is the displacement of the mechanism, due to which the wings begin to bury and open incorrectly. Sagging occurs when the window touches the frame, and at some point this will cause the window to stop functioning normally. To adjust and return the PVC windows to their normal position, you will need a 4 mm hexagon.

Skew elimination

When repairing windows, it is important to consider that they must be open at this time.
The top of any window is adjustable. If there is a skew of the window in the top-bottom position, regulation is performed by pulling the bottom loop. To adjust the leaflet height up or down, you need to remove the plastic trim from the bottom hinge and insert the hexagon into the adjustment groove on top of it. When the hexagon is turned clockwise, the window sash will rise, on the contrary, it will lower.

To adjust the sash to the left or right side, you should also use the bottom loop. At the same time, the key is inserted into its lower groove; when the hexagon is turned clockwise, the sash moves to the left side, counterclockwise - to the right.

The upper part of the window is tightened with the help of an adjusting element located in the very upper part of the sash near the hinge. Similarly, adjusting the lower loop, using the hexagon, there is a correction of the skew left or right.

Clamp Adjustment

If it blows through the frames, but the seal does not require replacement, the reason lies in the loose fit of the wings due to a poorly adjusted pressure mechanism. The solution to this problem is solved by turning the eccentrics. They are located at the end of the window, most often in the amount of three pieces, and have an oval shape. If there is a groove inside them, the adjustment is made using a hexagon, if it is not, then using pliers or pliers. It is necessary to rotate them so that they get closer to the seal. All pins must be rotated so that they are in the same position and the clamp is the same.

The clamping mechanism of the upper part of the sash can be corrected by adjusting the clamping force to the frame. First you need to open the window in the "open" and "airing" at the same time. When the lock works, which does not allow to open two positions at the same time, it is necessary to press its plate on the handle mechanism. If you open the sash, from above you can see the mechanism supporting it. Above or below, a regulator is located on them, which is rotated using a hex key. After this, the sash is pulled to the frame and vice versa (see video).

Repair of plastic windows

Warranty repair and maintenance of a plastic window from the manufacturer is provided, as a rule, for a period of up to two years. After this time, repairs are paid. To save money, windows can be repaired on their own.

Hardware Repair

Over time, window fittings become clogged with dirt and cease to function normally. To restore functions, you need to sort it out. The shutter is removed from the hinges, from which, in turn, the plastic linings are removed. The axis is removed from the upper loop: for this you need to hit on it from above and pull out with pliers from below. Then the sash is pulled out of the lower hinge, the handle and all the screws along the perimeter of the sash, on which the hardware is held, are unscrewed. The mechanism is pulled out of a special groove and treated with a brush with a special flushing fluid, and friction parts are lubricated.

After flushing and lubricating the mechanism, it is installed back, the handle is screwed on, the sash is installed in the hinges.

Maintenance of PVC window fittings, including handles and hinges, should include lubrication and cleaning several times a year.

Installing a new handle and limiter

When replacing the handle or installing the limiter, you can do it yourself by buying them at companies specializing in installing PVC windows or in a hardware store.

To install a new handle, you need to unscrew the old one, which is attached to the screws hidden under the plastic cover. To find them, just turn it 90 degrees.

If it is necessary to install a window opening limiter, the process is similar to the above, but the plate of the ventilation regulator is mounted before installing the handle at its base.

Stick jamming

Sometimes the window handle wedges when the sash is open in the closed position. In this case, you need to look for the problem in the malfunction of the lock. It is designed to protect the window from accidental breakage, and if the handle is quickly moved from one position to another, it may not work correctly. To translate it into the desired mode of operation, you need to know the brand of accessories of the installed double-glazed window.

Move the window sash to a vertical position.
Press the metal plate with the spring, which is located at the end near the handle, to the seal. Then turn the knob.

For accessories ROTO, GU, WINKHAUS, MACO:

Find a plate at the end of the sash, located at an angle with respect to the window.
Move it to a parallel sash position; turn the handle to unlock it.

If the actions taken were unsuccessful, it is recommended to make sure that the blocker engages the response mechanism on the frame. If not, then you need to find the response mechanism on the open window frame, unscrew it, and place the gasket, for example, from plastic.

If you have difficulty turning the handle, you must lubricate its mechanism.

Seal replacement

In order for the seals to serve as long as possible, each season they must be washed, cleaned of dirt and applied with silicone grease.

Rubber seals wear out over time, and in these places the window begins to blow. The sealant can also be replaced on its own. First, its total length is measured, then a new one is bought in any company engaged in the production and installation of plastic windows. It must be borne in mind that there are two of them - internal on the sash and external on the frame. Special glue is also purchased there. Replacement is simple - the old sealant is removed, the glue remains, then a new sealant is inserted from top to bottom in the special grooves, pressed with any suitable tool. In this case, it is not necessary to pull it strongly. Joints of a sealant stick together.

Glass replacement

Broken glass is a nuisance, which can be eliminated only if you order a new one from the supplier. Installing it in profile is not so cheap, but you can do it yourself. If you are not sure about a successful replacement, it is better to turn to professionals for help.

The replacement procedure is as follows:

The glazing beads are removed with the help of light strokes of a metal spatula, which is inserted end-to-end between the frame and the glass packet. Glass is drawn, its dimensions are measured, and this data is transmitted to the manufacturer.
When a new glass is made, straightening plates are inserted during its installation. In the blind casement they are installed at the bottom, in the opening case - in corners with an indent of 10 cm. After the installation of the double-glazed window, it is necessary to check the correctness of its geometry, and, if necessary, mount additional straightening plates. Then the glazing beads are inserted into place, the window is ready (see video).

It should be borne in mind that this instruction does not provide for the replacement of glass in wooden houses, since other technology and tools are required there.

Over time, everyone with plastic windows inserted in the apartment asks a question related to repair work. Five years later, accessories are shaken, including the most expensive. From non-compliance with the rules of care, the sealing element crumbles. It happens that children break a glass bag. Even simple pressure control is carried out twice a year.

A simple thing - repair window handle

During active use, window handles fail. Sagging, the window closes poorly. Instead of eliminating sagging, we begin to strongly press the transom to the frame part, pressing, which makes the handle crack or stop moving.

In case of a similar problem, the cause should be found and eliminated, after which carry out adjustment or complete replacement of the handle. For this purpose, the plate covering the fasteners is turned ninety degrees.

Now - according to the situation. Either the screws are simply pulled in, or another handle is installed.
Next, we will consider a more complex repair of plastic windows with our own hands, a video of the work.

Seal Replacement Procedure

For this window element, it is recommended to arrange care at least twice a year. In the spring and autumn season it should be wiped with a damp cloth, it is allowed to use detergent compositions. From dirt and dust accumulations, the sealing material is lubricated with silicone based grease. If such actions are not performed, then the sealant begins to collapse and transmit thermal energy.

To replace the sealing material, it is purchased in hardware stores. It should be borne in mind that the window has two contours - internal (casement) and external (frame). They should be measured in order to choose the right size. Carefully removing the old gasket, flush the frame. In special grooves, we begin to insert a new seal, moving from above. During operation, you can tighten the gum with any suitable tool. Strong tension should not be created; connecting areas must be glued together

Replacing a bursting double-glazed window

If one glass is cracked, you will have to replace the entire package. This method of repair is considered the most expensive, and if you want to save money - do it yourself.
First of all, we order the manufacture of a double-glazed window, having previously taken the dimensions from the old one.
With a chisel, remove the glazing bead, acting from the corner. Then we pull out the old bag, wash the frame with water and soap in it.

We carry out the installation of a new package, put the glazing beads in their place with a rubber mallet.

We adjust the windows ourselves, video

The installation of plastic windows implies their correct adjustment. To do this job is simple if you have a key on the “four” with six faces. Successively consider the various adjustment positions:

The vertical position of the sash is regulated by a loop located at the bottom. To do this, the window opens, the overlay is removed from the loop. A key is inserted into the upper groove. Turning it in a clockwise direction will raise the frame, and movement in the opposite direction will lower it.

From the bottom loop remove the decorative strip. In the groove located below. We insert the hexagon and rotate it in the direction of the arrow - the leaf moves to the left. In the opposite direction, we will move it to the right.

The upper edge of the window is regulated by the element located at the top of the sash. To do this, the window opens. On the side closest to the hinges, there is a socket with an element for tuning.

The procedure for performing such work can be seen in more detail in the video:

Having completed the replacement of windows and repairing the slopes, many ask the question - how to clean a double-glazed window after repair?
Dust and residual solution can be removed with a rag and soap solution. It is allowed to use detergents.
If the traces of dirt and mortar are decent, then they must first be removed with a sharp blade, or with a clerical knife.
As you can see, there is nothing complicated in repairing windows with your own hands.

Repair of plastic windows is most often more expedient and cheaper than replacing the entire window. Most often, unsatisfactory moments in the operation of windows can be easily fixed by repair.

The main causes of breakdown of PVC plastic windows:

poor assembly at the factory
incorrect installation
violation of operating rules

In this world there is nothing eternal, the same applies to plastic windows. After a certain service life, the design of the window may fail, and plastic windows will need to be repaired.

The most common window defects are:

Jammed pen. Imagine a situation when you opened a window, the handle is turned to the desired position - to the bottom, and it does not work to turn it back to close the window. This may be the result of the handle locking function working, only it turned out to be in the wrong position. The way out of this situation is a special tongue, or plate, which is located near the handle. We press the metal tongue or plate in the direction of the seal and turn the handle as necessary.
It takes a lot of effort to turn the handle. The reason may be that there is not enough lubrication, or the sash is sagging. To begin with, let's try to deal with grease. For these purposes, a special penetrating lubricant, which is available in the form of a spray, is suitable. Elements located at the top must be carefully lubricated. If this procedure did not help, you should go to the screws located on the windows and adjust them. This is done as follows: remove the decorative plugs located on the lower hinges, lift the sash and tighten the screws inside the hinges using the key.
A plastic window crashed or cracked. If you have such a problem, it is recommended to contact the service center, where specialists will take care of the quality of work on replacing the glass unit. You can, of course, turn to the services of a “free” master, but he will simply take apart the double-glazed window, replace the broken glass with a new one and, using sealant, seal it.

But, the problem is that the side plates of the plastic window are equipped with silica gel, which “dries” the air. In the process of improperly dismantling the double-glazed window, the powder - silica gel is saturated with moisture, and after a while a yellow resin may appear on the glass.

How to repair the mechanism of plastic windows?

If nevertheless you are interested in the question of how to repair a double-glazed window yourself, then practical tips follow:

determine the size of the cracked glass, and its thickness. The old broken glass will come in handy in this. To do this, we take out a double-glazed window using a spatula and a chisel;
a putty knife is installed at the junction of the glazing bead and the frame, somewhere in the middle. With a mallet we make light strokes and remove the glazing bead;
we take out the spoiled glass;
a new window, which is not equipped with the “open” function, is installed only on the plates below;
since the window should open, the plates should be installed at a distance of ten centimeters on each side;
adjust the geometry of the wings using plates.

1. "pulls" from the loops. Sashes are exposed to such a problem, on which pivoting and pivoting - folding fittings are installed. This may occur due to improper mounting of the frame or due to straightened plates. How to repair a plastic window if such a nuisance occurs? This will require a wide chisel or a spatula.

We attach the selected tool to the junction of the sash and glazing bead profiles. Lightly tapping, remove the glazing bead. We check the presence of straightening plates and install plates made of plastic in the middle of the frame. As this plate can be the most ordinary line. The width of the new plate should be slightly less than the thickness of the glass.

2. The seal passes air. Here the method of turning the pins, or eccentrics, will help. Such repairs are recommended only in winter period. In the frame mechanism there is a place in which the hexagon is inserted, which will help to turn the same mechanism into the desired position.

If the pins are not positioned correctly, the rollers may not function properly. Then just rearrange the plates. This is done as follows: we move the screw for fastening lower until the roller is in its place.

3. The handle has broken. To replace it, you just need to find two screws near the handle that are responsible for the location of the handle. The screws must be loosened and a broken handle replaced with a new one.
If you are not interested in how to repair plastic windows yourself, then you can resort to the services of service centers.

Then we’ll take a look at the cost of their services. For the replacement or repair of damaged hardware, the master will need to pay from 500 rubles. Replacing a window handle costs about 150 rubles, and the cost of replacing a glass unit starts at 3,500 rubles. Also, specialists can update the appearance of the windows and remove existing scratches. Such a service costs about 100 rubles per 1 cm.
