Do-it-yourself plastic window repair window does not close

In detail: do-it-yourself plastic window repair the window does not close from a real wizard for the site my.housecope.com.

Sharp repetitions of the handle, lack of knowledge about proper operation and maintenance lead to a common problem - the plastic window does not close. If plastic windows are under warranty, we advise you to call a specialist to help you solve the problem. However, if the warranty period has expired and you do not want to spend extra money on calling a specialist, we suggest that you familiarize yourself with a detailed plan of action on how to repair a broken plastic window yourself.

At least once during the entire period of operation, the following problem arises - you cannot close or, on the contrary, open the window, the handle is jammed. The reasons may be as follows:

lack of lubrication of parts, accumulation of dust and dirt;
breakage of the sash mechanism, which is responsible for its movement;
improper installation of PVC windows, mechanical damage;
shrinking the house, changing the geometry of the window.

If in the first case you can easily fix the problem yourself, then you cannot do without the help of a competent specialist to solve other problems. However, as a rule, everything is much simpler - the blocker is mistakenly triggered. Why is this happening? The main purpose of this mechanism is to transfer the window frame to a folding or pivoting position. Sudden movements cause the system to block, the handle gets jammed, and the window frame takes an intermediate position between the tilt and open state. Especially often this problem arises when, in the sash opening mode, the handle is switched to the tilt (ventilation) mode, that is, it goes from the vertical position to the horizontal one. The first thing to do in this situation is to find out the brand of fittings, which is indicated on the metal constipation.

Repair of AUBI brand plastic window fittings is carried out as follows. In the area of the handle we find a thin metal plate with a spring, press it against the seal and carefully turn the handle, setting the window sash in a vertical position.

The principle of operation in plastic windows with fittings from Maco, Roto, Winkhaus, GU, Rehau and other firms is similar. Instead of a spring, we find a metal “tongue” on the side of the strike plate, clamp it strictly in a vertical position and in parallel press the upper flap corner to the sash, smoothly bring the handle to a horizontal position. After these manipulations, the window should close well. If a lock is not installed in the fittings, press the upper corner of the sash and turn the handle.

There is also a situation when the window is closed and the handle does not turn in either direction, the locking mechanism is completely blocked, and a backlash is heard. How do we repair the window in this case? With one hand we hold on to the handle, and with the other we gently push it into the gap that has formed around the upper hinge, slightly push the edge of the sash and smoothly turn the handle, we do both manipulations at the same time. After the window opens, we eliminate the cause of the problem. As a rule, the system is blocked due to the incorrect position of the clamping eccentric. If it is at an angle, take the pliers and turn the eccentric vertically. This will make it easier for him to enter the striker plate, not to push the frame away, the closing window will not jam.

If correcting the problem with the interlock does not help, the knob mechanism is most likely broken. Replacing the old part will help. How to remove and install a new plastic window handle with your own hands? There is nothing difficult here.We turn the decorative plate at the base of the handle by 90 °, using a screwdriver or screwdriver, unscrew the two bolts and remove the old handle. We install the new mechanism on the mounts and tighten it with the previously removed bolts. Want to install an opening limiter? Then, before installation, we attach a special plate (comb) at the base of the handle, with which you can install plastic windows for micro and macro ventilation. Next, we act according to the familiar scheme - we put the handle, screw in the bolts and return the decorative plate to its original position.

Advice, if there are children in the house, install safety handles that are locked with a key. This mechanism guarantees safety and excludes the possibility of accidental opening (closing).

The handle turns freely 360 °, the window won't open? This indicates that the problem lies not with the handle itself, but with the inner lock. It is more likely that the gear that drives the swing-out plates and the trunnion is broken. It is difficult to repair the part on your own; in this case, you need to call a specialist and change the internal lock. For comparison, replacing a regular handle made of white plastic from a specialist will cost you about 300 rubles, and a swing-out mechanism – at 4500 rubles. Therefore, as soon as you hear a backlash in the handle, a crackle, an uncharacteristic click or the mechanism has become jammed, it is worthwhile to diagnose and find out the reason.

Timely lubrication of the moving parts of the window system - 50% of the success of long-term operation. The lubricant provides smooth rotation of the main parts of the locking mechanism, while maintaining their mobility and wear resistance. The composition applied at the factory is enough for 4–5 years, after which the lubricants dry out and need prevention.

Regular lubrication of mechanisms

The frequency of this event depends on the operating conditions of the window. If it is located far from sources of increased vibration, noise, prevention once a year will be enough, it is advisable to carry it out in the spring with the onset of heat. If the windows are used in more severe conditions with a sharp temperature drop, near noisy highways and construction sites, we recommend lubricating the parts 2–3 times a year. Do-it-yourself mini-repair of plastic windows is carried out as follows.

First, a lubricant is selected. You can use both improvised and specialized materials. Any engine oil without resin and acids, silicone grease and aerosol cleaner for plastic windows WD-40 will do. But the use of vegetable or butter, as well as cosmetic gels and petroleum jelly is not recommended. Such materials can further aggravate the performance of moving parts.

Lubricants are applied only to the cleaned surface. Therefore, before carrying out the procedure, we thoroughly wipe the glass and metal locking parts from dust and dirt, remove everything with a damp cloth. To remove old grease in hard-to-reach places, use an unnecessary toothbrush. Further, we grease the moving parts abundantly: brackets, “scissors”, latches, bolts, fasteners, we pay special attention to the handle mechanism. For ease of application, we recommend using an aerosol spray that can penetrate into the most inaccessible places. Using lubricants in bottles, add 2-3 drops of the composition to each gap. To distribute the composition evenly throughout the locking mechanism, turn the handle several times. Do not ignore the rubber seals, which also dry out and need to be moistened.

Application of lubricants

What to do if the plastic window continues to fit tightly into the striker and does not close? Most likely, the sash does not close well due to the sagging of the window profile.In this case, it is necessary to check this theory and, if it is confirmed, tighten the corresponding screws. How to do this, we will tell you in more detail below.

The shrinkage of the house and the wear and tear of parts of the window structure fail over time, the sashes do not close tightly and touch the plastic profile. As a result, there is a skewing of the window and disruption of the operation of moving mechanisms. How do I check for a problem? Close the window and mark with a pencil the places where the position of the sash on the frame ends. After opening, measure the distance from the received mark to the frame; it should be no more than 5–7 mm. Otherwise, adjustment is carried out in those places where it is necessary. Tight-closing windows can be adjusted with your own hands or call a master.

You will need a 4mm hex wrench and pliers for this job. Let's start by adjusting the sash in a vertical position. We remove the decorative cover from the lower hinge, insert the hex key into the upper groove and turn it in the direction we need. When the key is turned clockwise - the sash rises, and counterclockwise - lowers.

Adjustment of the sash position in the horizontal position (left-right) is also carried out using a hex key. We insert it into the groove from the inside of the lower hinge, that is, with the window open. Turning the key clockwise pulls the sash to the left, and counterclockwise to the right. Adjustment in the horizontal plane is also carried out in the upper part of the open sash. Here you will also see a hex groove, insert the key into it and do the same steps as in the lower part.

If, after all these manipulations, the plastic window does not close tightly, air is passed through, it is necessary to additionally adjust the trunnions (round or oval elements) by pressing them more strongly against the seal. The position of the pins (eccentrics) is key and keyless. In the first version, they are adjusted using a hex wrench, and in the second, pliers are used, all the elements that are located along the perimeter of the frame are pressed.

For preventive purposes, we carry out such adjustment of the fittings once a year. At the same time, do not forget to change the position of the eccentric for summer and winter time. To determine which mode you have, we clamp a sheet of paper in the window sash. If it stretches easily, this is a summer mode, it stretches tight and tears - a winter one.

Preventive adjustments should be made once a year.

The standard position of the eccentric is off-season, the elements are installed at an angle. To make the clamp weaker, set the trunnions strictly vertically in the summer, and stronger horizontally in the winter. Do not leave the eccentric in a horizontal position throughout the year. This puts a lot of stress on the seal and will soon have to be replaced. And if such a need arose, the plastic window does not close tightly and the rubber sagged, then the answer to the question of what to do is obvious - you need to change the seal. We advise you to give preference to products of German manufacturers, which will last at least 10-15 years. We remove the old seal, carefully clean the groove from dust and dirt, grease it with glue around the entire perimeter of the frame and carefully lay the seal, avoiding pinching and stretching the material.

There is a crack in the glass, invite a specialist. If the window is under warranty and it is proved that the mechanical damage was not your fault, then the glass unit will be replaced free of charge. However, if the warranty period has passed, and you do not have the money to call a specialist, you can take temporary measures and carry out a surface repair of metal-plastic windows with your own hands. A transparent sealant is suitable for this, we recommend using Sintesel Multiuso, Bau Master Aquarium, in extreme cases, use optical glue from Bohle or OK-50P. Apply the sealant twice with a break of 2-4 hours.We remind you once again that such a cosmetic repair of plastic windows with your own hands will not save you from solving the problem, but will only postpone it for a while.

To prevent further cracking, call an experienced foreman to replace the glass unit, and if you have good skills as a glazier and measurer, then our recommendations will be useful to you.We start by removing the broken glass. You will need a spatula and a rubber mallet to pull it out of the frame. We pass the spatula into the joint between the window frame and the glazing bead, we begin to tap on it with a mallet. First we move aside the vertical glazing beads, then the lower and upper ones, take out the glass. We work in tight gloves so as not to injure our hands, preferably with an assistant. We clean the old sealant from the inner surface of the frame, and remove the sticky residues with a solvent - acetone or white spirit. We cut out the glass according to measurements, observing the accuracy, an error of 1 mm is allowed. Before installation, wipe the glass surface with a dry cloth. We put sealant on the distance aluminum frame, insert the glass into the groove, here you will also need an assistant to make the connections as accurate as possible. We cover the glass unit from the ends with butyl tape. This completes the repair of double-glazed windows with your own hands. It remains to wait until the sealant is completely dry (the time is indicated by the manufacturer) and you can insert the glass unit into the window frame.Window repairs may suddenly become necessary, no matter what type of construction you have installed. Many problems can be corrected without the help of a wizard, by doing it yourself. It is enough to know how to eliminate the most common problems with plastic windows.Even if you have supplied high-quality products and made them correctly, over time, the handle may fail or it will be necessary to replace the insulation. It is possible that the glass breaks or the mechanism requires adjustment. This repair of plastic windows is within the power of the owners.This problem is common and easy to fix. First you need to buy a new window handle. You can do this at a home improvement store. To replace it, you will need to find the decorative plate, which is located directly under the handle, then turn it so that you can see the screws that will need to be removed.After that, the old handle can be removed without any problems, and a new one can be put in its place. Re-tighten the screws; at the same time, you can install a limiter for opening. To do this, it is necessary to mount a regulator plate for ventilation into the base of the element, after which the handle can be screwed on.Repair of window fittings is not so difficult even if it has jammed. To do this, you need to find and disable the blocker. The scheme of actions depends on which fittings you have installed. If it is AUBI brand, you will need to find a metal plate with a spring: usually it is near the handle. Press it against the seal and try to smoothly turn the handle. Other brands of hardware, such as Maco, GU, Winkhaus or Roto, have a metal tongue on the bottom. It needs to be pressed, forcing it to stand parallel to the sash.Sometimes this method does not help, and then it is worth checking if the blocker is hooked. To fix the problem, you need to open the window and find the place where this element touches. After that, you must remove the bollard mounts, install a plastic gasket between it and the clinging structural element, and put the part back.Do not be afraid to repair plastic windows with your own hands. The window does not close – It's not a problem. This usually happens for the reason that the handle does not turn due to the lack of lubricant in the fittings or the sagging of the sash itself. The latter can be determined visually by carefully examining the window.The product can be adjusted by tightening the bolts that hold it. If everything is in order, it is worth checking the lubrication. You will need to purchase a special tool, and it is desirable to lubricate all parts of the mechanism that are set in motion.Timely maintenance of plastic windows will help to avoid many problems. However, if the product does not sag and lubrication does not work, you will most likely need professional help.

The screws are under the plastic panel

If the handle just dangles, tighten the bolts; if the handle is broken and cannot be restored, we simply replace it with a new one and use it. You can buy such a handle at every construction market or from dealers and sellers of plastic windows. In a word, one of the few problems that can be solved without the help of a specialist.

Another problem: the handle may just stick. If it feels “tight”, roll it up, remove dust and debris, and spray with WD-40 spray.

Before you start fixing something, you need to know if it needs fixing. We close the window and use a lighter to reveal the presence of "see-through" areas. If the flame flutters, let's get down to business. If you look at the window sash from the end, you can see three oval (most often) eccentrics. Try to twist the window handle - and you will see that the eccentrics "work". So, they need to be twisted, but quite a bit, often a couple of millimeters is enough. Plus, there will be a reserve for a few more twists: do not forget that the seal also wears out. And, most importantly, do it so that the eccentrics are strictly in one position. To work with them, you will need either pliers or a hexagon. It is very useful that the eccentrics themselves have certain marks: if you see that they are "looking" at the street, you need to press harder, but if the lines are directed into the house, the clamp is very good.

Setting the pressure mechanism

Now let's look at different types of adjustments that have their own significant differences. In order to move the frame to some extent or get rid of the bevel, it is precisely the horizontal adjustment that is necessary.

It is carried out as follows: a hexagon is alternately inserted into the upper and lower loop (there are special holes there). When you start turning the hexagon clockwise, the window will rise noticeably.When you rotate in the opposite direction, that is, counterclockwise, you will see that the window, on the contrary, is lowered. This procedure must be done strictly with an open window and move the sash no more than 2 mm, so as not to "drag" the mechanism and not damage it.

Windows made of metal-plastic can be adjusted using the lower hinge. In this case, vertical adjustment is used. It is necessary to remove the plug and open access for the hexagon, then turn it clockwise. As you can see, there are no difficulties here either.

I would like to briefly describe the principle of ventilation at plastic windows. 90% of such windows do not provide for the good old vents, but they have a ventilation mode that everyone loves. For three seasons, this mode pleases, and on the fourth - frosty - a person finds himself in a difficult situation: either freezing or not airing at all. If you are not a lucky owner of a plastic window with self-ventilation, you can use a comb, which will one hundred percent perform the function of a ventilation regulator (and it costs a penny). Such a simple device is suitable for almost every plastic window and has 4 modes (or rather, 4 "arches" for adjusting the air flow into the room).

One of the less common, but occurring problems - the need to replace the glass unit. Here you need to clearly understand what you have to do, and, accordingly, be aware of what mistakes will lead to. If you are not sure, contact the experts on the issue.

Changing a glass unit requires skills

So, we take an ordinary metal spatula and a rubber mallet. We remove all the glazing beads (insert a spatula into the gap between the glass unit and the frame, lightly hit it, repeat the procedure). Having freed the glass in such a way, we take it out. You only need to do this together, because it is much heavier than it seems. Next, we measure the dimensions of the glass, order it, meet it with a courier. The next step is to install the straightening plates (it is important to remember that if the sash of the window is hinged, we indent at the corners of 10 cm.) We fix the new glass in its rightful place, see that it is in a geometrically correct (even) position and fix it with glazing beads. If you strictly follow all the instructions, everything should go without a hitch.

And the last - not uncommon - phenomenon: the sash opens simultaneously in two directions: immediately in the swing and in the tilt mode. Almost everyone has encountered this. It is necessary to make sure that the upper flap is firmly pressed. To do this, we put it vertically (naturally, leaving it open). The handle at this moment should be in the "open" position, that is, in a horizontal position.

The sash opens simultaneously in two directions

Close the window and carefully turn the handle down. Gently and slowly "try" the handle: turn it up and down. If everything is in order, it means that everything worked in the same mode and the problem is solved.

So, PVC windows are a level of comfort that is already familiar to many, but manufacturers of plastic windows often do not tell users about the possibilities of self-repair and adjustment. The reason for this is quite understandable: in 2-3 years, or even less, the user will come to choose and install a new PVC window. But in essence, do-it-yourself pvc window repair is an intuitive and quite simple mission, the main thing is not to overdo it, not to overdo it and make sure that the repair is carried out exactly where it is needed, that is, go away from the problem.

In case you are not confident in your abilities, just contact the company where the windows were installed, perhaps the specialists will help you at a reasonable price and with knowledge of the matter, and maybe even under a guarantee (if its term has not expired).

A situation often arises that the installed plastic window stops closing. What to do in this case? It turns out that there is no need to call the master and pay for his services.It is quite possible to make all the adjustments with your own hands. Today we will try to figure out what to do if the plastic window does not close, as well as analyze other possible problems and methods for their elimination. It also makes sense to know how to carry out maintenance, prevention and adjustment of locking mechanisms.

Plastic windows have long and firmly entered our life

The sash can be adjusted according to various parameters.

There can be a lot of small problems. And most often they are all quite simply solved by conventional adjustment. Less often, windows require replacement of seals. The main faults are:

Sash skew and loose fit to the frame;
Jammed handle in various positions;
Sash opening simultaneously for airing and opening;
Looseness of the handle;
Blocking the drain bar.

And this is switching to winter mode

We will deal with the listed malfunctions and methods of adjusting and repairing plastic windows.

A common reason for improper installation and initial adjustment. You will need a hexagon (usually # 4) to fix it. Here you need to understand that the upper sash hinge is responsible for adjusting the window to the left and right, relative to the frame, and the lower one - up and down. If the sash is skewed, then it must be urgently corrected. Otherwise, damage to the glass unit itself is possible, which is not cheap.

It is also possible to adjust by placing special spacers between the frame and the glass unit - for this you will have to remove the glazing beads. Work is carried out with the sash open, with periodic checks - the sash closes smoothly, while it is immediately clear whether the repair has been completed or not.

It's easy to find an adjusting key on sale

This can happen if plastic windows are not switched to winter mode after a warm period. This is not difficult to do. Having opened the window, you should carefully consider the locking mechanism - there should be a corresponding mark on it. Usually, to transfer the mode, it is necessary to turn the central latch using a hexagon. After that, you need to close the window by pressing a sheet of paper with it. If done correctly, the paper cannot be pulled out.

In the occurrence of such a problem, the blocker is most often to blame. This is a device that locks the locking mechanism in certain positions. With prolonged use of windows, it may work in the wrong position. Most often this happens when you turn the knob to the "closed" state while the window is open. To eliminate it, it is necessary to bring the sash to a vertical position, after which the handle should turn. If this does not happen, most likely, you will have to change the locking mechanism.

Triple glazed windows are installed in colder regions

It can also happen that the handle wedges when it is not fully turned. The cause of such a nuisance can be both clogging of the mechanism and drying out of the lubricant. In the second case, everything is solved quite simply - in stores now there is a large assortment of various sprays. The best option is to use a silicone grease. If the mechanism is clogged, then it must be disassembled and cleaned.

Important! When disassembling the locking mechanism, you need to remember the sequence of installing the parts. If there is little hope for memory and attentiveness, it is better to seek help from specialists.

The ventilation mode is quite convenient not only in summer, but also in winter.

If the mechanism is jammed and the plastic window does not open (what to do), the video instruction will help you figure it out.

The reason for this may not be a malfunction, but a banal inaccuracy when opening. The problem is easily eliminated. The handle pivots upward, while the sash must be firmly pressed against the frame by hand. When it is in place, we lower the handle down until it stops. Such actions should not be difficult.

High-quality double-glazed windows - the guarantee of silence and comfort in the home

All modern plastic windows are equipped with blockers that prevent such situations, however, excessive haste when opening it may prevent it from working. Do not try to open the sash when the handle is not in the right position - this will save you a lot of problems.

This problem can be easily solved on your own. To do this, turn the handle base plate clockwise. There will be two screws under it, which need to be tightened. If they are torn off, you will have to replace the handle completely, choosing a suitable one in the store.

In general, customizing plastic windows with your own hands is not difficult. It is only necessary to fully understand the design of the locking mechanism. The very same arrangement of plastic windows for different models differs slightly.

Much depends on the skill of the installers

In this case, you will have to disassemble the locking mechanism. This could be due to debris and foreign objects getting between parts. Defective parts are replaced with new ones if necessary. It is better to entrust such work to specialists. Otherwise, there is a great risk that the mechanism will have to be blamed completely.

Such a malfunction does not require any special knowledge and skills to fix it. What if the plastic window does not close for this reason? The answer is very simple: you need to open the sash and just fix the ebb so that it does not interfere.

Competent specialists do the job very carefully

To extend the service life of a plastic window, periodic maintenance should be carried out. It is imperative to lubricate all parts of the locking mechanisms. Likewise, the adjustment of the sash plays a rather important role: it allows you to increase the durability of the elastic bands, which ensure tight closing, and reduces the risk of the need and repair of plastic window fittings.

Before the production of periodic preventive maintenance, the technical documentation of plastic products and their locking mechanisms should be studied as carefully as possible, so as not to aggravate malfunctions instead of preventing them.

Such glazing beads hold the glass unit in the frame

Most often, parts of window fittings that have become unusable cannot be repaired and require replacement. In this case, it is very important to pay attention to the weight of the window sash itself - this will be of decisive importance when purchasing hinges or a locking mechanism. The fittings may fit perfectly in size, but if it is designed for less weight, there will be no sense in such a replacement.

The design of the window is also important - it depends on which details will fit it and which will not.

Important information! If the replacement of the swing-out mechanism for a plastic window is not urgent and you can get by with the adjustment, do not rush to purchase. The later the repair is made, the longer the spare parts will last. It should be understood that native parts very often turn out to be of much higher quality than purchased separately.

Custom-made double-glazed windows are more expensive, but at the same time they are made exclusively according to the size of the customer

It is most convenient to lubricate the locking and swing-out mechanisms of plastic windows with special lubricating sprays, the assortment of which is quite wide on store shelves. Such sprays perfectly penetrate between moving, rubbing parts. It is recommended to carry out these works at least two to three times a year.

But at least once a year, it is necessary not only to smear, but also to clean the mechanisms of the old substance. It is on it that all the dirt and dust is collected, which eventually makes the part unusable. But before performing such work, it is necessary to study in detail the device, which is quite complex and, if incorrectly followed by installation, will simply stop working.

All mechanisms should be lubricated periodically.

When using plastic windows, do not underestimate the importance of preventive maintenance.After all, if their age is not small, there is no guarantee that if any part fails, it will be possible to find a similar one. Otherwise, it is necessary to change the entire mechanism and it is not a fact that it will succeed. Or, the entire window goes under the replacement, which can make a decent hole in the family budget. That is why it is worth listening carefully to the sounds that accompany the opening and closing of the sash. When a metal grinding occurs, it is necessary to urgently lubricate and clean the parts.

By moving the plug, you can stretch the fastening screws if the handle is loose

Adjustment is also required periodically. Do not forget about switching seasonal modes - this will significantly extend the service life of plastic windows.

High-quality ventilation is also very important - it does not allow condensation to accumulate on the windows. In winter, it can turn into ice on the profile, which has a detrimental effect on it. The same advice can be attributed to the fact that heating radiators should be located under the window to remove excess moisture.

Plastic windows can be large enough

Not all malfunctions can be dealt with on your own. Very often, the plastic window does not open due to a jammed handle and the problem cannot be solved with your own hands. In this case, the help of a specialist is needed. But if the windows in the apartment were installed recently, then a company respecting itself and the client had to give a guarantee. Then you shouldn't look for a specialist on the side.

Well, if the warranty service has already ended, you can look for masters on the Internet. But it is worth remembering that you need to study customer reviews about a particular company as carefully as possible. After all, I do not want to pay a lot of money for outright hack. Indeed, in this case, it may turn out the same way as one of the Internet users.

WD-40 is a pretty good lubricant, but silicone is still better

Surely everyone understood that it is better to carry out periodic maintenance on their own, than to face serious problems that require the help of a specialist. After all, if you follow all the instructions specified in the technical documentation, adjustment and lubrication will not cause any special difficulties. But the fact that these actions significantly extend the life of the windows is an indisputable fact.
