Modern windows are easy to use, butsometimes unexpected problems arise. This means that repairing metal-plastic windows with your own hands is an integral part of their use. Of course, you can call a specialist to your home who can fix all the problems, but this will be expensive. Knowing the basic principles of operation of all components of this design, you can independently carry out repairs and adjustments.
Metal-plastic windows are easy to maintain and convenient to use - you can repair and adjust the windows yourself.
Repair of plastic windows
Signs of problems can be completely different.For example, the handle on the window may become loose, the window does not move into the correct position, condensation and drafts appear, etc. In order to correctly determine the cause, it is necessary to pay attention to some nuances:
-
The device of a metal-plastic window. The handle is out of order; - the window jammed;
- draft from the loop area;
- inflation from the sealant;
- the glass cracked.
These and other breakdowns deserve special attention.Attention. To replace the handle, you must first buy it. Try to choose the same one as before. If any other mechanism is broken, you need to do the same. But before you go to the store, determine the type of malfunction, because sometimes it is enough to simply adjust the mechanism. The only tool you will need is a screwdriver. Return to the table of contents</a>If there is a draft Repair of metal-plasticwindows is also carried out if a draft is felt. This primarily indicates that some element of the mechanism is broken or loose. Initially, you need to determine the area from which the wind is blowing. In the cold season, this is much easier to do, since it is enough to run your hand along all the lines of the sash and frame connection and in the area where the frame is joined to the window sill. In the warm period, you need to bring a lit match or lighter to the same places. The second is preferable, since the burning time is longer. Accordingly, in the area where the flame tongue deviates, there is a problem.
Sealing scheme for a metal-plastic window.If there is a draft between the window sill and the frame, you just need to seal these areas. The initial installation of metal-plastic windows involves applying a sealant, but not all craftsmen are responsible for their work, so check all these areas yourself and, if necessary, seal again. Only do this after all the old burrs have been cut off, that is, excess hardened foam. Sometimes a draft occurs in the area of the window sash, which indicates that the sash does not fit tightly to the frame or it is warped. Basically, the warp occurs where the handle is located, but in the upper corner. Perhaps the reason lies in subsidence. To install, you need to raise the corner part of the sash or completely replace the glass unit. That is, it must be removed from the frame, while lifting (slightly) the problem area and fixing it. After this, the glass unit is re-installed. If the blowing occurs because the frame is not pressed tightly, then it is necessary to correct the clamping device, that is, the trunnion or locking plate is pressed. It also happens that during installation, the craftsmen forget about installing some parts of the fittings, so there is a draft in these places. Check and install the missing elements. Most manufacturers include special clamping devices in the kit, the installation of which is carried out from the side of the hinge attachment at the top and bottom.

To replace a broken window handle,it is enough to use a regular screwdriver. If the handle of the metal-plastic windows is broken, it must be replaced, but it is not necessary to remove the entire mechanism for this. In order to remove the broken element, you need to turn the plate (plastic) by 90 ° and unscrew the bolts located under it with a screwdriver. Everything broken is removed, and a new handle is installed in its place in the same order in which it was disassembled. That is, the handle must be placed against the mechanism and tightened with the same bolts, and then return the plate to its original position. If the window, being open, cannot be closed later, then the handle is jammed. And in this case, you can fix the problem yourself. The fact is that modern models of metal-plastic windows are equipped with certain blockers that are triggered if the handle is pulled with a sharp movement. In the area of the handle there is a metal plate with a spring. It is this that must be pressed against the seal and simply turn the handle itself. In this case, the window sash must be located only in a vertical position. If the above does not bring success, then the blocker requires repair. If you try to forcibly close the sash, there is a risk of breaking the locking gear. To repair the blocker, you must first remove the window sash and decorative trim, then remove the pin. The removed window is installed on the floor in a vertical position, the screws and scissors are unscrewed. Then the blocking device is completely removed, and the scissors are installed in place. If you still want the blocker to be there, then you need to buy it and install it. The handle may lose its ability to turn. This indicates that the sash has sagged or the lubricant has simply run out. After lubricating all moving parts, the handle should work again. If this does not happen, then simply tighten the screws on the hinges. If this device for opening the window has simply loosened, then tighten the bolts. If it becomes problematic to pull the handle to the full closing state, then you overdid it when tightening the fasteners: just loosen them a little. Sometimes all mechanisms of this kind need to be cleaned, because a lot of dust accumulates there, which over time interferes with the normal functioning of the device. To do this, it is necessary to dismantle all the mechanisms one by one and clean them with a brush, or better yet, blow out the entire system with a vacuum cleaner. Then everything is lubricated and the parts are installed. Return to contents</a>Problems with the clamping mechanism CauseThe blowing may be caused by a sealing rubber, which weakens and loses its volume over time. If so, replace the seal. Windows are quite sensitive to thermal changes, which may be the cause of the malfunction. In fact, the hardware design provides for appropriate regulation, but few people know about it. A fairly common problem is the failure of the clamping device, which includes seasonal adjustment so that the structure does not suffer from temperature changes. As a rule, the position of the clamping mechanism should be changed twice a year, that is, in the fall and spring. This does not require repair, but only adjustment. On the end part of the window sash, there are cylinders that protrude. They have an oval shape and are located in the holes of the plugs. In other words, these are trunnions or eccentrics. On the frame there are mating hooking parts into which the trunnions enter when the handle is turned. Thanks to this, the sash closes tightly. To change the position of the pressure, you need to turn the trunnions or the counter-hooks - whichever is more convenient.
Adjustment of metal-plastic clamping pinswindows. This is done as follows: the most protruding part of the trunnion is turned to the inside of the surface of the entire structure, so the pressure becomes stronger. To weaken it, these turns must be made to the outside. Accordingly, weakening is done in the spring, and pressing - in the fall. After this, it is necessary to adjust the awnings. In this case, it is better to consider the option of a transom-type window, since it is the most popular and complex. The transom system allows the sash not only to open, but also to be held in a ventilation state. To do this, the cap of the casing is removed from the bottom, but do it carefully so that it does not burst. Next, you will see a hex bolt. Of course, there is another one there, more hidden, but you will not need it. With the help of a hexagon, you can quite easily adjust the state of the clamp. Upon completion of the work, you need to install all the components. In the upper part of the window sash there is a device called scissors. To make repairs in this area, you need to set the window to the open mode. This is the only way to access the adjusting bolts in the scissors. There is a clip (lever) on the end near the handle, which you need to press. Remaining in this position, the handle turns to the ventilation mode. The open window will take a position convenient for you, holding its weight on the scissors and the canopy. This is how you get to the head, which helps to make the adjustment. After this, all the parts and positions are reinstalled. Return to the table of contents</a>Other faults and their repair SometimesIt happens that the sash starts to slightly touch the window frame. If this happens on the side where the handle is, then the sash is lifted and its upper part is turned towards the top mount. If it touches in the middle area along the end, then the sash shifts towards the hinges. If the point of contact shifts to the upper or lower side, you need to turn the sash towards where the shift occurs. If it touches the upper end, turn it towards the lower hinge and vice versa. To completely replace the seal, you first need to pull out the old one and be sure to thoroughly wash and wipe all the grooves. After that, you need to lubricate them with special glue and install the seal. You need to start it slowly and very carefully, because the quality of the clamp will depend on this. The sealing cord should never be compressed or stretched. After its installation, it is kept for some time (depending on the glue), and only then you can close the window and consider the repair complete. If the problem is a broken glass unit, do not despair. But if you think that you cannot cope with this kind of problem, then call a specialist. Although it is worth trying to do this repair yourself. You have nothing to lose and at any stage you can ask for help from specialists. Now you know how to eliminate faults in metal-plastic windows with your own hands, at least the most common ones. Recommendations from experienced specialists will always help you in implementing your plans.
