Modern plastic windows have a complex structure, so they can only be repaired if the damage is minor.
For example, the stroke of the handle has become tight, the handle does not immediately respond to pressing – this means that dust, dirt, foreign objects have got into the fittings. Do-it-yourself lubrication and cleaning of fittings.
Do not use acids, resins and oils for cleaning, in order to avoid the destruction of anti-corrosion protection. Also, the integrity of the coating can be violated by detergents containing abrasives.
Repair of a plastic window handle is necessary if it is jammed or loose. In this case, tighten the bolts. Slide the outer trim to the side to gain access to the fasteners. Arm yourself with a screwdriver and tighten the bolts, but do not tighten them too tight. Inspect the adjusting screws, they may need to be lubricated.
It happens that the handle is jammed in the “open” position of the sash. The cause of the malfunction is the jamming of the blocker. Gently turn the tongue until it is parallel to the frame, turn the handle.
If the fittings are cracked or you decide to install a lock handle, buy a new one and install it yourself.
If the handle does not turn all the way, the grease may have dried up or the sash may have sagged. Inspect the frame for sagging, if everything is fine, buy an all-purpose lubricant and lubricate the fittings. These methods did not help? Then you should call the master.
In case of thermal expansion, it happens that the blocker does not come into contact with the response mechanism. Open the window, find the counter element located on the frame. Unscrew the screws that secure it and place the plastic lining. The action will achieve the adhesion of the blocker and the response element.
If you are not sure that you will cope with the tasks, do not take risks and call the master.
