Why uPVC Windows Fail and How to Fix the Problem

uPVC windows are quite popular in the Georgian climate, but over time, their mechanisms wear out and often require adjustment. If your window is jamming, the seal has been compromised, or the handle is hard to turn, the problem is not always critical and can often be resolved at home.

Diagnosing the Problem

Before calling a technician—whose visit often costs between 30 and 80 GEL—check the main causes:

  1. Window Sagging: If the window hits the bottom of the frame, the problem lies in adjusting the hinges.
  2. Seal Failure: When switching from summer to winter mode (or vice versa), the window pins require turning the regulator.
  3. Stuck Handle: The mechanism needs cleaning and lubrication with special oil.

Step-by-Step Adjustment Guide

To start the work, you will need a hex key, also known as an Allen wrench, size 4 mm.

1. Horizontal and Vertical Window Adjustment

Small screws are located on the hinges to control the window's position. Using the top and bottom hinges, you can slightly lift or shift the window so it closes freely.

2. Changing Seasonal Modes

Rounded or oval pins are located on the edges of the window sash. By rotating them, you change the pressure applied to the window frame. Switching to winter mode ensures better insulation, while summer mode reduces the stress and wear on the rubber gasket.

3. Lubricating the Mechanism

Moving metal parts should be cleaned of dust every six months and lubricated with a special aerosol lubricant or sewing machine oil. Avoid using sunflower oil, as it collects dust and accelerates the deterioration of the mechanism.

When is Specialist Help Necessary?

If you see that the mechanism is broken or the window glass is damaged, independent intervention may worsen the situation.
