Understanding the root cause of these problems can save both time and money, helping avoid unnecessary replacements.

Understanding Common Issues With uPVC Windows

Misaligned Hinges or Frames

Misalignment of the hinges or frame can result in uneven closure, which compromises the window’s seal and overall functionality.

Debris or obstructions within the tracks can inhibit the smooth sliding or closing of the window.

How to Diagnose the Problem

A visual inspection of the hinges and frame can reveal alignment issues that are often easy to fix.

Checking for Seal Deterioration

Feel for draughts or look for visible gaps or wear along the seal to identify whether it needs replacing.

Removing Debris From the Track

Check the tracks for dirt or debris and give them a quick clean to see if the window’s movement improves.
