Common UPVC Window Problems We Fix
UPVC windows are durable, but after 10–20 years components start to wear. The good news is that most problems can be repaired without replacing the entire window. At Restoration Glazing, we always recommend the most cost-effective option — repair where possible, replacement when it makes more sense.
What We Can Repair
- Broken or stiff handles
- Failed window locks and espagnolettes

Yes — the vast majority of UPVC window repairs involve replacing individual components (handles, hinges, locks, seals, or glass units) while retaining the existing frame. This is far more cost-effective than full replacement.
If your frames are warped, cracked, severely discoloured, or over 20 years old, replacement is usually the better investment. Modern A-rated windows offer significantly better thermal performance and security.
