Common uPVC Door and Window Problems We Fix
uPVC mechanisms can become worn or misaligned over time, especially after years of daily use.
Below are some of the most frequent problems we repair across Welwyn Garden City homes:
uPVC Door Handle Repairs and Replacements
Stiff, loose or drooping uPVC door handles can be caused by worn internal parts, a failing gearbox or pressure from a misaligned door. We identify the cause and adjust, repair or replace the handle and related components as needed.
Keys Turning but Doors Not Unlocking
Often caused by a failed multipoint gearbox or broken internal spring. We replace faulty units using genuine manufacturer components.
Misaligned Doors Causing Locking Issues
When doors drop or warp, they put stress on the locking mechanism. We perform precise heel-and-toe adjustments to realign doors correctly.
Broken or Jammed Multipoint Gearboxes
If your door will not open or lock fully, we can remove and replace the gearbox safely without damaging the door or frame.
uPVC Window Hinge and Lock Repairs
Faulty hinges or locking mechanisms can prevent a uPVC window from closing tightly, causing draughts or water ingress. We replace worn friction stays, repair window locking mechanisms and adjust the window so it closes securely.

How We Repair uPVC Doors and Windows
We identify the cause of the fault before recommending any repair or replacement.
- Inspection and Diagnosis
We assess the fault, check the door or window alignment, and test the handles, hinges, cylinders and locking mechanisms to identify the exact cause.
- Professional Repair or Replacement
Where practical, we repair the existing components or replace only the failed parts. We carry a wide range of uPVC door and window locks, gearboxes, hinges and handles, allowing many repairs to be completed on the first visit.
- Adjustment and Realignment
If a door or window has dropped, we carefully adjust it so the locking points engage correctly without forcing the handle or locking mechanism.
- Full Function and Security Testing
Before finishing, we test the door or window through its full operation to ensure it opens, closes and locks securely without placing unnecessary pressure on the mechanism.
The aim is to restore reliable operation, repairing existing components where practical and replacing only what is necessary.
Replacement Parts and Security Upgrades
Many uPVC door and window faults can be repaired by replacing only the failed component, avoiding the unnecessary cost of replacing the entire door or window.
For door security upgrades, Active Lock Centre can supply and fit high-security euro cylinders, including Ultion 3 Star PLUS (ALPS) cylinders. These cylinders are TS007 3-star rated and Sold Secure Diamond approved, providing protection against common attacks including snapping, picking, bumping and drilling.
We also supply and fit, where suitable:
• Replacement uPVC door handles in a range of sizes and finishes.
• Multipoint lock gearboxes and complete locking mechanisms.
• uPVC window hinges, handles and espagnolette locking mechanisms.
• Keeps and strike plates to help the locking points engage correctly.
• Replacement letter plates and other compatible door fittings, subject to availability.
