uPVC and double-glazed door and window repairs
Repairs for failed locks, multipoint mechanisms, handles, hinges and alignment problems across the areas GP Locksmiths covers.
Repair the fault, not just the visible symptom
Door and window problems often involve several connected components. A stiff handle may be caused by alignment, a failing mechanism or damaged keeps rather than the handle alone.
The door or window should be assessed as a complete system before repair or replacement work is agreed.

Frequently asked questions
Can a mechanism be repaired instead of replaced?
That depends on the failed component, its condition and the availability of compatible parts.
Why has my door become difficult to lock?
Alignment, hinge movement, worn handles, cylinders or internal mechanism faults can all contribute.
Do you repair both doors and windows?
Yes. Common uPVC and double-glazed door and window hardware problems can be assessed.
