uPVC Door Repairs & Mechanism Replacement
Is your uPVC door difficult to lock? Does the handle lift but the key won't turn? Perhaps the door is catching on the frame or won't open at all.
At Gavin the Locksmith, I specialise in uPVC door repairs and mechanism replacements across Middlesbrough, Stockton-on-Tees, Redcar, Hartlepool and the wider Teesside area.
Common uPVC Door Problems
uPVC doors are designed to provide years of reliable service, but over time components can wear out, become misaligned or fail completely.
Some of the most common issues I repair include:
* Door won't lock properly
* Key difficult to turn
* Door handle feels loose or floppy
* Multi-point locking mechanism failure
* Door catching on the frame
* Broken gearbox
* Snapped or worn euro cylinder
* Door stuck locked shut
* Handles that won't return correctly
* Misaligned doors causing locking problems
uPVC Mechanism Replacement
Many customers are told they need a new door when the real problem is a failed locking mechanism.
In many cases, the existing door can be repaired by replacing the faulty mechanism, gearbox or locking strip, saving hundreds of pounds compared to a full door replacement.
I carry a wide range of replacement mechanisms and can source parts for many popular door systems, including older models that can be difficult to identify.
Fix If Possible, Replace If Needed
My approach is simple: if the door can be repaired, I'll repair it.
I regularly attend jobs where homeowners have been advised to replace an entire door when only a small component has failed. A professional repair can often restore the door to full working order for a fraction of the cost.
