Emergency UPVC repairs
Sound Familiar?
"It won't lock all the way"
The locking points aren't engaging properly — usually a worn gearbox, a dropped door, or a misaligned frame. We diagnose and fix it, often the same day.
"The handle's gone floppy"
A droopy handle means the internal spindle or springs have failed and the lock mechanism is under strain. New springs or a full handle set replacement sorts it quickly.
"The key's stuck or won't turn"
Could be a seized cylinder or a failed mechanism behind it. We open the door without damage and replace what's needed — we always recommend upgrading to an anti-snap cylinder while we're there.
"The door's dropped and won't close properly"
Worn or damaged hinges cause doors to drop, preventing proper locking. We adjust, repair, or replace hinges to restore correct alignment and full locking function.
"It locks but won't unlock"
Internal mechanism failure can trap you inside or prevent you from opening the door. We diagnose and fix internal UPVC failures safely and quickly.

Why UPVC Mechanisms Fail
UPVC and composite doors use complex multipoint locking mechanisms with multiple moving parts. Over time, the internal gearbox wears, the door drops on its hinges causing misalignment, or the spindle connecting the handle to the mechanism breaks. When any component fails the whole system can stop working.
The good news is that in the vast majority of cases the door itself is fine — only the mechanism, handle, or cylinder needs replacing. This is far cheaper than replacing the whole door and we complete it on the same visit in most cases.
