UPVC Door Lock Repair · Dulwich & South London
UPVC Door Lock Repair in Dulwich & South London — From £75
UPVC door lock failures are the single most common call we receive. The multipoint mechanism — the gearbox, hooks, rollers and deadbolts driven by the handle — works hard every day, and after years of service the gearbox wears, the door drops on its hinges, or the alignment drifts. The symptoms are unmistakable: you have to lift the handle with force, slam the door to lock it, or the key won't turn fully.
Unlike a general handyman, we diagnose the specific failure point rather than replacing parts blindly. Is it the gearbox, a failed locking point, or simply a dropped door needing realignment? Getting the diagnosis right is the difference between a £95 gearbox replacement and an unnecessary £400 mechanism swap — and we carry the range to fix it in one visit.
What's included
- Multipoint gearbox diagnosis and replacement (ERA, Fullex, Avocet, Mila, Fuhr)
- Dropped-handle and non-engaging-bolt faults
- Full mechanism replacement where the gearbox has damaged the strip
- Door realignment and hinge adjustment
- Snapped-key extraction from UPVC cylinders
- Anti-snap cylinder upgrades fitted at the same time

UPVC Door Lock Repair — FAQs
My UPVC door handle has dropped and the door won't lock — what does that mean?
Almost always a failed multipoint gearbox. The handle drops because the spring mechanism inside the gearbox has broken, and without it the bolts won't engage. It's our most common UPVC fault and we can usually replace the gearbox in a single visit from £95 including parts.
Do I need a whole new door if the lock mechanism fails?
No — this is the good news. The door itself is almost never the problem. The locking mechanism is a replaceable component, and replacing the gearbox or full strip costs a fraction of a new door.
How do I stop my UPVC door lock failing again?
Lift the handle fully every time you lock — engaging all the locking points spreads the load across the mechanism instead of straining the gearbox. And don't force a stiff handle; that's the early warning. A quick service visit is far cheaper than a failed gearbox.
