UPVC door not closing, locking, or operating properly? Our technicians repair and replace multipoint lock mechanisms, handles, cylinders, and hinges across Kennington and SE11 — fast, same-day service.
UPVC doors are the most common door type in London and account for a large proportion of our repair work across Kennington and SE11. While durable, UPVC multipoint locking systems contain complex mechanical components that can wear, fail, or suffer damage — leaving the door impossible to lock, difficult to open, or insecure.
The most common UPVC door problem we encounter is a failed multipoint gearbox — the internal mechanism that coordinates all the locking points on the door when you lift the handle and turn the key. When this gearbox fails, the door either won't lock, won't unlock, or the handle droops and no longer operates the lock correctly.
We carry a comprehensive stock of replacement multipoint lock gearboxes, hooks, rollers, and keeps for all major UPVC door brands including Mila, Winkhaus, Yale, Fullex, Lockmaster, Era, and Avantis. In most cases, we can repair your UPVC door on the same visit.
We also repair and replace UPVC door handles, euro cylinder locks, letter box fittings, and door hinges. If your UPVC door is dropping, dragging on the frame, or not closing properly, hinge adjustment or replacement is often the solution.
The internal multipoint mechanism is the most common failure point on UPVC doors. We stock and fit replacement gearboxes for all major brands.
Broken, sagging, or seized UPVC door handle? We replace handles and spindles for all UPVC and composite door types.
Anti-snap euro cylinder replacement for UPVC doors — we strongly recommend upgrading to an anti-snap cylinder for improved security.
UPVC door dropping, dragging, or not closing squarely? We adjust and replace butt hinges, flag hinges, and concealed hinges.
Misaligned UPVC door making it difficult to close or lock? We re-align the door within the frame to restore smooth, secure operation.
We also repair composite doors — the same multipoint mechanisms and cylinder locks are used, and we carry the necessary replacement parts.
Don't just take our word for it — here's what our local customers say about Lockstar Locksmith Kennington.
