DOOR & LOCK REPAIRS

uPVC & Composite Door Lock Repair London

Having trouble locking, unlocking or closing a uPVC or composite door? We diagnose door alignment, cylinder and multipoint locking problems across London.

Modern uPVC and composite doors often use a multipoint locking system. When something goes wrong, the symptoms can look similar even though the cause may be very different. A dropped door, worn gearbox, cylinder fault, damaged handle or poor alignment can all make a door difficult to lock.

COMMON PROBLEMS

Stiff Handles, Dropped Doors & Failed Locks

We assess doors that need lifting to lock, stiff handles, failed cylinders, multipoint locking faults and doors that have dropped out of alignment.

Handle Has Gone StiffResistance when lifting or lowering the handle can point to alignment or mechanism strain→Door Needs Lifting to LockA common sign that the door and locking points are no longer aligned correctly→Key Won’t Turn ProperlyWe check the cylinder, mechanism and door position before replacing parts→Multipoint Lock Has FailedHooks, bolts or the gearbox may no longer engage or retract correctly→Door Is Catching the FrameDropped or shifted doors can place unnecessary pressure on the lock→Door Is Jammed ShutUrgent access when the door will no longer open normally→

Don’t keep forcing a stiff handle. Send us your postcode and photos of the full door, handles and lock faceplate. Tell us whether the problem happens with the door open, closed or both. That helps separate an alignment problem from a failed locking component.

Warning signs include a handle becoming increasingly stiff, the key only turning when you push or pull the door, the door catching the frame, difficulty engaging the hooks or bolts, or a mechanism that suddenly stops operating. Continuing to force a stiff mechanism can sometimes turn an adjustment issue into a failed component.

DIAGNOSE FIRST

Repair Before Replacement Where Appropriate

A locking problem does not automatically mean the complete mechanism needs replacing. We diagnose the cause first and repair or realign the door where that is the appropriate solution.

Door Alignment & Adjustment

Doors can move through regular use, temperature changes or hinge movement. When locking points no longer line up with the frame, correcting the alignment can restore smooth operation and reduce strain on the mechanism.

Door alignment and warranty: Door and frame alignment may change over time due to temperature fluctuations, changing weather conditions and the natural expansion, contraction or movement of surrounding materials. As these factors are outside our control, we do not offer a warranty against a door becoming misaligned again following adjustment. This does not affect your statutory consumer rights in relation to the work carried out.

Has the Multipoint Lock Failed?

If the mechanism has failed, we identify the affected component first. The problem may be the gearbox, hooks, bolts or another part of the multipoint system rather than the entire lock assembly.

Could It Be the Cylinder or Handles?

Euro cylinders and door handles can produce similar symptoms to a mechanism fault. We check how the components interact before recommending replacement so only the parts actually required are changed.

What Should I Send on WhatsApp?

Send the full door, handles, lock faceplate on the door edge and any visible branding. Tell us whether the door is open or closed and exactly what happens when you lift the handle or turn the key.
