uPVC Door Lock Repairs in South East London

uPVC & Composite Door Specialists

uPVC and composite doors are widely used across South East London and commonly feature multipoint locking systems. However, their internal multipoint locking mechanisms (the parts that engage when you lift the handle) can degrade, wear out, or snap over time.

Common uPVC Door Problems We Fix

• Stiff Handle: The handle is difficult to lift to lock the door. A stiff handle can be caused by door misalignment, the locking mechanism, gearbox or other worn components.
• Floppy Handle: The handle sags downwards and doesn't spring back up. A sagging handle may be caused by worn or broken springs, the spindle, handles or the locking mechanism.
• Key Won't Turn: You can lift the handle, but the key refuses to turn the cylinder to lock it.
• Door Won't Close: The door catches on the frame or the latches don't align with the keeps.
• Jammed Mechanism: The door is locked shut and the handle won't push down to open it.

Our uPVC Repair Solutions

You do not usually need to replace your entire uPVC door when the lock fails. Where possible, replacing only the failed components rather than the entire door or locking system can help keep repair costs down.

• Gearbox Replacement: The central gearbox is the most common point of failure. We carry a selection of commonly used replacement parts, and where the correct gearbox is available the repair may be completed during the same visit.
• Full Multipoint Lock Replacement: If the entire strip is severely damaged or obsolete, we can replace the full locking mechanism.
• Door Alignment (Toe-and-Heeling): If your door has dropped, causing the locks to catch, we can assess and adjust the door, hinges and glazing where appropriate to help restore correct operation.
• Cylinder Upgrades: Upgrade suitable euro cylinders to security-rated anti-snap options to help reduce the risk of lock snapping.
