UPVC door won't lock or is misaligned? SIDE Locksmiths specialise in multipoint lock repairs, mechanism replacement, and door adjustment across South Yorkshire.
UPVC and composite doors are common across Sheffield and South Yorkshire, and their multipoint locking mechanisms can fail over time. If your UPVC door won't lock properly, the handle is stiff, or the door has dropped and become misaligned, SIDE Locksmiths can diagnose and repair the issue quickly and professionally.
We specialise in all aspects of UPVC door lock repair, including multipoint locking mechanism replacement, gearbox repairs, cylinder changes, handle and hinge adjustment, and door realignment. We carry common replacement parts in our van, including gearboxes and multipoint strip mechanisms for popular brands like Yale, Mila, Maco, GU, and Winkhaus — so most repairs can be completed on the first visit.
A common issue with UPVC doors is that the door drops over time, causing the multipoint locking points to misalign with the keeps on the frame. This makes the door difficult to lock and can eventually cause the mechanism to fail completely. Our locksmiths can realign the door and adjust the hinges to restore smooth operation, often without needing to replace the entire mechanism.
If your multipoint lock mechanism has failed completely, we can replace the full locking strip and gearbox. We always provide a fixed quote before starting any work, and we'll explain all available options — including whether a repair or full replacement is the most cost-effective solution for your door.
