Reading uPVC Door Lock Service — Gearbox, Cylinder, and Full Mechanism
If your uPVC door in Reading won’t lock, won’t open, or feels wrong when you use the handle, the good news is that most faults are fixable in a single visit. We carry common gearboxes, cylinders, and hardware for the major makes. The RG area is well within our coverage — we also serve Wokingham, Bracknell, Newbury, Basingstoke and surrounding towns.
Diagnosing a uPVC door fault
The diagnosis determines the repair. A cylinder that’s been snapped (a common forced-entry technique) is a straightforward replacement. A gearbox that’s seized or broken internally needs the right replacement gearbox for that specific door brand — they’re not interchangeable. A misalignment problem (where the hooks no longer reach the keeps) is often caused by the door dropping on its hinges, which is an adjustment rather than a lock repair. We test all three possibilities before recommending anything.
Anti-snap upgrade
If we’re replacing a cylinder on any uPVC door, we’ll recommend upgrading to an anti-snap cylinder at the same time. The original cylinders fitted to most uPVC doors from the 1990s and 2000s can be snapped in seconds with basic tools. Anti-snap cylinders have a sacrificial section that breaks off at the snap point, leaving the lock mechanism completely intact and the door still secured. The upgrade costs relatively little on top of a standard cylinder replacement.
