uPVC door fault guide
uPVC door won't close: causes and fixes.
A uPVC door that will not close is usually affected by alignment, dropped hinges, a stiff multipoint lock, worn keeps, a failed handle or seasonal movement. Do not force the handle or key if the mechanism feels jammed, because that can make the repair more expensive. The first job is to check whether the door is catching, whether the lock engages and whether the door is secure.
Short answer
A uPVC door that will not close is usually affected by alignment, dropped hinges, a stiff multipoint lock, worn keeps, a failed handle or seasonal movement. Do not force the handle or key if the mechanism feels jammed, because that can make the repair more expensive. The first job is to check whether the door is catching, whether the lock engages and whether the door is secure.
Factor table
| Symptom | Likely cause | What to do next |
|---|---|---|
| Door catches at the top or bottom | Dropped hinges or frame alignment. | Stop forcing it and send photos of the hinge side. |
| Handle lifts but key will not turn | Multipoint lock not lining up with keeps. | Check whether pushing/pulling changes it; book a repair. |
| Handle feels floppy or stiff | Handle spring, gearbox or mechanism fault. | Avoid repeated force and arrange inspection. |
| Door closes but will not seal | Worn gasket, hinge adjustment or frame movement. | Send photos of the gaps and draught points. |
| Key spins or will not enter | Cylinder or barrel fault. | Ask about barrel/cylinder replacement. |
This guide avoids fake fixed prices. The correct quote depends on the actual fault, access, parts and whether the property is secure.
Why forcing the door is risky
Forcing a stiff handle or key can damage the gearbox, cylinder or multipoint mechanism. A small alignment problem can become a larger lock replacement if the mechanism is put under too much pressure.
Repair before replacement
Many uPVC doors can be recovered with hinge adjustment, keeps, handles, barrels, cylinders, gearboxes or seal work. Full door replacement should only come into the conversation when the slab, frame or security is beyond sensible repair.
Local service note
