How a lock repair works
1. Diagnose
We find whether the fault is the cylinder, gearbox, full multipoint strip or door alignment.
2. Replace
Worn parts are swapped with matched hardware — including anti-snap cylinders if you want an upgrade.
3. Test
We adjust keeps and test every locking point so the door opens and locks smoothly.
Most lock faults are fixed by replacing a single part, not the whole door — and we carry common gearboxes and cylinders on the van.
What causes the problem — common faults we see in St James
Worn gearbox
The gearbox inside a uPVC door turns every handle movement into lock movement. Thousands of uses later, its internal parts wear and slip.
Seasonal swelling
uPVC and composite doors expand in hot weather. A door that locks fine in winter can become tight in summer and stress the lock.
Door dropping out of line
When hinges wear, the door sags and the locking hooks no longer meet the keeps. Forcing the handle up then strains the gearbox until it breaks.
