How a lock repair works

  1. 1. Diagnose

    We find whether the fault is the cylinder, gearbox, full multipoint strip or door alignment.

  2. 2. Replace

    Worn parts are swapped with matched hardware — including anti-snap cylinders if you want an upgrade.

  3. 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.

Why window & door lock repair problems happen in Kingsthorpe

Slamming and heavy use

Busy front and back doors get slammed and leant on daily, loosening handles and fixing screws over time.

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.

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.
