Why repair your sliding door in Finchley?
Before you replace a sliding door, it is worth knowing which faults can be put right:
When sending photos of a Finchley door for a repair quote, include any label on the frame edge or spacer bar, because it can help identify the system and its parts.
Before calling out anyone in Finchley for a door that will not lock, check whether the panel has dropped: if the hooks no longer meet the keeps, adjustment may be all it needs.
- A well-maintained, repaired door can give years more service, making a repair a sensible first step when the frame and glass are otherwise sound.
- Repairing or refurbishing a damaged track removes the dips and burrs that make rollers jump, which stops a panel coming off its track.
- Quoting from photos and a short video means many repairs can be priced without a visit, saving time and the diagnostic visit charge for straightforward jobs.

Rules for sliding door repairs in England
Like-for-like repairs such as new rollers, locks, handles or adjustment are not building work under the Building Regulations in England. If the whole door is replaced, it becomes a controlled fitting and the replacement rules apply.
Common repairs and upgrades
- Adjustment and service. Re-aligning panels, cleaning tracks and checking seals and drainage.
- Lock and gearbox replacement. A new mechanism when the handle turns but the door will not lock.
- Roller replacement. New rollers for each sliding panel, restoring a smooth, quiet action.

How can I stop my sliding door needing repairs?
Keeping the track clean is the most effective way to keep a sliding door running well, because grit wears rollers and damages the track surface. Vacuum the track regularly, wipe it with a damp cloth, keep drainage slots clear and avoid slamming panels into their stops. Our maintenance guide has a simple routine.
Why won't my sliding door lock?
A sliding door that will not lock usually has a failed lock gearbox, a worn or broken keep, or a panel that has dropped so the hooks no longer line up with the frame. Forcing the handle can make it worse. Photos of the handle, the lock edge and the frame where the hooks engage usually show which part has failed.
Can a sliding door track be repaired?
A damaged sliding door track can often be repaired or refurbished, depending on the door and how badly the track is worn. On some systems a replacement track cover can be fitted over a worn track, and on others a damaged section can be repaired. If the track is part of a frame that is failing more widely, replacement may be the better option.
