Repair or replace: sliding doors in Barnard Castle
Most sliding door problems come down to a handful of worn parts, and a repair is often far cheaper than a new door:
Is the patio door in your Barnard Castle house leaking at the bottom after heavy rain? Check the drainage slots in the outer frame are clear before assuming a seal has failed.
Before calling out anyone in Barnard Castle 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.
- Repairing or refurbishing a damaged track removes the dips and burrs that make rollers jump, which stops a panel coming off its track.
- Adjusting a dropped or misaligned panel can cure draughts, rattles and a door that will not close fully against its seals.
- A new lock gearbox or cylinder restores secure locking when a handle turns but the bolts no longer engage, without replacing the whole door.

Questions about sliding door repairs in Barnard Castle
Is it worth repairing an old sliding door in Barnard Castle?
Often, yes. New rollers, a lock gearbox or a track refurbishment cost a fraction of a new door. If the frame is twisted or the door fails on thermal performance, we will say so and price a replacement instead.
Is there a free survey for sliding door repairs?
No, our free survey applies to new doors and replacements only. Repairs are quoted from photos and a short video you send us, or after a diagnostic visit where photos are not enough. If a visit is needed, the diagnostic visit costs £95 inc VAT and is confirmed before we attend, so you know where you stand.
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.
