Sliding door repairs across Gwynedd
Before you replace a sliding door, it is worth knowing which faults can be put right:
Is the patio door in your Gwynedd 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 Gwynedd 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.
- A new lock gearbox or cylinder restores secure locking when a handle turns but the bolts no longer engage, without replacing the whole door.
- 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.

Questions about sliding door repairs in Gwynedd
How quickly can you fix a sliding door in Gwynedd?
We offer a repair date in Gwynedd once you approve the price. Common parts such as rollers and handles can often be fitted on the first visit; specialist parts may need ordering.
What photos should I send for a repair quote?
Send a photo of the whole door from inside, close-ups of the handle, the lock edge and the bottom track, and any label or marking on the frame or glass spacer. A short video of the door opening and closing is especially helpful. Tell us roughly how old the door is and what it is doing wrong.
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.
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.
