Why repair your sliding door in Lisburn?
Here is what usually goes wrong with sliding doors, and what can be done about it:
Is the patio door in your Lisburn house leaking at the bottom after heavy rain? Check the drainage slots in the outer frame are clear before assuming a seal has failed.
If a sliding door at your Lisburn home has started to drag, clean the bottom track thoroughly before booking anything, as grit alone can cause the problem.
- Where a repair is not worth doing, for example because parts are unavailable, we say so plainly rather than fitting parts that will not last.
- 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.

Questions about sliding door repairs in Lisburn
Do you repair sliding doors in Lisburn?
Yes. We repair sliding doors in Lisburn and across County Antrim, including nearby Belfast. Send photos or a short video and we will tell you the likely fix and cost before booking a visit.
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.
Is it worth repairing an old sliding patio door?
Repairing an old sliding patio door is worth it if the frame and glass are sound and the parts are available, because a few new rollers or a lock can restore it for a fraction of the cost of replacement. If the frame is failing, the door is single glazed or parts are discontinued, replacement usually makes more sense.
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.
