Why repair your sliding door in Dungiven?
Before you replace a sliding door, it is worth knowing which faults can be put right:
Where an older sliding door in Dungiven has several faults at once, such as misted glass, worn rollers and a failing lock, compare the total repair cost with a replacement before deciding.
When sending photos of a Dungiven 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.
- 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.
- Replacing worn rollers is often enough to bring back the light, smooth action of a sliding panel that has become heavy and noisy to open.
- 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 Dungiven
Do you repair sliding doors in Dungiven?
Yes. We repair sliding doors in Dungiven and across County Londonderry, including nearby Limavady. 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 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.
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.
