Why repair your sliding door in Coleraine?
Most sliding door problems come down to a handful of worn parts, and a repair is often far cheaper than a new door:
If a sliding door at your Coleraine home has started to drag, clean the bottom track thoroughly before booking anything, as grit alone can cause the problem.
Is the patio door in your Coleraine house leaking at the bottom after heavy rain? Check the drainage slots in the outer frame are clear before assuming a seal has failed.
- 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.
- 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.

Questions about sliding door repairs in Coleraine
Do you repair sliding doors in Coleraine?
Yes. We repair sliding doors in Coleraine and across County Londonderry, including nearby Portstewart. Send photos or a short video and we will tell you the likely fix and cost before booking a visit.
Can you replace misted glass in a sliding door?
Yes, a misted sealed unit in a sliding door can usually be replaced on its own without changing the frame. The new unit is made to the size of the old one in safety glass, as glass in doors must be, and fitted into the existing panel. It is worth checking whether the frame is still sound first.
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.
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.
