Why repair your sliding door in Derry/Londonderry?
Here is what usually goes wrong with sliding doors, and what can be done about it:
Landlords with properties in Derry/Londonderry can often keep a sound sliding door working with a roller and lock service rather than a full replacement.
Is the patio door in your Derry/Londonderry house leaking at the bottom after heavy rain? Check the drainage slots in the outer frame are clear before assuming a seal has failed.
- 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.
- A new lock gearbox or cylinder restores secure locking when a handle turns but the bolts no longer engage, without replacing the whole door.
- Repairing or refurbishing a damaged track removes the dips and burrs that make rollers jump, which stops a panel coming off its track.

Questions about sliding door repairs in Derry/Londonderry
Do you repair sliding doors in Derry/Londonderry?
Yes. We repair sliding doors in Derry/Londonderry and across County Londonderry, including nearby Strabane. Send photos or a short video and we will tell you the likely fix and cost before booking a visit.
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.
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 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.
