Are sliding door repairs right for homes in County Antrim?
Before you replace a sliding door, it is worth knowing which faults can be put right:
Is the patio door in your County Antrim house leaking at the bottom after heavy rain? Check the drainage slots in the outer frame are clear before assuming a seal has failed.
Landlords with properties in County Antrim can often keep a sound sliding door working with a roller and lock service rather than a full replacement.
- 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.
- A new lock gearbox or cylinder restores secure locking when a handle turns but the bolts no longer engage, without replacing the whole door.
- 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.

Questions about sliding door repairs in County Antrim
Is there a call-out charge in County Antrim?
Many faults can be priced from photos or a short video, so a visit is not always needed. If we need to see the door first, a diagnostic visit costs £95 inc VAT, and we confirm it before we attend. Repair prices include the visit to carry out the repair.
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.
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.
