Common sliding door faults we fix in Dumbarton
Here is what usually goes wrong with sliding doors, and what can be done about it:
Where an older sliding door in Dumbarton 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.
Landlords with properties in Dumbarton can often keep a sound sliding door working with a roller and lock service rather than a full replacement.
- Repairing or refurbishing a damaged track removes the dips and burrs that make rollers jump, which stops a panel coming off its track.
- 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.
- 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.

Questions about sliding door repairs in Dumbarton
Is there a call-out charge in Dumbarton?
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.
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.
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.
What photos should I send for a repair quote?
Send a photo of the whole door from inside, close-ups of the handle, the lock edge and the bottom track, and any label or marking on the frame or glass spacer. A short video of the door opening and closing is especially helpful. Tell us roughly how old the door is and what it is doing wrong.
