Common sliding door faults we fix in Truro
Before you replace a sliding door, it is worth knowing which faults can be put right:
If a sliding door at your Truro 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 Truro 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.
- Adjusting a dropped or misaligned panel can cure draughts, rattles and a door that will not close fully against its seals.
- 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.

Rules for sliding door repairs in England
Like-for-like repairs such as new rollers, locks, handles or adjustment are not building work under the Building Regulations in England. If the whole door is replaced, it becomes a controlled fitting and the replacement rules apply.
Repairs and upgrades to consider
- Roller replacement. New rollers for each sliding panel, restoring a smooth, quiet action.
- Track repair or refurbishment. Repairing damaged track sections, or fitting a new track cover where the system allows.
- Lock and gearbox replacement. A new mechanism when the handle turns but the door will not lock.
Questions about sliding door repairs in Truro
Do you repair sliding doors in Truro?
Yes. We repair sliding doors in Truro and across Cornwall, including nearby Falmouth. Send photos or a short video and we will tell you the likely fix and cost before booking a visit.
How do I know if my sliding door rollers need replacing?
Sliding door rollers usually need replacing when the panel becomes hard to push, rumbles or grinds as it moves, sits lower at one end or jumps off the track. Cleaning the track first is worth trying, because grit can cause similar symptoms. If the door is still heavy once the track is clean, the rollers are likely worn or broken.
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.
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.
