Common sliding door faults we fix in Farnborough
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 Farnborough home has started to drag, clean the bottom track thoroughly before booking anything, as grit alone can cause the problem.
When sending photos of a Farnborough door for a repair quote, include any label on the frame edge or spacer bar, because it can help identify the system and its parts.
- 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.
- Misted sealed units can usually be replaced individually with new safety glass units, restoring the view and the insulation of that panel.
- A new lock gearbox or cylinder restores secure locking when a handle turns but the bolts no longer engage, without replacing the whole door.

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.
What we can repair
- Handle replacement. Replacing broken or loose handles, including key-lockable versions.
- Lock and gearbox replacement. A new mechanism when the handle turns but the door will not lock.
- Roller replacement. New rollers for each sliding panel, restoring a smooth, quiet action.
Questions about sliding door repairs in Farnborough
Is it worth repairing an old sliding door in Farnborough?
Often, yes. New rollers, a lock gearbox or a track refurbishment cost a fraction of a new door. If the frame is twisted or the door fails on thermal performance, we will say so and price a replacement instead.
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.
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.
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.
