Common sliding door faults we fix in Farnham
Most sliding door problems come down to a handful of worn parts, and a repair is often far cheaper than a new door:
Before calling out anyone in Farnham for a door that will not lock, check whether the panel has dropped: if the hooks no longer meet the keeps, adjustment may be all it needs.
When sending photos of a Farnham 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.
- Repairing or refurbishing a damaged track removes the dips and burrs that make rollers jump, which stops a panel coming off its track.
- 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.
- 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.

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.
Common repairs and upgrades
- Misted unit replacement. A new sealed safety glass unit in place of one that has failed.
- Lock and gearbox replacement. A new mechanism when the handle turns but the door will not lock.
- Handle replacement. Replacing broken or loose handles, including key-lockable versions.
Questions about sliding door repairs in Farnham
Is there a call-out charge in Farnham?
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.
How can I stop my sliding door needing repairs?
Keeping the track clean is the most effective way to keep a sliding door running well, because grit wears rollers and damages the track surface. Vacuum the track regularly, wipe it with a damp cloth, keep drainage slots clear and avoid slamming panels into their stops. Our maintenance guide has a simple routine.
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.
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.
