Common sliding door faults we fix in Great Dunmow
Here is what usually goes wrong with sliding doors, and what can be done about it:
If a sliding door at your Great Dunmow 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 Great Dunmow house leaking at the bottom after heavy rain? Check the drainage slots in the outer frame are clear before assuming a seal has failed.
- Repairing or refurbishing a damaged track removes the dips and burrs that make rollers jump, which stops a panel coming off its track.
- Adjusting a dropped or misaligned panel can cure draughts, rattles and a door that will not close fully against its seals.
- 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.
- Track repair or refurbishment. Repairing damaged track sections, or fitting a new track cover where the system allows.
Questions about sliding door repairs in Great Dunmow
Do you repair sliding doors in Great Dunmow?
Yes. We repair sliding doors in Great Dunmow and across Essex, including nearby Braintree. Send photos or a short video and we will tell you the likely fix and cost before booking a visit.
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.
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 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.
