Sliding door repairs in Derby: what to know
Here is what usually goes wrong with sliding doors, and what can be done about it:
Before calling out anyone in Derby 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.
If a sliding door at your Derby home has started to drag, clean the bottom track thoroughly before booking anything, as grit alone can cause the problem.
- A new lock gearbox or cylinder restores secure locking when a handle turns but the bolts no longer engage, without replacing the whole door.
- 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.
- Repairing or refurbishing a damaged track removes the dips and burrs that make rollers jump, which stops a panel coming off its track.

Do you need approval in Derby?
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.

- Adjustment and service. Re-aligning panels, cleaning tracks and checking seals and drainage.
- Misted unit replacement. A new sealed safety glass unit in place of one that has failed.

Questions about sliding door repairs in Derby
Is there a call-out charge in Derby?
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.
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.
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.
