Repair or replace: sliding doors in Crawley
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 Crawley 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.
Landlords with properties in Crawley can often keep a sound sliding door working with a roller and lock service rather than a full replacement.
- Misted sealed units can usually be replaced individually with new safety glass units, restoring the view and the insulation of that panel.
- 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.

Booking a sliding door repair in Crawley
We repair sliding doors in Crawley and nearby Horley and Horsham. You approve the price first, then we book the visit; most repairs are completed in a single visit, unless parts need ordering or a new glass unit must be made.
Do you need approval in Crawley?
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
- Track repair or refurbishment. Repairing damaged track sections, or fitting a new track cover where the system allows.
- Adjustment and service. Re-aligning panels, cleaning tracks and checking seals and drainage.
- Lock and gearbox replacement. A new mechanism when the handle turns but the door will not lock.
Questions about sliding door repairs in Crawley
Do you repair sliding doors in Crawley?
Yes. We repair sliding doors in Crawley and across West Sussex, including nearby Horley. Send photos or a short video and we will tell you the likely fix and cost before booking a visit.
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 there a free survey for sliding door repairs?
No, our free survey applies to new doors and replacements only. Repairs are quoted from photos and a short video you send us, or after a diagnostic visit where photos are not enough. If a visit is needed, the diagnostic visit costs £95 inc VAT and is confirmed before we attend, so you know where you stand.
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.
