Common sliding door faults we fix in Chislehurst
Before you replace a sliding door, it is worth knowing which faults can be put right:
Where an older sliding door in Chislehurst has several faults at once, such as misted glass, worn rollers and a failing lock, compare the total repair cost with a replacement before deciding.
When sending photos of a Chislehurst 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.
- A new lock gearbox or cylinder restores secure locking when a handle turns but the bolts no longer engage, without replacing the whole door.
- Repairing or refurbishing a damaged track removes the dips and burrs that make rollers jump, which stops a panel coming off its track.

How repairs work in Chislehurst
We repair sliding doors in Chislehurst and nearby Sidcup and Bromley. 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 Chislehurst?
Repairs are generally outside the Building Regulations in England. Any replacement glass we fit in a door is safety glazing, in line with Approved Document K, and if the door needs replacing rather than repairing, the controlled-fitting rules apply.
Repairs and upgrades to consider
- Misted unit replacement. A new sealed safety glass unit in place of one that has failed.
- 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 Chislehurst
Do you repair sliding doors in Chislehurst?
Yes. We repair sliding doors in Chislehurst and across Greater London, including nearby Sidcup. Send photos or a short video and we will tell you the likely fix and cost before booking a visit.
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.
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.
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.
