Sliding door repairs in Greenwich: what to know
Most sliding door problems come down to a handful of worn parts, and a repair is often far cheaper than a new door:
If a sliding door at your Greenwich home has started to drag, clean the bottom track thoroughly before booking anything, as grit alone can cause the problem.
Before calling out anyone in Greenwich 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.
- Where a repair is not worth doing, for example because parts are unavailable, we say so plainly rather than fitting parts that will not last.
- Adjusting a dropped or misaligned panel can cure draughts, rattles and a door that will not close fully against its seals.
- Misted sealed units can usually be replaced individually with new safety glass units, restoring the view and the insulation of that panel.

From photos to fixed door in Greenwich
We repair sliding doors in Greenwich and nearby Blackheath and Lewisham. 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 Greenwich?
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
- Misted unit replacement. A new sealed safety glass unit in place of one that has failed.
- Roller replacement. New rollers for each sliding panel, restoring a smooth, quiet action.
- Handle replacement. Replacing broken or loose handles, including key-lockable versions.
Questions about sliding door repairs in Greenwich
Is it worth repairing an old sliding door in Greenwich?
Often, yes. New rollers, a lock gearbox or a track refurbishment cost a fraction of a new door. If the frame is twisted or the door fails on thermal performance, we will say so and price a replacement instead.
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.
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.
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.
