Repair or replace: sliding doors in Sydenham
Most sliding door problems come down to a handful of worn parts, and a repair is often far cheaper than a new door:
Where an older sliding door in Sydenham 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.
If a sliding door at your Sydenham home has started to drag, clean the bottom track thoroughly before booking anything, as grit alone can cause the problem.
- 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.

Booking a sliding door repair in Sydenham
Send photos or a short video of the fault and we tell you the likely repair and cost before anyone visits. We then book a repair visit in the SE26 district at a time that suits you; most repairs are completed in a single visit, unless parts need ordering or a new glass unit must be made.
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.
Common repairs and upgrades
- 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 Sydenham
Is there a call-out charge in Sydenham?
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.
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.
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.
