Sliding door repairs in Carshalton: what to know
Here is what usually goes wrong with sliding doors, and what can be done about it:
Is the patio door in your Carshalton house leaking at the bottom after heavy rain? Check the drainage slots in the outer frame are clear before assuming a seal has failed.
If a sliding door at your Carshalton home has started to drag, clean the bottom track thoroughly before booking anything, as grit alone can cause the problem.
- 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.
- Adjusting a dropped or misaligned panel can cure draughts, rattles and a door that will not close fully against its seals.
- 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.

Booking a sliding door repair in Carshalton
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 SM5 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
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.
- Handle replacement. Replacing broken or loose handles, including key-lockable versions.
- Track repair or refurbishment. Repairing damaged track sections, or fitting a new track cover where the system allows.
Questions about sliding door repairs in Carshalton
Do you repair sliding doors in Carshalton?
Yes. We repair sliding doors in Carshalton and across Greater London, including nearby Sutton. 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.
Can you replace misted glass in a sliding door?
Yes, a misted sealed unit in a sliding door can usually be replaced on its own without changing the frame. The new unit is made to the size of the old one in safety glass, as glass in doors must be, and fitted into the existing panel. It is worth checking whether the frame is still sound first.
