Common sliding door faults we fix in Dover
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 Dover 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 Dover can often keep a sound sliding door working with a roller and lock service rather than a full replacement.
- 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.
- 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.

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
- Adjustment and service. Re-aligning panels, cleaning tracks and checking seals and drainage.
- Track repair or refurbishment. Repairing damaged track sections, or fitting a new track cover where the system allows.
- Handle replacement. Replacing broken or loose handles, including key-lockable versions.
Questions about sliding door repairs in Dover
Do you repair sliding doors in Dover?
Yes. We repair sliding doors in Dover and across Kent, including nearby Folkestone. 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 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.
