Why repair your sliding door in Tonbridge?
Here is what usually goes wrong with sliding doors, and what can be done about it:
When sending photos of a Tonbridge 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.
Before calling out anyone in Tonbridge 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.
- 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.
- 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.
- 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 Tonbridge
We repair sliding doors in Tonbridge and nearby Royal Tunbridge Wells and Sevenoaks. 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 Tonbridge?
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.
What we can repair
- 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.
- Misted unit replacement. A new sealed safety glass unit in place of one that has failed.
Questions about sliding door repairs in Tonbridge
Is there a call-out charge in Tonbridge?
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.
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 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.
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.
