Repair or replace: sliding doors in Hounslow
Before you replace a sliding door, it is worth knowing which faults can be put right:
Where an older sliding door in Hounslow 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.
When sending photos of a Hounslow 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.
- Repairing or refurbishing a damaged track removes the dips and burrs that make rollers jump, which stops a panel coming off its track.
- 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.
- Quoting from photos and a short video means many repairs can be priced without a visit, saving time and the diagnostic visit charge for straightforward jobs.

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
- Roller replacement. New rollers for each sliding panel, restoring a smooth, quiet action.
- Track repair or refurbishment. Repairing damaged track sections, or fitting a new track cover where the system allows.
- Adjustment and service. Re-aligning panels, cleaning tracks and checking seals and drainage.
Questions about sliding door repairs in Hounslow
Do you repair sliding doors in Hounslow?
Yes. We repair sliding doors in Hounslow and across Greater London, including nearby Twickenham. Send photos or a short video and we will tell you the likely fix and cost before booking a visit.
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.
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.
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.
