Why repair your sliding door in Newhaven?
Here is what usually goes wrong with sliding doors, and what can be done about it:
Is the patio door in your Newhaven house leaking at the bottom after heavy rain? Check the drainage slots in the outer frame are clear before assuming a seal has failed.
Where an older sliding door in Newhaven 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.
- 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.
- Repairing or refurbishing a damaged track removes the dips and burrs that make rollers jump, which stops a panel coming off its track.
- Misted sealed units can usually be replaced individually with new safety glass units, restoring the view and the insulation of that panel.

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.
Common repairs and upgrades
- 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.
- Track repair or refurbishment. Repairing damaged track sections, or fitting a new track cover where the system allows.
Questions about sliding door repairs in Newhaven
Is it worth repairing an old sliding door in Newhaven?
Often, yes. New rollers, a lock gearbox or a track refurbishment cost a fraction of a new door. If the frame is twisted or the door fails on thermal performance, we will say so and price a replacement instead.
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.
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.
How do I know if my sliding door rollers need replacing?
Sliding door rollers usually need replacing when the panel becomes hard to push, rumbles or grinds as it moves, sits lower at one end or jumps off the track. Cleaning the track first is worth trying, because grit can cause similar symptoms. If the door is still heavy once the track is clean, the rollers are likely worn or broken.
