Repair or replace: sliding doors in Heathfield
Before you replace a sliding door, it is worth knowing which faults can be put right:
Landlords with properties in Heathfield can often keep a sound sliding door working with a roller and lock service rather than a full replacement.
Where an older sliding door in Heathfield 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.
- 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.
- Misted sealed units can usually be replaced individually with new safety glass units, restoring the view and the insulation of that panel.
- 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.
What we can repair
- Roller replacement. New rollers for each sliding panel, restoring a smooth, quiet action.
- Lock and gearbox replacement. A new mechanism when the handle turns but the door will not lock.
- Misted unit replacement. A new sealed safety glass unit in place of one that has failed.
Questions about sliding door repairs in Heathfield
Is it worth repairing an old sliding door in Heathfield?
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.
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.
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 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.
