Common sliding door faults we fix in Islington
Before you replace a sliding door, it is worth knowing which faults can be put right:
If a sliding door at your Islington home has started to drag, clean the bottom track thoroughly before booking anything, as grit alone can cause the problem.
When sending photos of an Islington 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.
- Misted sealed units can usually be replaced individually with new safety glass units, restoring the view and the insulation of that panel.
- 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 Islington
Send photos or a short video of the fault and we tell you the likely repair and cost before anyone visits. We then book a repair visit in the N1 district at a time that suits you; 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 Islington?
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
- Misted unit replacement. A new sealed safety glass unit in place of one that has failed.
- Handle replacement. Replacing broken or loose handles, including key-lockable versions.
- Roller replacement. New rollers for each sliding panel, restoring a smooth, quiet action.
Questions about sliding door repairs in Islington
Do you repair sliding doors in Islington?
Yes. We repair sliding doors in Islington and across Greater London, including nearby Highbury. 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.
Can a sliding door track be repaired?
A damaged sliding door track can often be repaired or refurbished, depending on the door and how badly the track is worn. On some systems a replacement track cover can be fitted over a worn track, and on others a damaged section can be repaired. If the track is part of a frame that is failing more widely, replacement may be the better option.
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.
