Repair or replace: sliding doors in Towcester
Here is what usually goes wrong with sliding doors, and what can be done about it:
Is the patio door in your Towcester house leaking at the bottom after heavy rain? Check the drainage slots in the outer frame are clear before assuming a seal has failed.
Before calling out anyone in Towcester 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.
- Adjusting a dropped or misaligned panel can cure draughts, rattles and a door that will not close fully against its seals.
- Repairing or refurbishing a damaged track removes the dips and burrs that make rollers jump, which stops a panel coming off its track.
- 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
Like-for-like repairs such as new rollers, locks, handles or adjustment are not building work under the Building Regulations in England. If the whole door is replaced, it becomes a controlled fitting and the replacement rules apply.
Repairs and upgrades to consider
- Adjustment and service. Re-aligning panels, cleaning tracks and checking seals and drainage.
- Handle replacement. Replacing broken or loose handles, including key-lockable versions.
- Lock and gearbox replacement. A new mechanism when the handle turns but the door will not lock.
Questions about sliding door repairs in Towcester
Do you repair sliding doors in Towcester?
Yes. We repair sliding doors in Towcester and across Northamptonshire, including nearby Northampton. Send photos or a short video and we will tell you the likely fix and cost before booking a visit.
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.
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.
