Repair or replace: sliding doors in Crowthorne
Before you replace a sliding door, it is worth knowing which faults can be put right:
Where an older sliding door in Crowthorne 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.
Landlords with properties in Crowthorne can often keep a sound sliding door working with a roller and lock service rather than a full replacement.
- 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.
- 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.
- 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.

How repairs work in Crowthorne
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 RG45 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.
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
- 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 Crowthorne
How quickly can you fix a sliding door in Crowthorne?
We offer a repair date in the RG45 district once you approve the price. Common parts such as rollers and handles can often be fitted on the first visit; specialist parts may need ordering.
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.
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.
