Sliding door repairs in New Malden: what to know
Before you replace a sliding door, it is worth knowing which faults can be put right:
Where an older sliding door in New Malden 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.
If a sliding door at your New Malden home has started to drag, clean the bottom track thoroughly before booking anything, as grit alone can cause the problem.
- 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.
- 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.
- 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.

From photos to fixed door in New Malden
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 KT3 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.
- Handle replacement. Replacing broken or loose handles, including key-lockable versions.
- Adjustment and service. Re-aligning panels, cleaning tracks and checking seals and drainage.
Questions about sliding door repairs in New Malden
How quickly can you fix a sliding door in New Malden?
We offer a repair date in the KT3 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.
Is there a free survey for sliding door repairs?
No, our free survey applies to new doors and replacements only. Repairs are quoted from photos and a short video you send us, or after a diagnostic visit where photos are not enough. If a visit is needed, the diagnostic visit costs £95 inc VAT and is confirmed before we attend, so you know where you stand.
Is it worth repairing an old sliding patio door?
Repairing an old sliding patio door is worth it if the frame and glass are sound and the parts are available, because a few new rollers or a lock can restore it for a fraction of the cost of replacement. If the frame is failing, the door is single glazed or parts are discontinued, replacement usually makes more sense.
