Common sliding door faults we fix in Wellingborough
Here is what usually goes wrong with sliding doors, and what can be done about it:
Where an older sliding door in Wellingborough 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 Wellingborough can often keep a sound sliding door working with a roller and lock service rather than a full replacement.
- 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.
- 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.

How repairs work in Wellingborough
Repairs in Wellingborough start with photos or, if needed, a diagnostic visit. Once you approve the price we book the repair: most repairs are booked within a few weeks, parts permitting, and specialist parts are ordered where needed.
Do you need approval in Wellingborough?
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.
What we can repair
- Misted unit replacement. A new sealed safety glass unit in place of one that has failed.
- Adjustment and service. Re-aligning panels, cleaning tracks and checking seals and drainage.
- Handle replacement. Replacing broken or loose handles, including key-lockable versions.
Questions about sliding door repairs in Wellingborough
Is it worth repairing an old sliding door in Wellingborough?
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.
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.
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.
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.
