Repair or replace: sliding doors in Marlborough
Most sliding door problems come down to a handful of worn parts, and a repair is often far cheaper than a new door:
If a sliding door at your Marlborough home has started to drag, clean the bottom track thoroughly before booking anything, as grit alone can cause the problem.
Where an older sliding door in Marlborough 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.
- Adjusting a dropped or misaligned panel can cure draughts, rattles and a door that will not close fully against its seals.
- 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.
- Misted sealed units can usually be replaced individually with new safety glass units, restoring the view and the insulation of that panel.

Booking a sliding door repair in Marlborough
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 SN8 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 Marlborough?
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.
Common repairs and upgrades
- Roller replacement. New rollers for each sliding panel, restoring a smooth, quiet action.
- Track repair or refurbishment. Repairing damaged track sections, or fitting a new track cover where the system allows.
- Handle replacement. Replacing broken or loose handles, including key-lockable versions.
Questions about sliding door repairs in Marlborough
Is it worth repairing an old sliding door in Marlborough?
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.
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.
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.
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.
