Sliding door repairs in Dunstable: what to know
Before you replace a sliding door, it is worth knowing which faults can be put right:
If a sliding door at your Dunstable 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 Dunstable 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.
- 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.
- 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.
- Misted sealed units can usually be replaced individually with new safety glass units, restoring the view and the insulation of that panel.

How repairs work in Dunstable
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 LU6 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
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.
Repairs and upgrades to consider
- 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.
- Adjustment and service. Re-aligning panels, cleaning tracks and checking seals and drainage.
Questions about sliding door repairs in Dunstable
How quickly can you fix a sliding door in Dunstable?
We offer a repair date in the LU6 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.
What photos should I send for a repair quote?
Send a photo of the whole door from inside, close-ups of the handle, the lock edge and the bottom track, and any label or marking on the frame or glass spacer. A short video of the door opening and closing is especially helpful. Tell us roughly how old the door is and what it is doing wrong.
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.
How can I stop my sliding door needing repairs?
Keeping the track clean is the most effective way to keep a sliding door running well, because grit wears rollers and damages the track surface. Vacuum the track regularly, wipe it with a damp cloth, keep drainage slots clear and avoid slamming panels into their stops. Our maintenance guide has a simple routine.
