Common sliding door faults we fix in Letchworth Garden City
Before you replace a sliding door, it is worth knowing which faults can be put right:
When sending photos of a Letchworth Garden City door for a repair quote, include any label on the frame edge or spacer bar, because it can help identify the system and its parts.
Before calling out anyone in Letchworth Garden City for a door that will not lock, check whether the panel has dropped: if the hooks no longer meet the keeps, adjustment may be all it needs.
- Repairing or refurbishing a damaged track removes the dips and burrs that make rollers jump, which stops a panel coming off its track.
- A new lock gearbox or cylinder restores secure locking when a handle turns but the bolts no longer engage, without replacing the whole door.
- 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.

How repairs work in Letchworth Garden City
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 SG6 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 Letchworth Garden City?
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
- Track repair or refurbishment. Repairing damaged track sections, or fitting a new track cover where the system allows.
- 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 Letchworth Garden City
Is there a call-out charge in Letchworth Garden City?
Many faults can be priced from photos or a short video, so a visit is not always needed. If we need to see the door first, a diagnostic visit costs £95 inc VAT, and we confirm it before we attend. Repair prices include the visit to carry out the repair.
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.
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.
