Repair or replace: sliding doors in Dereham
Most sliding door problems come down to a handful of worn parts, and a repair is often far cheaper than a new door:
Before calling out anyone in Dereham 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.
When sending photos of a Dereham 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.
- 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.
- A new lock gearbox or cylinder restores secure locking when a handle turns but the bolts no longer engage, without replacing the whole door.
- 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 Dereham
Repairs in Dereham 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 Dereham?
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
- Misted unit replacement. A new sealed safety glass unit in place of one that has failed.
- Lock and gearbox replacement. A new mechanism when the handle turns but the door will not lock.
- Track repair or refurbishment. Repairing damaged track sections, or fitting a new track cover where the system allows.
Questions about sliding door repairs in Dereham
How quickly can you fix a sliding door in Dereham?
We offer a repair date in the NR19 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 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.
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.
