Repair or replace: sliding doors in Sudbury
Before you replace a sliding door, it is worth knowing which faults can be put right:
Is the patio door in your Sudbury house leaking at the bottom after heavy rain? Check the drainage slots in the outer frame are clear before assuming a seal has failed.
When sending photos of a Sudbury 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.
- 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.
- Adjusting a dropped or misaligned panel can cure draughts, rattles and a door that will not close fully against its seals.

Booking a sliding door repair in Sudbury
Repairs in Sudbury 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 Sudbury?
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
- Lock and gearbox replacement. A new mechanism when the handle turns but the door will not lock.
- 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.
Questions about sliding door repairs in Sudbury
Is there a call-out charge in Sudbury?
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.
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.
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.
Can a sliding door track be repaired?
A damaged sliding door track can often be repaired or refurbished, depending on the door and how badly the track is worn. On some systems a replacement track cover can be fitted over a worn track, and on others a damaged section can be repaired. If the track is part of a frame that is failing more widely, replacement may be the better option.
