Common sliding door faults we fix in Seaham
Here is what usually goes wrong with sliding doors, and what can be done about it:
When sending photos of a Seaham 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.
Is the patio door in your Seaham house leaking at the bottom after heavy rain? Check the drainage slots in the outer frame are clear before assuming a seal has failed.
- Quoting from photos and a short video means many repairs can be priced without a visit, saving time and the diagnostic visit charge for straightforward jobs.
- 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.
- 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.

Booking a sliding door repair in Seaham
We repair sliding doors in Seaham and nearby Houghton-le-Spring and Sunderland. You approve the price first, then we book the visit; 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 Seaham?
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
- 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.
- Handle replacement. Replacing broken or loose handles, including key-lockable versions.
Questions about sliding door repairs in Seaham
Do you repair sliding doors in Seaham?
Yes. We repair sliding doors in Seaham and across County Durham, including nearby Houghton-le-Spring. Send photos or a short video and we will tell you the likely fix and cost before booking a visit.
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.
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.
