Repair or replace: sliding doors in Blandford Forum
Here is what usually goes wrong with sliding doors, and what can be done about it:
Is the patio door in your Blandford Forum house leaking at the bottom after heavy rain? Check the drainage slots in the outer frame are clear before assuming a seal has failed.
Landlords with properties in Blandford Forum can often keep a sound sliding door working with a roller and lock service rather than a full replacement.
- 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.
- 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.
- 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.

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.
What we can repair
- Adjustment and service. Re-aligning panels, cleaning tracks and checking seals and drainage.
- Lock and gearbox replacement. A new mechanism when the handle turns but the door will not lock.
- Roller replacement. New rollers for each sliding panel, restoring a smooth, quiet action.
Questions about sliding door repairs in Blandford Forum
Is there a call-out charge in Blandford Forum?
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 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.
Why won't my sliding door lock?
A sliding door that will not lock usually has a failed lock gearbox, a worn or broken keep, or a panel that has dropped so the hooks no longer line up with the frame. Forcing the handle can make it worse. Photos of the handle, the lock edge and the frame where the hooks engage usually show which part has failed.
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.
