Common sliding door faults we fix in Gosport
Before you replace a sliding door, it is worth knowing which faults can be put right:
When sending photos of a Gosport 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 an older sliding door in Gosport has several faults at once, such as misted glass, worn rollers and a failing lock, compare the total repair cost with a replacement before deciding.
- 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.
- 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.

From photos to fixed door in Gosport
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 PO12 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.
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
- 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 Gosport
Do you repair sliding doors in Gosport?
Yes. We repair sliding doors in Gosport and across Hampshire, including nearby Portsmouth. Send photos or a short video and we will tell you the likely fix and cost before booking a visit.
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.
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.
