Sliding door repairs in Porthcawl: what to know
Here is what usually goes wrong with sliding doors, and what can be done about it:
Where an older sliding door in Porthcawl 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.
If a sliding door at your Porthcawl home has started to drag, clean the bottom track thoroughly before booking anything, as grit alone can cause the problem.
- Adjusting a dropped or misaligned panel can cure draughts, rattles and a door that will not close fully against its seals.
- 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.
- Misted sealed units can usually be replaced individually with new safety glass units, restoring the view and the insulation of that panel.

Questions about sliding door repairs in Porthcawl
How quickly can you fix a sliding door in Porthcawl?
We offer a repair date in the CF36 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.
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.
