Repair or replace: sliding doors in Milton Keynes
Here is what usually goes wrong with sliding doors, and what can be done about it:
When sending photos of a Milton Keynes 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.
If a sliding door at your Milton Keynes home has started to drag, clean the bottom track thoroughly before booking anything, as grit alone can cause the problem.
- Repairing or refurbishing a damaged track removes the dips and burrs that make rollers jump, which stops a panel coming off its track.
- 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.

Questions about sliding door repairs in Milton Keynes
How quickly can you fix a sliding door in Milton Keynes?
We offer a repair date in the MK9 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.
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.
What photos should I send for a repair quote?
Send a photo of the whole door from inside, close-ups of the handle, the lock edge and the bottom track, and any label or marking on the frame or glass spacer. A short video of the door opening and closing is especially helpful. Tell us roughly how old the door is and what it is doing wrong.
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.
