Bi-folds live or die on the fitting. If the opening isn't dead level and the track isn't set properly, the doors bind within a year. We take the time to get the structural opening right first, then fit and adjust each leaf individually.

Questions worth asking any installer
Who actually does the fitting?
We do. You deal with Martyn from the first phone call to the final clean-up — no subcontractors, no call centre.
Is the price fixed?
Yes. The price we quote after the survey is the price you pay. No day-of-fitting extras.
How much mess is there?
We use dust sheets, work room by room and clear up as we go. We wouldn't leave someone's home any different from our own.
Do I always need a full new window?
No. If it's just a misted or failed unit, we replace the pane and leave the frame — a fraction of the cost.
How far do you travel?
We're based in Cumbernauld and cover Glasgow, Falkirk, Stirling, Lanarkshire and the wider Central Scotland area.
