A door is the first thing people touch when they visit your home, so it needs to look right and feel solid. We only fit doors we would put on our own house, and we fit them ourselves — properly packed, properly sealed and properly adjusted so they close with one finger in January as well as July.

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.
