The same window fitted two different ways will perform completely differently — on heat loss, on draughts and on how long it lasts. We survey, order and fit every job ourselves, so nothing gets lost between a salesman and a fitting team. If your existing frames are sound and it's only the glass that has failed, we'll tell you that too and replace the pane instead of selling you a full window.

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.
