A bay is a structural window — it often carries load from above. Done wrong you get cracked plaster and sticking sashes. We support the opening correctly before anything comes out.

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?
