Questions worth asking any installer
Who actually does the fitting?
Ask who will carry out the fitting and who to contact if anything needs attention afterwards. We will explain this before you decide.
Is the price fixed?
You will receive a written quote after the survey so you can review what is included before deciding.
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.
