Brick slip EWI in Chesham: questions
Is building control approval needed for brick slip external wall insulation in Chesham?
Insulating more than half of a wall, or more than a quarter of the whole building envelope, counts as renovating a thermal element under the Building Regulations, so the wall should reach 0.30 W/m²K where that is technically, functionally and economically feasible, and building control must be involved. We arrange it as part of the job.
Do you cover Amersham as well as Chesham?
Yes. From Chesham we also cover Amersham, Berkhamsted and Chalfont St Peter, and the rest of Buckinghamshire.
How long will the work take in Chesham?
Two to six weeks on site for most houses, depending on size: bungalows are quicker, detached houses longer, weather allowing. Render isn't applied in rain or frost.
