Brick slip EWI in Waltham Abbey: questions
How much should I budget for brick slip external wall insulation in Waltham Abbey?
Budget around £185–£265 per square metre of wall for the system and finish, plus scaffolding priced per house. The survey measures your walls in Waltham Abbey and fixes the total in writing.
Is building control approval needed for brick slip external wall insulation in Waltham Abbey?
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.
How long will the work take in Waltham Abbey?
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.
