Cavity insulation for new builds and extensions for Ashton in Makerfield properties
Ashton in Makerfield sits in Greater Manchester, about 17 miles west of Manchester. We work across the WN4 district, including nearby Wigan, Leigh and Westhoughton.
If a wall in Ashton in Makerfield is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason. A suitable wall in Ashton in Makerfield is usually filled in a single day from outside, with drill holes made good to match the pointing.
Wind-driven rain is the first thing the surveyor weighs up. Greater Manchester has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
On the rules side, in Ashton in Makerfield filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
