Cavity insulation for new builds and extensions for Long Eaton properties
Long Eaton sits in Derbyshire, roughly 9 miles east of Derby. We work across the NG10 district, including nearby Ilkeston, Heanor and Derby.
Most Long Eaton houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. Long Eaton properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.
Before any material is chosen, exposure is checked. Derbyshire 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.
In terms of approvals, in Long Eaton filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
