Cavity insulation for new builds and extensions for Ellesmere Port Town properties

Ellesmere Port Town sits in Cheshire, roughly 6 miles north of Chester. We work across the CH65 district, including nearby Chester, Runcorn and Widnes.

A suitable wall in Ellesmere Port Town is usually filled in a single day from outside, with drill holes made good to match the pointing. Most Ellesmere Port Town 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.

Before any material is chosen, exposure is checked. Cheshire 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.

For regulations, in Ellesmere Port Town filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
