Cavity insulation for new builds and extensions for Stretford properties

We cover Stretford and the M32 postcode district, including nearby Urmston, Sale and Salford. It is about 4 miles south-west of Manchester.

A suitable wall in Stretford is usually filled in a single day from outside, with drill holes made good to match the pointing. Stretford properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.

Local weather affects which walls can be filled. 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.

In terms of approvals, in Stretford filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
