Blown mineral wool insulation for Walsall properties

Walsall sits in the West Midlands, around 8 miles north-west of Birmingham. We work across the WS1 district, including nearby Wednesbury, Aldridge and Willenhall.

Most Walsall 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. Walsall 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. The West Midlands 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 compliance, in Walsall filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Funding in England

In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.

When is it not the right choice?

Very narrow or uneven cavities, walls with lots of mortar snots and debris, and some very exposed elevations can be better suited to bonded bead, which flows around obstructions and is certified for a wider range of exposure zones in some systems. The survey says which and why.

The West Midlands has a mix of moderate and more exposed sites, so each wall is judged on its own. The survey records the exposure of each wall before recommending a material, or recommending against filling.
