Cavity insulation for new builds and extensions for Wolverhampton properties
Our West Midlands coverage takes in Wolverhampton (WV1) and nearby Wednesfield, Willenhall and Tipton. It is around 12 miles north-west of Birmingham.
For semi-detached and terraced homes in Wolverhampton, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. If a wall in Wolverhampton 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.
Exposure matters for every cavity wall. 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.
In terms of approvals, in Wolverhampton 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.

Extensions that join an older house
Where an extension meets an existing cavity wall, the junction is a weak point. We can borescope and fill the existing wall at the same time so the old and new walls perform together.
