Cavity wall insulation for Solihull properties
If your property is in Solihull or the B91 district or nearby Birmingham, Smethwick and Sutton Coldfield, it is within our West Midlands coverage. It is roughly 7 miles south-east of Birmingham.
Where a Solihull property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. Solihull 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.
In terms of approvals, in Solihull filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Is my wall suitable for cavity wall insulation?
Most homes built from the 1920s onwards have cavity walls, but having a cavity is not the same as being suitable. The Energy Saving Trust's rule of thumb is a cavity of at least 50mm, clear of rubble, behind masonry in good condition, on a wall that is not exposed to severe driving rain or flood risk.
