Cavity insulation for new builds and extensions for Droitwich properties
If your property is in Droitwich or the WR9 district or nearby Bromsgrove, Worcester and Stourport-on-Severn, it is within our Worcestershire coverage. It is roughly 6 miles north-east of Worcester.
Most Droitwich 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. If a wall in Droitwich 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.
Every elevation is judged on its own exposure. Worcestershire 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 Droitwich filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
