Cavity insulation for new builds and extensions for Burnham-on-Sea properties
Our Somerset coverage takes in Burnham-on-Sea (TA8) and nearby Weston-super-Mare, Bridgwater and Clevedon. It is around 16 miles north of Taunton.
Most Burnham-on-Sea 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 Burnham-on-Sea 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.
Wind-driven rain is the first thing the surveyor weighs up. Somerset 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 the rules side, in Burnham-on-Sea 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.
