Cavity wall insulation for Bridgwater properties
If your property is in Bridgwater or the TA6 district or nearby Burnham-on-Sea, Taunton and Weston-super-Mare, it is within our Somerset coverage. It is about 9 miles north-east of Taunton.
A suitable wall in Bridgwater is usually filled in a single day from outside, with drill holes made good to match the pointing. If a wall in Bridgwater 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 Bridgwater 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.
