Damp investigation after cavity insulation in Burnham-on-Sea

Damp investigation after cavity insulation in Burnham-on-Sea is priced before you book, and what we find is written up with photos.

Damp investigation after cavity insulation 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.

If your Burnham-on-Sea installation has a guarantee, we check it first; the guarantee route may cover the work. Damp in an insulated Burnham-on-Sea home is not always the insulation's fault, so the diagnosis comes before any extraction.

Before any material is chosen, exposure is checked. 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.

For regulations, if cavity wall insulation follows in Burnham-on-Sea, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
