Damp investigation after cavity insulation in Weston-super-Mare

Damp investigation after cavity insulation in Weston-super-Mare is priced before you book, and what we find is written up with photos. A damp investigation finds out why an insulated wall is showing damp or mould: rain getting in through defects, bridged or wet fill, debris in the cavity, a breached damp-proof course, or condensation.

Damp investigation after cavity insulation for Weston-super-Mare properties

We cover Weston-super-Mare and the BS23 postcode district, including nearby Burnham-on-Sea, Clevedon and Nailsea. It is roughly 24 miles north of Taunton.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Weston-super-Mare properties, so you can choose who fixes them. Where a Weston-super-Mare wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up.

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.

On compliance, if cavity wall insulation follows in Weston-super-Mare, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England
