Damp investigation after cavity insulation in Salisbury

Damp investigation after cavity insulation in Salisbury 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 Salisbury properties

Our Wiltshire coverage takes in Salisbury (SP1) and nearby Trowbridge, Chippenham and Swindon. It is roughly 34 miles south of Swindon.

We never cold-call in Salisbury or anywhere else, and we do not work with doorstep claims companies. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Salisbury properties, so you can choose who fixes them.

Exposure matters for every cavity wall. Wiltshire 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, if cavity wall insulation follows in Salisbury, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
