Damp investigation after cavity insulation in Gloucester

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. In Gloucester the visit is priced up front, and any follow-on work is quoted separately so you can choose.

We never cold-call in Gloucester 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 Gloucester properties, so you can choose who fixes them.

Every elevation is judged on its own exposure. Gloucestershire 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.
