Damp investigation after cavity insulation in Chester

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

Damp investigation after cavity insulation for Chester properties

We cover Chester and the CH1 postcode district, including nearby Ellesmere Port Town, Runcorn and Widnes. Chester is one of the main towns we cover in Cheshire.

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

Local weather affects which walls can be filled. Cheshire 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 Chester, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
