Damp investigation after cavity insulation in Heswall

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

Damp investigation after cavity insulation for Heswall properties

Heswall sits in Merseyside, about 7 miles south-west of Liverpool. We work across the CH60 district, including nearby Bebington, Birkenhead and Wallasey.

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

Local weather affects which walls can be filled. Merseyside 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.

As for paperwork, if cavity wall insulation follows in Heswall, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
