Damp investigation after cavity insulation in Derbyshire

For homes, landlords and businesses in Derbyshire, a damp investigation comes with a clear price and a plain-English record. 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 across Derbyshire

We cover 12 towns in Derbyshire, including Derby, Chesterfield, Long Eaton, Ilkeston, Swadlincote and more.

Every elevation is judged on its own exposure. Derbyshire 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.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Derbyshire properties, so you can choose who fixes them. Damp in an insulated Derbyshire home is not always the insulation's fault, so the diagnosis comes before any extraction.

Building Regulations in England

Filling an existing cavity wall is notifiable building work in England. Either a building notice goes to building control before the work, or the installer self-certifies it through a government-approved competent person scheme such as CIGA's CWISC scheme. The insulation used must also be suitable for the wall it goes into, which is why the survey checks construction, condition and exposure first.
