Damp investigation after cavity insulation in Exmouth

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

Damp investigation after cavity insulation for Exmouth properties

Our Devon coverage takes in Exmouth (EX8) and nearby Exeter, Newton Abbot and Torquay. It is about 9 miles south-east of Exeter.

If your Exmouth installation has a guarantee, we check it first; the guarantee route may cover the work. Damp in an insulated Exmouth home is not always the insulation's fault, so the diagnosis comes before any extraction.

Before any material is chosen, exposure is checked. Parts of Devon face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

For regulations, if cavity wall insulation follows in Exmouth, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
