Damp investigation after cavity insulation for Penzance properties
Penzance sits in Cornwall, about 24 miles south-west of Truro. We work across the TR18 district, including nearby Camborne, Redruth and Falmouth.
If your Penzance installation has a guarantee, we check it first; the guarantee route may cover the work. We never cold-call in Penzance or anywhere else, and we do not work with doorstep claims companies.
Every elevation is judged on its own exposure. Parts of Cornwall 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.
As for paperwork, if cavity wall insulation follows in Penzance, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England
