Damp investigation after cavity insulation for Witham properties
Witham sits in Essex, roughly 9 miles north-east of Chelmsford. We work across the CM8 district, including nearby Maldon, Braintree and Chelmsford.
If your Witham installation has a guarantee, we check it first; the guarantee route may cover the work. We never cold-call in Witham or anywhere else, and we do not work with doorstep claims companies.
Exposure matters for every cavity wall. Much of Essex sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.
As for paperwork, if cavity wall insulation follows in Witham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England
Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.
