Damp investigation after cavity insulation for Norwich properties
Norwich is among the towns we cover in Norfolk, alongside Great Yarmouth, Thetford and King's Lynn. Norwich is one of the main towns we cover in Norfolk.
Damp in an insulated Norwich home is not always the insulation's fault, so the diagnosis comes before any extraction. We never cold-call in Norwich or anywhere else, and we do not work with doorstep claims companies.
Before any material is chosen, exposure is checked. Much of Norfolk 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.
For regulations, if cavity wall insulation follows in Norwich, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
