Damp investigation after cavity insulation for Thatcham properties
If your property is in Thatcham or the RG19 district or nearby Newbury, Reading and Lower Earley, it is within our Berkshire coverage. It is roughly 13 miles west of Reading.
Damp in an insulated Thatcham home is not always the insulation's fault, so the diagnosis comes before any extraction. We never cold-call in Thatcham or anywhere else, and we do not work with doorstep claims companies.
Every elevation is judged on its own exposure. Much of Berkshire 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.
In terms of approvals, if cavity wall insulation follows in Thatcham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
