Damp investigation after cavity insulation in Peckham

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

Exposure matters for every cavity wall. Much of Greater London 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.
