Damp investigation after cavity insulation in Worthing

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