Damp investigation after cavity insulation in Rochester

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

Damp investigation after cavity insulation for Rochester properties

Our Kent coverage takes in Rochester (ME1) and nearby Chatham, Strood and Gillingham. It is around 8 miles north of Maidstone.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Rochester properties, so you can choose who fixes them. We never cold-call in Rochester or anywhere else, and we do not work with doorstep claims companies.

Local weather affects which walls can be filled. Much of Kent 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.
