Damp investigation after cavity insulation in Portadown

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

Damp investigation after cavity insulation for Portadown properties

We cover Portadown and the BT62 postcode district, including nearby Craigavon, Lurgan and Armagh. It is about 3 miles south-west of Craigavon.

We never cold-call in Portadown or anywhere else, and we do not work with doorstep claims companies. Damp in an insulated Portadown home is not always the insulation's fault, so the diagnosis comes before any extraction.

Every elevation is judged on its own exposure. Parts of County Armagh face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

In terms of approvals, if cavity wall insulation follows in Portadown, inserting cavity wall insulation needs a building control application to the council before work starts.
