Damp investigation after cavity insulation in Dumfries and Galloway

Damp investigation after cavity insulation across Dumfries and Galloway, priced before you book, with the findings written up and photographed. 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.

Damp investigation after cavity insulation across Dumfries and Galloway

We cover 4 towns in Dumfries and Galloway: Dumfries, Stranraer, Annan and Castle Douglas.

Wind-driven rain is the first thing the surveyor weighs up. Parts of Dumfries and Galloway 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.

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

Building standards in Scotland

In Scotland, work associated with thermal insulating material within a wall is listed in schedule 3 of the Building (Scotland) Regulations as work that does not need a building warrant. It must still meet the building standards, so the survey still checks that the wall and the chosen material are suitable, including exposure to wind-driven rain.

Sources: Scottish Government: building work not requiring a warrant (schedule 3).
