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 for Carlisle properties

If your property is in Carlisle or the CA3 district or nearby Penrith, Workington and Whitehaven, it is within our Cumbria coverage. Carlisle is one of the main towns we cover in Cumbria.

If your Carlisle installation has a guarantee, we check it first; the guarantee route may cover the work. We never cold-call in Carlisle or anywhere else, and we do not work with doorstep claims companies.

Before any material is chosen, exposure is checked. Parts of Cumbria 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.

For regulations, if cavity wall insulation follows in Carlisle, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
