Damp investigation after cavity insulation in Craigavon

For properties in Craigavon, a damp investigation starts with a clear price and ends with a written record of what was found and done. 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 Craigavon properties

If your property is in Craigavon or the BT65 district or nearby Lurgan, Portadown and Armagh, it is within our County Armagh coverage. Craigavon is one of the main towns we cover in County Armagh.

Where a Craigavon wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up. If your Craigavon installation has a guarantee, we check it first; the guarantee route may cover the work.

Local weather affects which walls can be filled. 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 Craigavon, inserting cavity wall insulation needs a building control application to the council before work starts.
