Damp investigation after cavity insulation in Ballymena

For properties in Ballymena, 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 Ballymena properties

Ballymena sits in County Antrim, about 23 miles north-west of Belfast. We work across the BT42 district, including nearby Antrim, Larne and Newtownabbey.

If your Ballymena installation has a guarantee, we check it first; the guarantee route may cover the work. Damp in an insulated Ballymena home is not always the insulation's fault, so the diagnosis comes before any extraction.

Before any material is chosen, exposure is checked. Parts of County Antrim 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.

On the rules side, if cavity wall insulation follows in Ballymena, inserting cavity wall insulation needs a building control application to the council before work starts.
