Damp investigation after cavity insulation in Ammanford

For properties in Ammanford, 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.
