Damp investigation after cavity insulation in Hawarden

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. We cover Hawarden and the wider CH5 postcode district, and the price is confirmed before anyone visits.

Damp investigation after cavity insulation for Hawarden properties

Hawarden sits in Clwyd, roughly 10 miles north of Wrexham. We work across the CH5 district, including nearby Deeside, Buckley and Flint.

Damp in an insulated Hawarden home is not always the insulation's fault, so the diagnosis comes before any extraction. Where a Hawarden 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.

Wind-driven rain is the first thing the surveyor weighs up. Parts of Clwyd 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 Hawarden, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.
