Damp investigation after cavity insulation in Flint

Flint homeowners, buyers, landlords and agents can book a damp investigation with the price agreed first. 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 Flint properties

If your property is in Flint or the CH6 district or nearby Deeside, Buckley and Hawarden, it is within our Clwyd coverage. It is roughly 15 miles north-west of Wrexham.

Where a Flint 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. Damp in an insulated Flint 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 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.

As for paperwork, if cavity wall insulation follows in Flint, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.
