Damp investigation after cavity insulation in Fleet

For properties in Fleet, 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 Fleet properties

Our Hampshire coverage takes in Fleet (GU51) and nearby Farnborough, Aldershot and Yateley. It is about 36 miles north-east of Southampton.

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

Exposure matters for every cavity wall. Hampshire has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

On compliance, if cavity wall insulation follows in Fleet, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
