Damp investigation after cavity insulation in Waterlooville

For properties in Waterlooville, 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 Waterlooville properties

Waterlooville sits in Hampshire, around 16 miles east of Southampton. We work across the PO7 district, including nearby Havant, Portsmouth and Fareham.

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

Local weather affects which walls can be filled. 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.

For regulations, if cavity wall insulation follows in Waterlooville, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
