Damp investigation after cavity insulation in Bootle

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. In Bootle the visit is priced up front, and any follow-on work is quoted separately so you can choose.

Damp investigation after cavity insulation for Bootle properties

If your property is in Bootle or the L21 district or nearby Wallasey, Liverpool and Maghull, it is within our Merseyside coverage. It is about 4 miles north of Liverpool.

Where a Bootle 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 Bootle home is not always the insulation's fault, so the diagnosis comes before any extraction.

Every elevation is judged on its own exposure. Merseyside 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.

As for paperwork, if cavity wall insulation follows in Bootle, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England
