Damp investigation after cavity insulation in Wallsend

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

Damp investigation after cavity insulation for Wallsend properties

If your property is in Wallsend or the NE28 district or nearby Hebburn, Jarrow and Gateshead, it is within our Tyne and Wear coverage. It is about 3 miles east of Newcastle upon Tyne.

We never cold-call in Wallsend or anywhere else, and we do not work with doorstep claims companies. Where a Wallsend 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.

Local weather affects which walls can be filled. Tyne and Wear 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 the rules side, if cavity wall insulation follows in Wallsend, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
