Damp investigation after cavity insulation in Newcastle upon Tyne

Damp investigation after cavity insulation in Newcastle upon Tyne is priced before you book, and what we find is written up with photos. 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 Newcastle upon Tyne properties

If your property is in Newcastle upon Tyne or the NE1 district or nearby Gateshead, Wallsend and Hebburn, it is within our Tyne and Wear coverage. Newcastle upon Tyne is one of the main towns we cover in Tyne and Wear.

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

Wind-driven rain is the first thing the surveyor weighs up. 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.

In terms of approvals, if cavity wall insulation follows in Newcastle upon Tyne, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
