Damp investigation after cavity insulation in Ashton-under-Lyne

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. We cover Ashton-under-Lyne and the wider OL7 postcode district, and the price is confirmed before anyone visits.

Damp investigation after cavity insulation for Ashton-under-Lyne properties

If your property is in Ashton-under-Lyne or the OL7 district or nearby Dukinfield, Stalybridge and Droylsden, it is within our Greater Manchester coverage. It is roughly 6 miles east of Manchester.

We never cold-call in Ashton-under-Lyne or anywhere else, and we do not work with doorstep claims companies. Where an Ashton-under-Lyne 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.

Before any material is chosen, exposure is checked. Greater Manchester 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 Ashton-under-Lyne, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
