Damp investigation after cavity insulation in Stockport

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 Stockport and the wider SK1 postcode district, and the price is confirmed before anyone visits.

Damp investigation after cavity insulation for Stockport properties

If your property is in Stockport or the SK1 district or nearby Hazel Grove, Cheadle Hulme and Denton, it is within our Greater Manchester coverage. It is roughly 6 miles south-east of Manchester.

Damp in an insulated Stockport home is not always the insulation's fault, so the diagnosis comes before any extraction. Where a Stockport 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.

Every elevation is judged on its own exposure. 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.

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

Rules in England

Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

Defective pointing, cracked render and porous bricks letting rain in; leaking gutters and downpipes; fill bridging the cavity where mortar droppings or debris have collected; ground levels above the damp-proof course; and condensation from cooking, drying clothes and too little ventilation.
