Damp investigation after cavity insulation in Manchester

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 Manchester and the wider M2 postcode district, and the price is confirmed before anyone visits.

Damp investigation after cavity insulation for Manchester properties

We cover Manchester and the M2 postcode district, including nearby Salford, Failsworth and Droylsden. Manchester is one of the main towns we cover in Greater Manchester.

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

Local weather affects which walls can be filled. 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.

In terms of approvals, if cavity wall insulation follows in Manchester, 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.

Common causes we check

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.
