Damp investigation after cavity insulation in Coventry

Coventry homeowners, buyers, landlords and agents can book a damp investigation with the price agreed first. 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 Coventry properties

Our West Midlands coverage takes in Coventry (CV1) and nearby Solihull, Sutton Coldfield and Birmingham. It is about 17 miles east of Birmingham.

If your Coventry installation has a guarantee, we check it first; the guarantee route may cover the work. Damp in an insulated Coventry home is not always the insulation's fault, so the diagnosis comes before any extraction.

Before any material is chosen, exposure is checked. The West Midlands 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 Coventry, 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.
