Damp investigation after cavity insulation in Berkshire

For homes, landlords and businesses in Berkshire, a damp investigation comes with a clear price and a plain-English record. 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 across Berkshire

We cover 11 towns in Berkshire, including Reading, Slough, Bracknell, Maidenhead, Wokingham and more.

Every elevation is judged on its own exposure. Much of Berkshire sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.

If your Berkshire installation has a guarantee, we check it first; the guarantee route may cover the work. Where a Berkshire 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.

Building Regulations in England

Filling an existing cavity wall is notifiable building work in England. Either a building notice goes to building control before the work, or the installer self-certifies it through a government-approved competent person scheme such as CIGA's CWISC scheme. The insulation used must also be suitable for the wall it goes into, which is why the survey checks construction, condition and exposure first.

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.
