Damp investigation after cavity insulation in Hadley Wood

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. In Hadley Wood the visit is priced up front, and any follow-on work is quoted separately so you can choose.

Damp investigation after cavity insulation for Hadley Wood properties

Hadley Wood sits in Greater London, about 11 miles north of London. We work across the EN4 district, including nearby Barnet, Enfield Town and Finchley.

Where a Hadley Wood 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. We never cold-call in Hadley Wood or anywhere else, and we do not work with doorstep claims companies.

Local weather affects which walls can be filled. Much of Greater London 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.

On compliance, if cavity wall insulation follows in Hadley Wood, 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.
