Damp investigation after cavity insulation for Cricklewood properties
Cricklewood sits in Greater London, around 5 miles north-west of London. We work across the NW2 district, including nearby Kilburn, Willesden and Chalk Farm.
If your Cricklewood installation has a guarantee, we check it first; the guarantee route may cover the work. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Cricklewood properties, so you can choose who fixes them.
Every elevation is judged on its own exposure. 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.
As for paperwork, if cavity wall insulation follows in Cricklewood, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
