Damp investigation after cavity insulation in Basildon

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

Damp investigation after cavity insulation for Basildon properties

Our Essex coverage takes in Basildon (SS16) and nearby Stanford-le-Hope, Wickford and Billericay. It is around 12 miles south of Chelmsford.

Damp in an insulated Basildon home is not always the insulation's fault, so the diagnosis comes before any extraction. Where a Basildon 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.

Local weather affects which walls can be filled. Much of Essex 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 Basildon, 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.
