Damp investigation after cavity insulation in Reading

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

Damp investigation after cavity insulation for Reading properties

If your property is in Reading or the RG1 district or nearby Lower Earley, Wokingham and Crowthorne, it is within our Berkshire coverage. Reading is one of the main towns we cover in Berkshire.

Damp in an insulated Reading home is not always the insulation's fault, so the diagnosis comes before any extraction. We never cold-call in Reading or anywhere else, and we do not work with doorstep claims companies.

Wind-driven rain is the first thing the surveyor weighs up. 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.

On compliance, if cavity wall insulation follows in Reading, 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.
