Damp investigation after cavity insulation in Maidenhead

Maidenhead homeowners, buyers, landlords and agents can book a damp investigation with the price agreed first. 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 for Maidenhead properties

Maidenhead is among the towns we cover in Berkshire, alongside Slough, Windsor and Bracknell. It is about 12 miles north-east of Reading.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Maidenhead properties, so you can choose who fixes them. Damp in an insulated Maidenhead home is not always the insulation's fault, so the diagnosis comes before any extraction.

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.

For regulations, if cavity wall insulation follows in Maidenhead, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
