Damp investigation after cavity insulation in Tonbridge

For properties in Tonbridge, a damp investigation starts with a clear price and ends with a written record of what was found and done. 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 Tonbridge properties

Tonbridge sits in Kent, around 12 miles south-west of Maidstone. We work across the TN9 district, including nearby Tunbridge Wells, Sevenoaks and Maidstone.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Tonbridge properties, so you can choose who fixes them. We never cold-call in Tonbridge or anywhere else, and we do not work with doorstep claims companies.

Every elevation is judged on its own exposure. Much of Kent 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 Tonbridge, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
