Damp investigation after cavity insulation in Stratford

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

Damp investigation after cavity insulation for Stratford properties

If your property is in Stratford or the E15 district or nearby Bow, Canning Town and Canary Wharf, it is within our Greater London coverage. It is about 6 miles east of London.

Damp in an insulated Stratford home is not always the insulation's fault, so the diagnosis comes before any extraction. If your Stratford installation has a guarantee, we check it first; the guarantee route may cover the work.

Local weather affects which walls can be filled. 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.

On compliance, if cavity wall insulation follows in Stratford, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
