Existing insulation and guarantee check for Catford properties

Our Greater London coverage takes in Catford (SE6) and nearby Blackheath, Greenwich and Beckenham. It is about 6 miles south-east of London.

A survey in Catford gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Every inspection point in Catford is photographed and logged, so you have a record to show a buyer, lender or contractor.

Every elevation is judged on its own exposure. 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.

As for paperwork, if cavity wall insulation follows in Catford, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
