Damp investigation after cavity insulation for Hornchurch properties
Our Greater London coverage takes in Hornchurch (RM12) and nearby Romford, Dagenham and Becontree. It is roughly 15 miles east of London.
Where a Hornchurch wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up. Damp in an insulated Hornchurch home is not always the insulation's fault, so the diagnosis comes before any extraction.
Before any material is chosen, exposure is checked. 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 Hornchurch, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
