Cavity wall insulation removal for Welling properties

Welling sits in Greater London, around 11 miles east of London. We work across the DA16 district, including nearby Bexley, Eltham and Thamesmead.

Where a Welling 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 Welling home is not always the insulation's fault, so the diagnosis comes before any extraction.

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.

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

Rules in England

Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

If you have a guarantee

Contact your original installer first. If that does not resolve it within two months, CIGA's process applies for CIGA-guaranteed installs. Removing insulation yourself can void a guarantee, so speak to the provider before work.
