Cavity wall insulation removal for Sunbury-on-Thames properties

If your property is in Sunbury-on-Thames or the TW16 district or nearby Walton-on-Thames, Esher and Staines, it is within our Surrey coverage. It is about 14 miles north-east of Guildford.

Where a Sunbury-on-Thames 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 Sunbury-on-Thames home is not always the insulation's fault, so the diagnosis comes before any extraction.

Exposure matters for every cavity wall. Much of Surrey 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 Sunbury-on-Thames, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
