Cavity wall insulation removal for Crowthorne properties

We cover Crowthorne and the RG45 postcode district, including nearby Sandhurst, Wokingham and Bracknell. It is roughly 10 miles south-east of Reading.

Damp in an insulated Crowthorne home is not always the insulation's fault, so the diagnosis comes before any extraction. Where a Crowthorne 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.

Every elevation is judged on its own exposure. Much of Berkshire 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 Crowthorne, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

How extraction works

Bricks are carefully removed in a line near the base and at intervals higher up where needed. The fill is broken up and drawn out with an extraction vacuum, the cavity is cleared and checked with a camera, and the bricks are rebuilt in matching mortar. Extracted material is bagged and disposed of properly.
