Remove and refill for Gerrards Cross properties

Gerrards Cross sits in Buckinghamshire, roughly 33 miles south of Milton Keynes. We work across the SL9 district, including nearby Chalfont Saint Peter, Amersham and Chesham.

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

Why refill at all?

Often the original problem was the wrong material for the exposure, poor installation or defects in the outer wall, not cavity insulation as such. Once the defects are fixed and the cavity is clean, a suitable certified system can usually go back in. Where the wall is too exposed for any fill, we say so and leave it empty.
