Cavity insulation for new builds and extensions for Bedford properties
Our Bedfordshire coverage takes in Bedford (MK40) and nearby Ampthill, Leighton Buzzard and Dunstable. Bedford is one of the main towns we cover in Bedfordshire.
A suitable wall in Bedford is usually filled in a single day from outside, with drill holes made good to match the pointing. Most Bedford houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is.
Before any material is chosen, exposure is checked. Much of Bedfordshire 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, in Bedford filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

What we work from
Your architect's or designer's specification and the energy calculation for the job. We match the product, thickness and fixing to that spec, keep cavities clean as the walls rise, and fit cavity trays, closers and stop ends where shown so the building control inspection goes smoothly.
