Cavity insulation for new builds and extensions for Nottingham properties
We cover Nottingham and the NG1 postcode district, including nearby West Bridgford, Arnold and Hucknall. Nottingham is one of the main towns we cover in Nottinghamshire.
Where a Nottingham property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. For semi-detached and terraced homes in Nottingham, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.
Local weather affects which walls can be filled. Much of Nottinghamshire 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.
As for paperwork, in Nottingham 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.
