Blown mineral wool insulation for Woking properties
We cover Woking and the GU22 postcode district, including nearby Guildford, Egham and Walton-on-Thames. It is around 6 miles north of Guildford.
For semi-detached and terraced homes in Woking, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. Where a Woking property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.
Every elevation is judged on its own exposure. 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.
As for paperwork, in Woking filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Why choose mineral wool?
Mineral wool fibres are treated to shed water, so moisture that gets into the outer leaf runs down the cavity rather than tracking across. It is classed as non-combustible, which matters for some flats and taller buildings, and it is usually the lower-cost certified option.
