Blown mineral wool insulation for Egham properties

If your property is in Egham or the TW20 district or nearby Staines, Sunbury-on-Thames and Walton-on-Thames, it is within our Surrey coverage. It is about 14 miles north of Guildford.

A suitable wall in Egham is usually filled in a single day from outside, with drill holes made good to match the pointing. Egham properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.

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.

On the rules side, in Egham filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Funding in England

In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.

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.
