Blown mineral wool insulation for Falmouth properties
We cover Falmouth and the TR11 postcode district, including nearby Truro, Redruth and Camborne. It is around 7 miles south of Truro.
A suitable wall in Falmouth is usually filled in a single day from outside, with drill holes made good to match the pointing. Falmouth properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.
Exposure matters for every cavity wall. Parts of Cornwall face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.
For regulations, in Falmouth 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.
