Blown mineral wool insulation for St Neots properties
St Neots is among the towns we cover in Cambridgeshire, alongside Huntingdon, Cambridge and Peterborough. It is around 16 miles west of Cambridge.
A suitable wall in St Neots is usually filled in a single day from outside, with drill holes made good to match the pointing. St Neots properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it.
Before any material is chosen, exposure is checked. Much of Cambridgeshire 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 compliance, in St Neots filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

When is it not the right choice?
Very narrow or uneven cavities, walls with lots of mortar snots and debris, and some very exposed elevations can be better suited to bonded bead, which flows around obstructions and is certified for a wider range of exposure zones in some systems. The survey says which and why.
