Blown mineral wool insulation for Ruislip properties

Ruislip sits in Greater London, about 14 miles west of London. We work across the HA4 district, including nearby Northolt, Uxbridge and Harrow.

For semi-detached and terraced homes in Ruislip, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. A suitable wall in Ruislip is usually filled in a single day from outside, with drill holes made good to match the pointing.

Every elevation is judged on its own exposure. Much of Greater London 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 Ruislip 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.

Sources: GOV.UK: extending the ECO4 end date, government response; GOV.UK: Warm Homes Plan.

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.

What is included in Ruislip

  • Cavity barriers where needed
  • Making good to the mortar colour
