Cavity insulation for new builds and extensions for Scarborough properties
Our North Yorkshire coverage takes in Scarborough (YO12) and nearby Redcar, York and Middlesbrough. It is about 35 miles north-east of York.
A suitable wall in Scarborough is usually filled in a single day from outside, with drill holes made good to match the pointing. For semi-detached and terraced homes in Scarborough, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side.
Every elevation is judged on its own exposure. North Yorkshire has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
On the rules side, in Scarborough filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

Extensions that join an older house
Where an extension meets an existing cavity wall, the junction is a weak point. We can borescope and fill the existing wall at the same time so the old and new walls perform together.
