Cavity insulation for new builds and extensions for Kelso properties

If your property is in Kelso or the TD5 district or nearby Galashiels and Hawick, it is within our Scottish Borders coverage. It is about 16 miles east of Galashiels.

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

Local weather affects which walls can be filled. The Scottish Borders 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.

For regulations, in Kelso no building warrant is needed for insulation within a wall, but the work must meet the building standards.

Funding in Scotland

In Scotland, Home Energy Scotland is the route to the Home Energy Scotland Grant and Loan and Warmer Homes Scotland.

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.
