Cavity insulation for new builds and extensions in Stirling

Cavity insulation for new builds and extensions for Stirling properties

Our Forth Valley coverage takes in Stirling (FK7) and nearby Alloa, Falkirk and Grangemouth. It is about 10 miles north-west of Falkirk.

A suitable wall in Stirling is usually filled in a single day from outside, with drill holes made good to match the pointing. If a wall in Stirling is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason.

Exposure matters for every cavity wall. The Forth Valley 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.

As for paperwork, in Stirling no building warrant is needed for insulation within a wall, but the work must meet the building standards.
