Cavity insulation for new builds and extensions for Elgin properties

We cover Elgin and the IV30 postcode district, including nearby Inverurie.

Where an Elgin property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed. Most Elgin houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is.

Before any material is chosen, exposure is checked. Aberdeen and Grampian 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 Elgin no building warrant is needed for insulation within a wall, but the work must meet the building standards.

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.
