Cavity insulation for new builds and extensions in Leominster

Leominster homeowners, landlords and managing agents can book cavity insulation for new builds and extensions with a free survey first. For new walls the cavity is insulated as it is built, using full-fill mineral wool batts or partial-fill boards fixed to the inner leaf.

Cavity insulation for new builds and extensions for Leominster properties

If your property is in Leominster or the HR6 district or nearby Hereford, Ledbury and Ross-on-Wye, it is within our Herefordshire coverage. It is around 12 miles north of Hereford.

A suitable wall in Leominster is usually filled in a single day from outside, with drill holes made good to match the pointing. Most Leominster 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.

Every elevation is judged on its own exposure. Herefordshire 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.

In terms of approvals, in Leominster 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.
