Cavity insulation for new builds and extensions for Ross-on-Wye properties

Our Herefordshire coverage takes in Ross-on-Wye (HR9) and nearby Ledbury, Hereford and Leominster. It is about 12 miles south-east of Hereford.

For semi-detached and terraced homes in Ross-on-Wye, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. Most Ross-on-Wye 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.

Wind-driven rain is the first thing the surveyor weighs up. 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.

As for paperwork, in Ross-on-Wye filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
