Cavity insulation top-up in Wallsend

Cavity insulation top-up for Wallsend properties

If your property is in Wallsend or the NE28 district or nearby Hebburn, Jarrow and Gateshead, it is within our Tyne and Wear coverage. It is roughly 3 miles east of Newcastle upon Tyne.

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

On the rules side, in Wallsend filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Funding in England

How do I know if my walls need a top-up?

Cold patches on internal walls, a thermal image showing uneven heat loss, or an EPC that says 'filled cavity' when parts of the house feel colder are all signs. Extensions are a common cause: the new wall is insulated as built, but the old wall it joins may have been left partly empty.
