Cavity insulation top-up for Newcastle under Lyme properties

Our Staffordshire coverage takes in Newcastle under Lyme (ST5) and nearby Stoke-on-Trent, Longton and Kidsgrove. It is about 2 miles west of Stoke-on-Trent.

Newcastle under Lyme properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it. A suitable wall in Newcastle under Lyme is usually filled in a single day from outside, with drill holes made good to match the pointing.

Exposure matters for every cavity wall. Staffordshire 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 compliance, in Newcastle under Lyme filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
