Cavity insulation top-up in Ashington

Cavity insulation top-up for Ashington properties

Our Northumberland coverage takes in Ashington (NE63) and nearby Blyth, Morpeth and Cramlington. It is around 4 miles north-west of Blyth.

If a wall in Ashington is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason. A suitable wall in Ashington is usually filled in a single day from outside, with drill holes made good to match the pointing.

Before any material is chosen, exposure is checked. Northumberland 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 Ashington filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

When a top-up is not enough

If the existing fill is wet, contaminated with debris or breaking down, adding more on top can make things worse. In that case we tell you the honest option, which may be partial or full removal and refill.
