Cavity wall insulation removal for Blyth properties

Blyth sits in Northumberland. We work across the NE24 district, including nearby Ashington, Cramlington and Morpeth.

We never cold-call in Blyth or anywhere else, and we do not work with doorstep claims companies. Where a Blyth wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up.

Wind-driven rain is the first thing the surveyor weighs up. 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, if cavity wall insulation follows in Blyth, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

How extraction works

Bricks are carefully removed in a line near the base and at intervals higher up where needed. The fill is broken up and drawn out with an extraction vacuum, the cavity is cleared and checked with a camera, and the bricks are rebuilt in matching mortar. Extracted material is bagged and disposed of properly.
