Cavity wall insulation removal for Peterlee properties

If your property is in Peterlee or the SR8 district or nearby Seaham, Hartlepool and Durham, it is within our County Durham coverage. It is around 9 miles east of Durham.

Where a Peterlee 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. Damp in an insulated Peterlee home is not always the insulation's fault, so the diagnosis comes before any extraction.

Every elevation is judged on its own exposure. County Durham 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, if cavity wall insulation follows in Peterlee, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

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.
