Cavity wall insulation removal for Belper properties
Belper is among the towns we cover in Derbyshire, alongside Ripley, Heanor and Alfreton. It is around 7 miles north of Derby.
If your Belper installation has a guarantee, we check it first; the guarantee route may cover the work. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Belper properties, so you can choose who fixes them.
Before any material is chosen, exposure is checked. Derbyshire 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 Belper, 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.
