Cavity wall insulation removal across the Isle of Wight
We cover 3 towns in the Isle of Wight: Ryde, Cowes and Sandown.
Before any material is chosen, exposure is checked. The Isle of Wight 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.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Isle of Wight properties, so you can choose who fixes them. Where an Isle of Wight 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.
Building Regulations in England
Filling an existing cavity wall is notifiable building work in England. Either a building notice goes to building control before the work, or the installer self-certifies it through a government-approved competent person scheme such as CIGA's CWISC scheme. The insulation used must also be suitable for the wall it goes into, which is why the survey checks construction, condition and exposure first.

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.
What is included
- Damp investigation and borescope diagnosis first
- Brick removal and reinstatement
