Cavity wall extraction and ThermaBead replacement, Gosport
Failed 1990s polystyrene bead insulation extracted using our own Extract Vac machines. The walls were dried and inspected before being fully re-insulated with ThermaBead EPS bead. The customer reported a significant improvement in warmth within days.

The problem
The original polystyrene bead insulation had been in the cavity since the 1990s. Over time it had settled, clumped and in places broken down, leaving cold spots and allowing moisture to track across the cavity. A borescope survey confirmed the extent of the failure across all elevations.
What we did
We extracted the old bead insulation using our Extract Vac machines, which are designed specifically for this work. Once the cavity was clear, we dried and inspected the walls before refilling with ThermaBead EPS bonded bead — a modern system with a Kiwa and IAA certification that bonds in place and cannot settle or shift.
The result
The customer reported a significant improvement in warmth within days of the work being completed. The new ThermaBead system is TrustMark registered and comes with a full guarantee.
