A street-by-street programme, Winchester: 13 homes in one month
A run of homes with failed cavity wall insulation and poor lofts. Survey notes on one property showed rubble on every lintel, debris two to three brick courses high along several elevations, and no mechanical extract ventilation in the kitchen or bathroom. Thirteen completed jobs in September 2025.
- 13 homes completed in one month
- Full rubble clearance before refill
- ThermaBead bonded bead refill
- Lofts upgraded to 400mm
- Ventilation issues flagged and reported
What the surveys found
Rubble on every lintel. Rubble two to three brick courses high along several elevations. Debris dumped back into the cavity by people replacing spalled bricks. No mechanical extract ventilation in the kitchen or bathroom. The same pattern repeated across the street.
What we did
Across 13 completed jobs we extracted the failed cavity insulation, including full rubble clearance where the borescope showed it was needed, and refilled with ThermaBead bonded beads. In the loft, we stripped out the old insulation and fitted 400mm of new insulation, eaves vent trays, a 150mm Celotex-insulated loft hatch and draught proofing. We also flagged the missing ventilation to the client — insulation and airflow have to be thought about together.
Why it matters
A programme like this shows we can survey, quote and deliver many homes at once without cutting corners on the bit nobody sees — the borescope survey and rubble clearance that make the new insulation actually work.
Running a programme of homes?
We can survey, quote and deliver multiple properties at once. We work with main contractors and local authorities across Hampshire and the south of England.
