150m² of failed foam, Winchester: extraction and ThermaBead refill
A large house with 150m² of cavity wall filled with failed foam insulation, plus loose rubble in the cavity. The rear extension was surveyed separately and left out — it did not need the work.
- 150m² of failed foam extracted
- Full rubble clearance
- ThermaBead bonded bead refill
- Extension surveyed and excluded — only quoted what was needed
What we did
We extracted all 150m² of foam, removed the loose rubble, and refilled the whole cavity with ThermaBead bonded beads. The rear extension was surveyed and excluded from the quote because the borescope showed it did not need treatment.
Why it matters
We only quoted for the walls that needed it. Leaving the extension out kept the cost down and kept the quote honest. A borescope survey before every job means we never recommend work that is not necessary.
Suspect failed foam in your walls?
We carry out borescope surveys before every job. If the foam has failed, we extract it and refill with a modern bonded bead system.
