Soaked furnace wrap cleaned up after a basement flood
Example project

- Home
- 1940s house in Kent with an unfinished basement
- Original request
- Dry out and restore the basement after a failed sump pump let the water rise to the furnace
- Testing
- A fallen piece of soggy wrap from the floor and a sample of the furnace jacket
- Found
- Asbestos in the wrap and in the jacket
- Material
- The furnace jacket and the soaked wrap on the three lowest duct arms, about 60 sq ft in all
- Agency notice
- Filed, since 60 sq ft is over the 48 sq ft mark
- Timeline
- Filing, then two days of work; the drying company and heating contractor follow
- Cost
- $5,600
Scope of work
Plastic around the furnace and under the wet duct arms, the fallen pieces misted and bagged first, the soaked wrap and jacket taken off wet, the old furnace cut free and bagged, the sound upper wrap left, disposal, a HEPA clean and an air test. Drying, the replacement furnace and any insurance paperwork are separate.
Project overview
In this example, a sump pump fails in the basement of a 1940s house in Kent and the water rises to the furnace and the lowest duct arms. Their white wrap is soaked, sagging and coming off in pieces on the floor. The drying company stops and asks for a test of a fallen piece and of the furnace jacket, and both are positive.
The fallen pieces are misted and bagged first. The soaked wrap on the three lowest arms and the jacket come off wet, about 60 sq ft in all, so the notice goes to Puget Sound Clean Air Agency. The wrap higher up is dry and sound, so it stays with its cut ends sealed, and the drying company and the heating contractor can then start.
The goal
The goal is a basement ready for drying and a new furnace, with the soaked wrap and the old jacket gone and the dry wrap sealed.
Process
- Same day Water pumped out, fans kept off the wet wrap, samples taken.
- Before work Results come back; the filing goes in with the insurer’s file number noted.
- Day one Plastic up, fallen pieces bagged, soaked wrap and jacket taken off wet.
- Day two The old furnace cut free, cut ends sealed, HEPA clean and an air test.
Planning right
- Keep fans and dehumidifiers pointed away from wet wrap until it is tested.
- Do not sweep or shop-vac the fallen pieces.
- Ask the insurer whether testing and removal belong to the water claim.
- Write down where dry wrap remains, for the next time work is done in the basement.
