Asbestos on forced air ducting
(Zone 5, Des Moines, Iowa 1,100 sq ft, 1 story with dormer upstairs 1920’s built)
After deciding to finish our basement, I had a radon guy out to look at the house for mitigation since our 2 home tests were a little above the ‘4’ actionable level.
The guy was knowledgeable and looked around and pointed out that we have asbestos ‘paper’ wrapping the old part of our forced air ducts that we should paint over with an oil based paint to ‘contain’ it.
Which got us (wife and self) thinking…if we want to keep asbestos out of the air this is the absolutely worst place to have it, and by painting the outside we are not really addressing the real problem inside the ducts that are blowing this around the house. It’s my understanding that this was applied to seal any gaps in the sheet metal, so those gaps are now where the asbestos mineral is entering the airstream and it really needs to be removed altogether.
So I’ve called an asbestos removal company and am waiting to hear back from them. The only good thing is that it is not all of the ducting, however it is some of the hardest to reach ones, like the one running upstairs enclosed in a wall.
Needless to say we’re employing our electric space heaters until we can resolve this. But I find it funny that I searched and could not find anything related to this topic here, while this is definitely a green building topic as green means healthy air, water, building, etc.
Anyone else have experiences similar? I’d like to know how others have dealt with this appropriately.
