We just bought a home in the North-East and were told by the home inspector that we had some mold growth in the attic, but that he didn't think it was the "toxic" black kind so it wasn't urgent, but we should get it checked out at some point. We got a 2nd opinion who agreed and in fact said some people just live with it.
We had a mold test done to confirm and my understanding is that it concurred with what the home inspector said. It was mold, but not the worst kind.
Main House Air Test:
Aspergillus penicillium = 14 raw - 560 count / m3
Cladosporium = 5 raw - 200 count / m3
Ascospores = 6 raw - 240 count / m3
Attic Sheathing Bio-Tape:
Cladosporium: "Very Heavy"
He estimated it would cost $3,000 to remediate.
We then passed his remediation plan onto local mold remediation companies who quoted us $5,000 - $8,000! And that is just for the mold, does not include installation of an attic fan to prevent future growth or new insulation.
I want to be responsible with our health and the health of our house, but this feels like a crazy amount of money for a relatively low amount of everyday mold.
Is it irresponsible to do nothing?
