I just completed having my house gutted from last years hurricanes which 
caused black mold. All affected sheetrock, studs,floors I had removed. I had 
the 
abaters use 20%hydrogen peroxide on rafters. I rented 4 ozone machines and ran 
them 2 days. I had the home hepa vacumed and a complete wipe down with TKO. 
All followup tests were negative with higher mold spores outside than in.Good 
Luck.
