Extensive green and white mold found on the underside of the first floor, the sub floor. This is caused by the chronic, long-term basement water flooding condition at this house. Not only is the ambient humidity high, the wicking of the water up the main beam support columns has caused the columns to be in jeopardy of failure and need to be replaced at great expense. The basement water issue needs to be resolved to prevent re-occurrence and the mold remediated. The owner wasn’t too happy.
