I have worked with industrial hygienist and certified mold inspectors from Hawaii to the East Coast. The ones listed below I trust will be honest and discuss the ins and outs of testing for Molds and bacteria commonly associated with water intrusion and damage to homes, apartments, and buildings.
Please note that I said Molds and Bacteria. Certain species of molds are grow on different types of building and household materials, e.g. Cry wall vs flooring tile. In addition, Gram negative and positive bacteria and their toxins are also present. The bacteria need to be cultured and identified.
