Stepping up on my soap box!
As a home inspector, you would be a fool to get into Mold testing. The average home inspector would make more money if they concentrated doing home inspections and not anciallry mold testing. Most of the mold testing folks are newer home inspectors who are trying to be everything to everyone. They are trying to make as much money as possible without doing the hard work of building a home inspection business.
I don't blame the inspectors, I blame the labs that promote it as the magic cure for a home inspection business that is suffering from the lack of business. Our friends at Pro-Lab lead the way along with NACHI. They are the largest promoters of mold testing for home inspectors.
Home inspectors need to be finding the source of moisture in the home that is supporting the fungal growth. Knowing what type of mold does not do a whole lot of good, if you don't know what is sustaining it. Mold in a home is not good, it really does not matter what type it is. Yes, some impact the health of some individuals more than others.
I treat mold this way: If you see mold you have mold; If you smell mold you have mold; you then need to locate the source of moisture that is supporting it; then you need to report on the problem and that it needs ___ repairs. Then I tell my clients that the mold needs to be properly cleaned. They need to visit the
U.S. Environmental Protection Agency for the proper guidelines or hire a professional abatement contractor if it is more than they can handle.
I'm not scared of reporting that I found mold a X location in a house and that it is being caused by the leaking ____ or whatever. Repair the ___ clean up the mold and go on with life.
I have been doing it this way since the mid 1990's and have never had a problem.
Stepping off of my soap box.
