As an inspector I do about 4 to 5 Air samples and several swab samples dailey. The sampling with lab reports company findings and moisture test goes for $275.00 for two samples, more depending on the Sqft of the home. for a total of $1,375 per day. I carry E&O and liability that covers my home inspections and my fungal testing also; I do several fungal inspections a week for insurance companies. I like doing the fungal inspections that is why I have spent my money and time on all the training. Now you are right if you have an inspector that does not know what he or she is doing or saying on the topic of fungal growths you could loose more than your pride! It seems like you are not in favor of the testing; some times the home inspector has to think outside the box.
