I have spoken with some Environmental companies and they all said the same thing, "Why bother testing for mold? Decide if you want it cleaned up, but deal with the real problem of moisture." It's the same thing for us reporting on damage to the home from moisture. We don't mention that the structural damage "appears to be damage, suggest further testing". We tell people (depending on the situation) they have water leaking into the house causing damage to the structure.
I also remind my people that mold is everywhere. It's reported on the news along with pollen counts.
