Mold air samples can help determine the extent of a mold problem and sometimes the presence of a mold problem. Too often homebuyers and homeowners are under the impression that mold air sampling is an inspection or assessment for the presence of mold in a home or structure.
Mold air sampling will not identify the source of the mold problem, and may not even indicate there is a mold problem. Some mold spores don’t generally become aerosolized / airborne unless they are disturbed or there is a drastic humidity change, some may not be airborne at certain times of day.
It should be understood by homebuyers that although hundreds of “mold tests” are sold each week by home inspectors and people involved in Real Estate; a mold inspection (assessment) is the only way to be sure “home does or does not have a mold problem”.
With an elevated mold air sampling report only, recommendation should be to have a mold inspection/assessment which will identify the source and location and extent of the problem, and provide written detailed remediation protocols. You cannot label a home as having a mold problem based solely on mold air samples alone.
Tip: request that home be in closed house conditions 12 hours prior to “inspection” sampling and that NO heavy cleaning or vacuuming is done during the 12 hours prior.
This may save us some work, seems every week someone calls with an elevated mold report from an HI and then we find there is no mold problem. We learn later that homeowner /maid vacuumed and cleaned prior to home inspection which probably caused elevated count.
