Inspector Fry Recommends Ten Mold Inspection Steps Before Buying a Home or
“To avoid buying a residence or commercial building that has significant,
hidden toxic mold growth inside walls, ceilings, floors, attic, basement,
crawl space, and heating/cooling equipment and ducts, buyers should have
the house, condo, or building thoroughly inspected and tested by a
Certified Mold Inspector, Certified Environmental Hygienist, or Professional
Industrial Hygienist,” suggests mold consultant Phillip Fry, webmaster since
www.moldinspector.com and author of five mold advice books.
The top ten mold inspection steps that need to be taken to protect a real
estate buyer are explained in detail at
www.buildingmoldinspection.com and include:
1. A careful physical, visual inspection of the roof, attic, all interior
rooms, garage, basement, crawl space, and the heating/cooling system to find
evidence of building defects, maintenance problems, water intrusion, water
damage, and mold growth. Such a thorough inspection will take at least one
to two hours or more to be thorough and complete.
2. During the physical inspection, the mold inspector or environmental
hygienist should use a professional moisture meter to scan the entire
surface of basement walls and the walls and floors of rooms containing
plumbing such as the kitchen, bathrooms, and laundry room.
3. All furniture and appliances should be inspected for water damage and
mold growth on all surfaces, including the backside and bottom.
4. All drapery, rugs, and carpeting need to be carefully inspected for water
damage and mold growth. The inspector should do at least one carpeting mold
test to submit for mold lab analysis.
5. The relative humidity of each room and area of the house (including the
attic, basement, crawl space, and garage) should be checked with a
hygrometer and recorded in the inspector’s notes. If the relative humidity
in a room or area exceeds 70% some or all of the time, such high humidity
alone is sufficient to drive big-time mold growth.
6. The insides of each heating, ventilating, and air conditioning (HVAC) air
supply duct should be carefully inspected for accumulated dirt and mold
7. The outward air flow from at least one HVAC air supply should be mold
tested (while the system is running on fan ventilation) for five minutes
with an air pump and Air-O-Cell or other appropriate testing media, with a
pump air flow rate of 15 cubic liters per minute, for a total air sampling
of 75 cubic liters (5 minutes multiplied by 15 cubic liters per minute).
This HVAC air sample will then be sent to an accredited mold lab for mold
species identification and quantification. If a residence or building has
more than one HVAC system, test at least one air supply duct register in
each separate system. If a building has a serious mold problem, there is
often the presence of elevated levels of airborne mold spores in the HVAC
system, which often itself is a location and source for toxic mold growth.
8. The room air in each of at least three important rooms (such as living
room and bedrooms) should be mold tested in the same way previously
explained for testing HVAC outward air flow.
9. If there is any visible mold growth, an actual physical (“bulk”) sample
of that mold growth should be collected for mold lab analysis or mold growth
colonies should be taken from the moldy areas with such techniques as Scotch
tape lift sampling, sterile swabs, and microscopic slide surface sampling.
10. Surface sampling mold tests should be done to collect landed/deposited
mold spores for lab analysis from out of the way places such as the top side
of ceiling fans, top side of kitchen cabinets, and the top side of door and
window trim that are rarely cleaned. Surface sampling often gives a more
realistic insight into the degree of mold infestation than air sampling. The
inspector should do both surface sampling and air testing for comprehensive
