Tenants who hire a mold assessor often have no way to judge the quality of the work. At the October 2026 Safe Housing Collaborative conference, a panel of experienced assessors described what separates a full inspection from a quick visit. Their advice can help you know what to look for when you hire someone to test your home.
The panel described assessment as ninety percent of the job and sampling as only ten percent. A thorough assessor may spend five or six hours on site and often finds the mold without needing many samples. By contrast, a visit that consists of two quick air samples and a short report rarely answers the questions that matter. One panelist begins by asking occupants where in the home they feel worst and where they feel best.
Panelists agreed that no single credential guarantees a thorough inspection. Even in states that license assessors, they said, many inspectors take a couple of samples and leave. Experience, a background in restoration, and additional certifications from screening organizations count for more than a license alone. Asking how the assessor plans to search for the water source tells you more than a list of initials.
The panel stressed that a laboratory should report counts, not conclusions. Some laboratories label results as normal without knowing anything about the home. Interpretation belongs to the assessor who walked the building. Results reported only as low, medium, or high, without actual numbers, are difficult to use later. Panelists also cautioned against extrapolated reports, which can inflate numbers.
An infrared camera measures surface temperature, not moisture. Wet materials often read cooler, but air leaks and missing insulation produce similar cool spots, so every infrared finding needs confirmation with a moisture meter. Strong reports pair infrared images with ordinary photographs and map moisture readings on a floor plan, following the water damage standard known as IICRC S500.
