Sometimes mold hides inside walls, under floors or in ductwork. Air sampling measures what's floating in the air you breathe and compares it to what's outside.
Mold air sampling uses a calibrated pump to draw a measured volume of air through a collection cassette, capturing airborne mold spores. The samples are sent to a laboratory, where spores are identified and counted. An outdoor control sample is collected at the same time for comparison.
When indoor spore levels are significantly higher than outdoors, or when the types of mold indoors differ from those outside, it can indicate a hidden mold source — even when nothing is visible.
Air sampling is especially helpful when there's a musty odor without visible growth, after water damage, when occupants have unexplained symptoms, or to help confirm conditions after remediation has been completed.
Air sampling answers questions that a visual inspection alone can't.
A musty smell with no visible mold to explain it.
Check air quality following leaks, flooding or plumbing failures.
Households with allergies, asthma or other health concerns.
Help confirm conditions after mold remediation work is finished.
It's natural to worry when a home smells musty or a family member's allergies flare indoors. Air sampling turns that worry into measurable information.
The comparison between indoor and outdoor samples is key. Some spores are always present outdoors, so the lab results are interpreted relative to the outdoor baseline rather than as a single number.
If results suggest a hidden source, Mark can combine air sampling with moisture readings and thermal imaging to help narrow down where the problem is coming from.
Each mold air sampling visit includes:
At minimum, one indoor sample from the area of concern plus one outdoor control sample. Larger homes or multiple problem areas may need additional samples. Mark will recommend the right number.
Keep windows and doors closed beforehand and avoid heavy cleaning, dusting or running air purifiers right before sampling, since these can skew results.
Not exactly. It shows whether airborne spores are elevated and which types are present. Locating the source usually requires a visual inspection and moisture investigation.
No, it's an add-on service. You can book it with your inspection or as a stand-alone visit.
A careful process for reliable lab results.
