We only test — we don't sell abatement, remediation, or removal work of any kind. A lot of "free" or discounted testing comes from companies who profit from finding a problem for them to fix. Since we have no abatement business on the other side, our results are just the results — an honest, unbiased answer instead of a sales pitch.
Serving homeowners in Falmouth and the surrounding Cape Cod area with independent mold air quality testing — a musty smell, a past leak, or just wanting a clear answer are all common reasons to test. Coastal humidity, older shingle-style homes, and homes that sit closed up for stretches of the year all make air quality testing a common request on the Cape.
A quick, non-invasive visit — usually well under an hour — measures indoor air in the room or area of concern and compares it against an outdoor baseline. Lab results are typically back within 24 to 48 hours.
Same rate everywhere in Massachusetts — a base visit fee plus a per-sample lab cost, no regional markup for Falmouth specifically.
| Scope | Typical Total |
|---|---|
| 1 area + outdoor baseline (2 samples) | $620 |
| 2 areas + outdoor baseline (3 samples) | $705 |
| 3 areas + outdoor baseline (4 samples) | $790 |
| 4 areas + outdoor baseline (5 samples) | $875 |

Mold air sampling pulls a measured volume of air through a small cassette in a specific room or area, then compares the spore count and types in a lab against an outdoor baseline sample taken at the same time. That comparison is what actually shows whether indoor mold levels are elevated — some mold spores in outdoor air is completely normal, so testing indoor air alone wouldn't tell you much on its own.
Air sampling tests the air itself, and is the right call when there's a musty smell or general air-quality concern but nothing visibly growing on a surface. Bulk sampling collects a physical piece of an affected material — drywall, insulation, subfloor — to identify what's growing on something you can already see. Swab sampling is a quick swab taken directly from a stained or suspicious surface to confirm whether it's actually mold. It's common to need more than one type in the same visit.
The most common reasons are a musty smell with no visible source, recent water damage or a past leak (even one that's already been fixed), ongoing allergy-like symptoms that seem tied to being in the house, or wanting a clear answer before buying a home. None of these prove mold is present on their own — that's exactly what the test is for.
Most mold air sampling runs between $700 and $900, depending on how many areas of the home are tested and whether an outdoor baseline sample is included. Pricing breaks down into a base visit fee plus a per-sample lab cost, similar to how asbestos testing is priced.
It's a common step for buyers, especially with a finished basement or any history of water issues — a pre-purchase air test gives you a clear, lab-backed answer before you're committed, rather than finding out about a musty smell after closing.
Yes. "Free" or heavily discounted mold testing is often offered by companies that also sell mold remediation — which creates a financial incentive to find a problem for them to fix. An inspector who only tests, and doesn't also perform remediation, has no reason to tell you anything other than what the lab results actually show.
The site visit itself is usually quick — collecting an air sample per area plus an outdoor baseline typically takes well under an hour. Lab results are normally back within 24 to 48 hours, faster with rush turnaround.
