How mold
testing works.What it measures, and when you need it.

Inspection comes first

A good test starts with a good walkthrough. We inspect the home, check the places mold hides, the crawlspace, attic, around plumbing, behind problem walls, and look for moisture, staining, and the source. Often the inspection alone tells us what we need to know. Testing adds proof and finds what the eye cannot.

What air sampling measures

Air sampling captures the spores floating in your indoor air and compares them to an outdoor baseline. Every home has some mold spores, that is normal. The question is whether the indoor level is elevated, which signals a hidden source actively releasing spores. This is how we catch mold growing inside walls, under floors, or in ductwork where you cannot see it.

Surface and clearance testing

Surface sampling lifts a sample from a suspicious spot to confirm what it is. Clearance testing happens after remediation, it verifies the work actually brought the levels back to normal, so you have proof in writing rather than just our word. That matters for real estate and for your own peace of mind.

When you actually need a test

Test when you are buying or selling a home, when you smell or feel a problem you cannot locate, after a flood or major leak, or after remediation to confirm it worked. If you can already see the mold and you are going to remove it anyway, a test before the work is often optional. We will tell you honestly which situation you are in.
