Reviews
Rated 4.9 by Florissant-area neighbors
Called about a musty smell and they walked me through every step before starting. The area was contained properly and the odor was gone when they finished.
Professional containment, HEPA vacuuming, the whole process was textbook. Worth hiring certified pros.

Local knowledge
Mold Testing for Florissant, MO homes
Mold Testing in Florissant tends to start the same way mold does across Saint Louis County: humid seasons that keep indoor moisture high for weeks at a time. When that moisture sits for even a day or two, mold takes hold, and that is when homeowners from Calverton Park, Berkeley, Hazelwood and the rest of Florissant call us.
We handle mold testing for Florissant the right way. We find and fix the moisture source first, because mold always returns if the water problem is left behind, then we contain the area and remove the mold safely.
Our team is based in Valley Park, about 30 minutes from our Valley Park base, so we can usually reach a Florissant home the same day. Our methods follow public guidance from the EPA and the CDC on handling indoor mold safely.

Do I need mold testing if I can already see mold?
If mold is visible with an obvious moisture source, testing usually isn't necessary before remediation. Testing is more useful for ambiguous cases or documentation needs.

Air samples measure spore concentration in the air, useful for smell without a visible source. Surface samples identify the species on a specific visible growth.

Will my insurance cover mold testing in Florissant?
It depends on the cause. When the mold follows a sudden, covered event, there is often coverage. We bill your carrier directly and document the loss so your Florissant claim moves.
