We had a musty smell in the hallway for months with nothing visible anywhere. The team used a camera to check inside the wall and found mold from an old leak we didn't even know about. Glad we finally had it checked.

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.
Post-remediation air quality test passed on the first try. Very happy with their work.

Local knowledge
Hidden Mold Remediation for Florissant, MO homes
Hidden Mold Remediation in Florissant tends to start the same way mold does across Saint Louis County: crawl spaces and sump pumps around Florissant that struggle to keep up during wet spells. 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 hidden mold remediation 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.

Good to know
Hidden Mold Remediation in Florissant, MO: common questions
I smell mold but can't see any. What should I do?
A persistent musty smell with no visible source is worth having inspected. We use moisture meters and cameras to locate hidden mold without unnecessary demolition.
Can hidden mold make a home smell musty without being visible?
Yes, mold growing inside a wall cavity, under flooring, or behind a cabinet can produce a noticeable smell well before it becomes visible on a surface.
Is hidden mold more dangerous than visible mold?
It isn't inherently more dangerous, but it often goes untreated longer since nobody knows it's there, which can let it spread further before it's addressed.
Is the hidden mold remediation you do in Florissant to a real standard?
Yes. Our crew follows the IICRC S520 standard for mold remediation, the same framework insurers and inspectors recognize across Saint Louis County.
Will you have to cut open my walls?
Sometimes a small opening is needed to confirm and access hidden mold, but we always try to locate it first with non-invasive tools to keep the opening as small as possible.
How do I know if past water damage left mold behind?
If an area was wet in the past and the smell or discoloration returned later, it's a strong indicator that moisture remained trapped inside a cavity.
Do I need to leave my Florissant home during the work?
Usually no. We seal the work area under negative air, so most of the Florissant home stays livable. For larger jobs we will tell you if it is better to step out for a day.
Do you serve Florissant?
Yes. We cover all of Florissant, including Calverton Park, Berkeley, Hazelwood, and the rest of the Florissant area. We are based in Valley Park, about 30 minutes from our Valley Park base, and answer our own phone around the clock.
