We could smell something musty in the hallway closet but never found anything. Turned out to be a slow leak behind the wall from an old pipe. They found it in under an hour and the smell was gone once the work was done.

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.

Good to know
Mold Odor Removal in Florissant, MO: common questions
Can there be mold if I can't see any?
Yes. Mold often grows inside wall cavities, under flooring, or in ductwork long before it becomes visible on a surface. A persistent musty smell is one of the most common signs of hidden growth.
How do you find odor without visible mold?
We walk the space to locate where the smell is strongest, then use a moisture meter to check nearby walls, floors, and baseboards. If needed, we open a small access point to confirm what's happening inside a cavity.
Is a musty smell in my basement normal for Missouri homes?
A faint concrete smell can be normal, but a strong, persistent musty odor usually isn't. It's worth having checked, especially in basements near foundations that see spring runoff.
Is the mold odor removal 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 air fresheners or ozone machines fix the smell?
They can mask odor temporarily but don't address the source. If mold or trapped moisture is causing the smell, it will typically return once the treatment wears off.
What if you can't find a source?
It happens occasionally, especially with faint or intermittent smells. We'll tell you honestly if we don't find active moisture or mold rather than recommending unnecessary removal.
Will my insurance cover mold odor removal 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.
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.
