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.
No more allergy symptoms since they cleaned the mold from our HVAC and bedroom walls.
Our process
Our black mold removal process in Florissant, MO
Assess
We look at color, texture, and location, and take moisture readings before assuming anything about species.
Sample
If you want species confirmation, we coordinate a swab or air sample sent to an independent lab.
Contain
Full sheeting and negative air pressure isolate the work zone so spores don't travel to bedrooms or living areas.
Remove
Affected material is bagged and removed under HEPA filtration, with technicians in full PPE the entire time.
Confirm
We recheck moisture and surfaces before opening the containment, so you're not left wondering if it's really gone.

Good to know
Black Mold Removal in Florissant, MO: common questions
Is all black mold toxic?
No. Color alone doesn't tell you the species, and several common household molds appear dark or black without being the toxin-producing type people worry about. Regardless of species, mold growth should still be removed and the moisture source fixed.
Can black mold make my family sick?
Some people are more sensitive to mold exposure than others and may notice allergy-like symptoms, coughing, or irritation. If anyone in your household has respiratory issues, mention it when you call so we can adjust containment.
Will you find every spot of black mold in my house?
We inspect the areas you're concerned about plus common trouble spots like sink cabinets, window frames, and basement corners. If we suspect hidden growth behind a wall, we'll walk you through the options before opening anything up.
Is the black mold 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.
Do I need to test before removal?
Testing is optional for most homeowners. Visible mold on a porous surface gets removed either way. Testing is more useful for documentation, real estate transactions, or when someone in the home has ongoing health concerns.
How fast does black mold spread?
Given a steady moisture source, colonies can expand within days to weeks. That's why we focus on both removing what's there and identifying why it started growing in the first place.
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.
