Mold Removal & Remediation in Florissant, MO
Containment, HEPA filtration, and antimicrobial treatment eliminate mold colonies at the source and prevent cross-contamination throughout the property. Mold remediation removes affected porous materials and corrects the moisture source that allowed growth. The work is done under containment with HEPA filtration so spores are not carried into unaffected rooms, and the area is cleared only once the underlying moisture problem has been resolved.
Independent local pros · containment before removal
Remediation is the step after the assessment, not before it. A local pro establishes how far the growth extends and what is feeding it, because removing what is visible while the moisture source is still running puts the same colony back in the same wall. Texas and several other states also set a square-footage point above which the work has to be done by a licensed remediator — the service note below covers where that line falls in this city.

Frequently asked questions
The window well sits lower than the yard now. Was it built that way?
No, the yard rose around it. Decades of settling and added soil leave an original well below grade, so it collects surface water it was never meant to see. The house did not sink; the ground came up.
The Missouri is miles from this ranch. Why would it still matter?
It sets the outlet. When the big river is high, Coldwater Creek cannot dump, and a 1963 basement is the unused capacity. You do not need shoreline to feel the Missouri's stage. When the Missouri is high, Coldwater Creek cannot dump, and a 1963 basement in Ferguson-side streets is the overflow.
Window wells that now sit below the yard. How did that happen?
Thirty years of silt and yard fill. The well was at grade in 1963; the yard rose; May rain now pours in over the lip. The tile may still work. The well has become a funnel. Raise the lip or the yard, or May rain will keep using the well as a funnel no matter how clear the tile is.
