Mold Removal & Remediation in Ballwin, 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.
Quoted on site by the contractor who visits
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.

Category 3 black-water losses are handled with full PPE, biohazard disposal, and professional disinfection to restore safe conditions.
Frequently asked questions
The walkout side is dry. The uphill wall is wet every May. How is that one house?
The house is a dam in a hill. The walkout is the downhill face, open and drainable. The uphill wall is buried in a cut that intercepts May flow from the rest of the lot. Chert residuum here sheds along that cut rather than soaking in. You are seeing two climates on one foundation. Fix the high side's grade and downspouts before you treat the walkout as the problem.
Would a French drain on the downhill side help?
It would drain a side that is already the dry one. May is loading the uphill cut. A drain belongs on that high side, with an outlet that does not loop back into the same slope. Putting effort into the walkout patio because that is where you live misses the wall that is actually in the hill. The wet month is coming from above the house, not from the view.
The house is almost fifty years old. Is the coating just done?
On a slope this wet in May, original coatings fail first at the buried face, where backfill never dries. Fifty years is a full life for that film. Replacing it without changing the cut's drainage repeats the same failure. A drain and a fall away from the uphill wall are what give a new coating a chance. Age is the schedule; the hill is the reason.
