Testing & Assessment
Mold Inspection & Testing in Florissant, MO
An assessment establishes whether mold is present, where it is growing, and how far it extends — before anyone quotes removal. A mold inspection locates moisture and growth that a room-level look would miss, reading wall cavities, subfloor, and the areas behind finished surfaces. The result is a scope: what is affected, what has to come out, and what is driving the moisture.
Most people reach this page after noticing something rather than after something broke: a smell that returns, a stain that spreads, a room that feels damp. An inspection answers what is actually there and where the moisture comes from, which is the information every later decision depends on. Several states, Texas among them, keep assessment and remediation as separate licensed roles specifically so the party identifying the problem is not the party selling the fix. Nothing here is medical advice — if you have health questions, those are for a clinician.

Frequently asked questions
Jefferson City is also on the Missouri. Why is this terrace a different job?
The capital sits on a bluff cut into rock. Florissant sits on a silt terrace in St. Louis County, draining to Coldwater Creek. May rain here is a creek-and-water-table job, not a hillside seepage job on limestone. Old Town Florissant ranches sit on silt and a creek, not on a capital limestone cut, so a bluff-seepage script misses them.
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.
