Testing & Assessment
Mold Inspection & Testing in St. Charles, 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
The Missouri is behind a levee. Why is Frenchtown still the wet side of town?
A levee stops overbank flow. It does not stop groundwater. The landing is river alluvium, and a high Missouri holds that table against Frenchtown cellars whether or not the wall is overtopped. 1993 was the overbank story. Ordinary May is the seepage story.
New Town is up on the prairie. Is the river still involved?
Not as flood and not as groundwater. New Town's water is May rain on clay and whatever the next street sheds. Frenchtown's water is the Missouri. They share a city and a wettest month. They do not share a mechanism, and a repair that worked on the bluff will not read on the landing.
The cellar has silt in the corners years after 1993. Related?
That silt is the flood's calling card, and it is also a wick. Fine river sediment packed against a rubble wall holds moisture long after the crest. Cleaning it off the floor is not the same as getting it out of the joints. The 1993 water is gone. The 1993 dirt is still working.
