What a licensed remediation job actually involves, in the order it happens. Every step below is the contractor's work, not ours.
-
Step 1: Assessment
A licensed assessor establishes whether there is growth, how far it extends, and where the moisture is coming from.
-
Step 2: Containment
Barriers and negative air pressure go up first, so disturbing material does not move spores into clean rooms.
-
Step 3: Removal
Porous material that cannot be cleaned comes out - drywall cut past the moisture line, insulation, carpet pad, cabinet bases.
-
Step 4: Drying
Dehumidifiers and air movers bring the structure back to a dry standard, with readings logged from the material rather than the surface.
What drives moisture problems in St. Charles
Our local pros take mold removal work across St. Charles, from the middle out to New Town. Frenchtown is the Missouri River's west-bank landing, and the 1993 flood still marks which blocks sit on the floodplain and which climbed the bluff toward New Town.
Housing stock
Only 43.6 percent of the housing here went up after 1989; the median construction year is 1986. A split stock: river-town brick and frame on full basements in Frenchtown, and post-1980 tract on the uplands, averaging a 1986 median with 56 percent predating 1990.
Climate and water risk
May alone accounts for 11.9 percent of the 45.71 inches this area sees in an average year, on 1991–2020 normals recorded 1.3 miles away at ST CHARLES ELM PT. May's 5.45 inches is a slow spring peak on a river that drains a third of the continent. Frenchtown takes that as groundwater the Missouri is holding against the landing; the bluff takes it as runoff down streets that were the original grade to the river.
Common moisture and mold problems in St. Charles
- Missouri River groundwater holding Frenchtown basements wet when the river is high, even behind the levee
- Bluff streets shedding May rain onto the next downhill foundation, the original path to the landing
- 1993-flood silt and fill in the lowest blocks, still settling and still wet
- River-town brick with rubble foundations and no damp-proof course on the landing

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.
