Mold Removal & Remediation in Saint Paul, MN
Containment, HEPA filtration, and antimicrobial treatment remove mold colonies at the source and stop cross-contamination through the rest of the home. 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.
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
What does building on sandstone change?
It changes how concentrated water behaves. St. Peter sandstone is weakly cemented and erodes readily when flow is directed at it, so a downspout or a broken lateral discharging against the bluff face can undercut material rather than simply wetting it. Diffuse moisture is far less consequential than a concentrated stream.
Why do problems appear at snowmelt rather than during summer storms?
Because the winter prepares them. Deep frost widens joints and cracks over several months, and the melt then delivers a large volume of water into openings that were smaller before the freeze. Summer rain meets a wall that has not just spent a season being worked open.
The house is on a slope above the river. Does that help drainage?
For surface water yes, for the uphill wall no. Slope carries rain away from the downhill side but sends subsurface water toward whatever is cut into the hill. On bluff lots the uphill foundation wall is a retaining structure, and it is usually the one that shows moisture first.
