Saint Louis homeowners finding mold in their home need three things immediately: a complete picture of the scope, a clear binding price, and fast professional action. Koppers Waterproofing delivers all three — thermal imaging, air sampling, written estimate, and IICRC S520 protocol from the first inspection through final air clearance testing.
After inspection, you receive a complete written itemized estimate for your Saint Louis project. The process follows IICRC S520 from containment setup through antimicrobial surface treatment and post-clearance air testing.
We've worked in Saint Louis area restaurants, medical facilities, retail spaces, warehouses, and multi-unit residential buildings. HVAC-distributed mold is assessed on every Saint Louis commercial inspection as standard.

Not sure if your Saint Louis property has an actionable mold problem? Our inspection delivers documented answers — calibrated air sampling through certified labs, thermal imaging, moisture mapping, and surface swabs to build a complete picture before any remediation is recommended.
Pre-sale mold inspections in Saint Louis are among our most requested services — buyers, sellers, agents, and lenders need documented mold status before transactions close. Our reports meet both insurance submission and real estate disclosure requirements in Saint Louis, MI.
Toxigenic mold species — particularly Stachybotrys — appear in Saint Louis properties with histories of water damage or chronic moisture. They require full containment, PPE-equipped removal, and HEPA air scrubbing throughout the entire work period. Our Saint Louis black mold protocol starts with confirmed species identification through certified lab analysis — not a visual assumption.
After removal, every exposed surface in your Saint Louis property receives EPA-registered antimicrobial treatment specific to toxigenic species. The job closes with post-clearance air sampling and a written clearance report.
Remediation removes the active colony. Prevention keeps it from coming back — which in Saint Louis's humidity conditions requires addressing the moisture source directly. Every Koppers Waterproofing project in Saint Louis includes moisture source identification and documented prevention recommendations as standard deliverables.
Our optional maintenance program for Saint Louis customers includes 30-day and 90-day follow-up air quality checks — documenting that the property remains clear after remediation closes.

Called Koppers Waterproofing for a Saint Louis crawl space inspection after heavy rain flooding.
