Missouri Hazard Risk Overview

Risk levels based on housing data, climate, and environmental history.

Seasonal humidity and older housing create mold growth risk, especially in basements and crawl spaces.

Environmental Hazards in Missouri

St. Louis has documented some of the highest childhood lead poisoning rates in the United States. The city's extensive stock of pre-1978 housing — including Victorian-era homes with original paint, trim, and woodwork — creates widespread lead paint exposure risk. Kansas City also has significant pre-1978 housing with lead paint. Lead dust testing is strongly recommended in any Missouri home built before 1978.

Missouri's location along the Missouri and Mississippi Rivers creates significant flood risk that translates directly to mold exposure. Tornado damage to homes can also expose hidden mold in wall cavities and attic spaces. Missouri's variable climate — hot, humid summers combined with cold winters — creates condensation and moisture conditions favorable to mold growth year-round.

Post-Storm Mold Testing

Missouri homeowners should test for mold after any flooding, tornado damage, or roof damage. After any significant water intrusion, mold can begin growing within 24-48 hours in Missouri's warm summers.
