Basement Water Intrusionhigh

Kansas City and St. Louis metro areas have heavy clay soils and older housing stock prone to basement seepage. Block wall foundations from the mid-20th century show lateral bowing, efflorescence, and active seepage at high rates.

Sinkhole Risk — Karst Geologymedium

Termitesmedium

Missouri is in a moderate-to-heavy termite zone. St. Louis and Kansas City both have active subterranean termite populations. Southern Missouri is in a higher-pressure zone given the warmer climate.

Older Electrical Systemsmedium

St. Louis city and county have large concentrations of pre-WWII brick homes. Outdated 60-amp service, knob-and-tube wiring, and fuse panels are common in this housing stock, creating insurance and fire safety concerns.
