Why moisture builds up in Holcomb homes

Water nearby: The St. Francis River and the Missouri-Arkansas state line pass just west of Holcomb.

Setting: Holcomb is in the western Missouri Bootheel, which the state's Bootheel article describes as a very flat floodplain between the Mississippi and St. Francis rivers.

Missouri summers are hot and humid. NOAA's 1991-2020 normals put average yearly precipitation at Springfield 44.7 inches, Poplar Bluff 50.8 inches. Warm, damp air is what lets mold take hold in attics, crawlspaces and bathrooms.

Questions

Common questions.

What river is near Holcomb?

The St. Francis River runs just west of the city, along with the Missouri-Arkansas state line.

Why is mold common in southern Missouri homes?

Southern Missouri has humid summers and about 45 to 50 inches of precipitation a year, based on NOAA normals for Springfield and West Plains. EPA advises keeping indoor humidity below 60 percent, ideally 30 to 50 percent. Basements, crawlspaces and bathrooms are where moisture tends to collect.

Why do crawlspaces and basements matter in Missouri houses?

EPA notes that crawl spaces with high humidity are common sites of hidden mold growth, especially over bare soil. Missouri summers are humid, so foundation moisture is a frequent buyer concern. EPA also advises grading the ground away from the foundation so it does not stay wet.
