MoldHelpUSAWhy mold is common in Chattanooga
Lovell Field averages about 55 inches of precipitation a year under NOAA's 1991–2020 normals, and the winter months are among the wettest, with December through March each near or above 5 inches. The valley holds humid air in summer, so a damp crawl space or basement rarely dries without help.
About 55% of Chattanooga's homes were built before 1980, according to the Census Bureau, and many older neighborhoods sit on slopes. In St. Elmo, Highland Park, and on the North Shore, houses on hillsides take water against the uphill foundation wall after long rains, and crawl spaces under early 20th-century homes collect it. Newer homes in Hixson and East Brainerd bring attic air handlers and tight construction.
Getting wet materials dry within a day or two, as the EPA advises, keeps most of these from turning into remediation.

Tennessee mold licensing: what to check
Hamilton County is on Tennessee's Home Improvement license list, so Chattanooga residential jobs from $3,000 up to $25,000 need that license, and larger jobs need a state contractor license with the board's Mold Remediation specialty. Look it up in the Department of Commerce and Insurance search before signing. On a hillside lot, the scope should cover how water will be kept away from the foundation. See the Tennessee page.
Will insurance cover it?
Seepage through a hillside basement wall in Chattanooga is usually treated as gradual damage and excluded, which is why drainage matters more than the claim. A burst pipe or a storm-damaged roof is more likely to be covered, usually up to a mold limit. Water rising from the Tennessee River or South Chickamauga Creek is flood damage that needs a flood policy. The Tennessee Department of Commerce and Insurance hears complaints.
