Why mold is common in Franklin
The NOAA station in Franklin averages about 54 inches of precipitation a year under the 1991–2020 normals, with May and December the wettest months. The Harpeth River winds through the city, and low ground near it takes water in heavy rain.
Franklin's housing is mostly new: about 54% of homes were built in 2000 or later, and only about 13% before 1980, according to the Census Bureau. In subdivisions such as Westhaven, Fieldstone Farms, and Berry Farms, mold usually traces to large homes with attic air handlers, finished bonus rooms over garages, and tight construction that holds shower and cooking moisture. The smaller stock of historic homes near downtown brings crawl spaces, plaster, and old plumbing.
The EPA's guidance is the same for both: materials that stay wet for more than a day or two are where mold starts.

| Lab sample, per sample (national) | $50–$350 |
| Typical remediation job (national) | $1,100–$3,400 |
We use national figures from Angi and HomeGuide for Franklin because no local survey meets our standard. Larger homes with bonus rooms and multiple air handlers often mean more square footage to inspect, and historic homes need care around original materials. See the remediation cost guide.
Tennessee mold licensing: what to check
Williamson County is not on Tennessee's Home Improvement license list, so in Franklin a state license is required only for jobs of $25,000 or more, where the contractor board's Mold Remediation specialty applies. For smaller jobs, check insurance, training, and references, and ask whether the City of Franklin requires a permit for the rebuild. Exterior work in the historic district may need design review. See the Tennessee page.
Will insurance cover it?
Franklin homeowners near the Harpeth should know that rising river water is flood damage, covered only by a flood policy. Inside the house, a sudden plumbing failure or AC overflow is more likely to be covered by a homeowners policy, usually up to a mold limit, while a slow leak or humid crawl space is commonly excluded. Take pictures before cleanup and call the insurer early. Franklin homeowners who cannot resolve a claim can contact the state Department of Commerce and Insurance. See does insurance cover mold.
