Black mold removal in Franklin means stopping the water, sealing off the area, removing colonized drywall, insulation and flooring, then cleaning and drying the framing before anything is rebuilt. EPA doesn't treat dark color as a sign of extra danger, and visible growth rarely needs a lab test. Call the number on this page to be connected with a local mold remediation company in Franklin.

What happens when you call
You'll reach an independent mold remediation company working in Franklin and the rest of Williamson County. They'll ask what you see and where, whether the house has taken on water, and whether the HVAC is involved. Expect a site visit with a moisture meter, an inspection of the crawl space or basement, and a written scope covering containment, removal, cleaning, drying and the final check. If you want clearance testing, Angi suggests hiring a separate company for it.
What affects the cost
Angi reports a national typical range of $1,223 to $3,758, with most pros charging $10 to $25 per square foot. Nationally, basement jobs run $500 to $3,000 and whole-house work $10,000 to $30,000. Middle Tennessee prices vary. Cost climbs with:
- The area affected, including inside walls and under floors.
- Finished basements and custom trim that must come out.
- Ductwork or air handler contamination.
- Containment across several rooms.
- The rebuild after removal.
Jobs of $25,000 or more need a Tennessee contractor's license with the S-F mold remediation classification. Williamson County isn't on TDCI's Home Improvement license list.

Local conditions in Franklin
Franklin, the Williamson County seat about 19 miles from Nashville, sits in the Harpeth River watershed, and the city calls the Harpeth and its tributaries its biggest flood risk, especially after heavy rain upstream. In May 2010 about 16.1 inches fell in two days; the Harpeth crested above its 1948 record and flooded downtown and subdivisions on all sides of town, and the fire department says hundreds of residents were displaced. The river reaches flood stage at 30 feet on the gauge near Pinkerton Park. The city takes part in the NFIP, provides flood zone determinations and keeps elevation certificates for many properties. Building and Neighborhood Services handles both floodplain management and building permits, and takes property maintenance complaints online or by phone.
Checklist before the visit
- Shut off the water feeding the problem.
- Photograph growth and water lines.
- Look up your flood zone if water came from outside.
- Keep the HVAC off if vents look affected.
- Leave the patch alone; don't sand or spray it.
