Basement mold in Franklin often follows Harpeth River or creek flooding, seepage after heavy rain, or humid air condensing on cool foundation walls. Removal means stopping the water, removing moldy drywall, carpet and insulation, and cleaning and drying the framing and concrete. Call the number on this page to be connected with a local mold remediation company in Franklin.

What happens when you call
You'll be connected with an independent mold remediation company that works in Franklin. Expect a few quick questions: how big the affected area looks, whether the basement is finished, whether water came in from outside or from a plumbing line, and when it happened. The company then arranges a visit to measure moisture, look for the water source and write up a scope. A good scope spells out containment, what will be removed and disposed of, how framing and concrete will be cleaned, how drying will be confirmed, and whether rebuilding is included.
Cost
The national ranges Angi reports are about $500 to $3,000 for basement mold remediation and $2,250 to $7,100 for foundation sealing. Middle Tennessee prices vary. The main factors:
- Area affected and how high on the walls growth reaches
- Finished surfaces, trim and flooring to be removed
- Whether a furnace or ductwork in the basement is involved
- Waterproofing or drainage work
- A follow-up check by an independent inspector
Projects of $25,000 or more need a Tennessee contractor's license, and mold remediation is the S-F classification. Angi recommends using separate companies for testing and remediation.

Franklin conditions
Franklin is the Williamson County seat, about 19 miles from Nashville, and the city calls the Harpeth River and its tributaries its biggest flood risk. Franklin sits in the Harpeth watershed and feels heavy rain that falls upstream. In May 2010 about 16.1 inches fell in two days; the Harpeth crested above its 1948 record, flooding downtown and subdivisions on all sides of town, and hundreds of residents were displaced. The river reaches flood stage at 30 feet at the gauge near Pinkerton Park. Franklin takes part in the National Flood Insurance Program, provides flood zone determinations at no charge, and keeps elevation certificates for many properties, all through Building and Neighborhood Services, which also issues building permits. A standard homeowners policy does not cover flooding.
Checklist before the company arrives
- Ask Building and Neighborhood Services for your flood zone if you don't know it
- Photograph the damage and any water lines
- Don't run the furnace or AC if the basement air handler may have mold, per EPA
- Remove valuables from the work area
- Find your homeowners and flood policies
