Mold remediation in Franklin means fixing the water problem, building containment around the moldy area, removing damaged porous materials and drying the structure before rebuild. EPA recommends a professional for areas larger than about 10 square feet. 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 remediation company that works in Franklin. Explain where the mold is, how big it looks, and what caused the water: a supply line, a roof, a sump pump failure or river flooding. If the house is in a flood zone, say so; it may affect insurance and rebuild rules.
At the site visit, the company should measure moisture, check lower levels, crawl spaces and attics, and explain what will be removed and what can be cleaned. Ask for the scope, containment plan and how drying will be confirmed in writing.
What drives the cost
- Area. Angi's national data puts most jobs at $1,223 to $3,758, about $10 to $25 per square foot.
- Finished space. Finished basements and bonus rooms mean more drywall, flooring and trim to remove; walls alone run $1,000 to $20,000 nationally.
- Containment. Larger jobs need negative air and more sheeting.
- Rebuild. Often quoted separately.
Middle Tennessee prices vary. Williamson County isn't on TDCI's list of counties requiring the Home Improvement license for smaller jobs, but projects of $25,000 or more need a Tennessee contractor's license with S-F as the mold remediation classification.

Local conditions in Franklin
The city says the Harpeth River and its tributaries are Franklin's biggest flood risk, and heavy rain upstream affects the city. On May 1-2, 2010, about 16.1 inches of rain fell, the Harpeth crested above its 1948 record, and water reached downtown and subdivisions on all sides of town, with businesses along Hillsboro Road among the hardest hit. The Franklin Fire Department says hundreds of residents were displaced. The river reaches flood stage at 30 feet on the gauge near Pinkerton Park.
Franklin offers free flood zone determinations and keeps elevation certificates for many properties. Building and Neighborhood Services issues building permits, runs floodplain management, and enforces property maintenance codes, so renters with an unfixed leak can report it there too. In a Special Flood Hazard Area, ask about rebuild rules before you start.
Before the company arrives
- Stop the water or shut the main.
- Photograph everything and note dates.
- Call your insurer if a sudden leak caused it.
- Keep sensitive family members out of the area.
- Look up your flood zone with the city if the water came from outside.
