Franklin's biggest flood risk is the Harpeth River and its tributaries, and in May 2010 the river crested above its 1948 record and flooded downtown and subdivisions on all sides of town. Crawl space mold here follows that kind of high water and, more often, the slow buildup of summer humidity under the floor. 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. They'll want to know what you've noticed, whether the crawl space has held water, and roughly how big the house is. On site, expect a full crawl of the space with moisture readings on the wood, a check of the ground barrier, insulation, ducts and plumbing, and a walk around the outside to see where roof and yard water go. The written estimate should explain the water source in plain terms, list what will be removed, and say how the space will be kept dry.
Cost factors
Angi reports national typical ranges of about $500 to $2,000 for crawl space mold remediation and $1,500 to $15,000 for encapsulation; Franklin prices vary. What moves the number:
- How much framing and subfloor is affected.
- Crawl height and how many obstacles, such as ducts and piers, the crew works around.
- Insulation removal and disposal.
- Drainage, from downspout lines to a sump.
- Encapsulation materials and a dehumidifier.
- Carpentry for any softened joists or sills.
For jobs of $25,000 or more, the company needs a Tennessee contractor's license, and mold remediation is the S-F classification.

Local conditions in Franklin
Franklin sits in the Harpeth River watershed and is especially affected by heavy rain upstream. The river reaches flood stage at 30 feet at the gauge near Pinkerton Park. In May 2010, about 16.1 inches of rain fell in two days and the flood displaced hundreds of residents; small businesses along Hillsboro Road were among the hardest hit. The city takes part in the National Flood Insurance Program, offers flood zone determinations and keeps elevation certificates for many properties, all through Building and Neighborhood Services. Property closest to the Harpeth is the most likely to flood, and a standard homeowner's policy doesn't cover it. The same department issues permits for structural repairs and enforces the property maintenance code.
Checklist before the company arrives
- Ask Building and Neighborhood Services whether the house is in an AE or A flood zone.
- Find any elevation certificate for the property.
- Clear the path to the crawl space access.
- Note where water collects in the yard after heavy rain.
- Turn the HVAC off if ducts under the house show growth.
