In Hermitage, crawl space mold usually comes from humid summer air condensing under the house, poor drainage after heavy rain, or plumbing leaks, with extra risk on low lots near the Stones River and Stoners Creek. Removal means cleaning the framing, taking out wet insulation and fixing the moisture. Call the number on this page to be connected with a local mold remediation company in Hermitage.
Hermitage at a glance
The Stones River separates Hermitage from Donelson and winds through the Clover Bottom bottomlands, and Stoners Creek also runs through the 37076 ZIP. In the March 2021 flash flooding, Hermitage measured 7.16 inches of rain and a Kroger on Old Hickory Boulevard flooded. Housing here is newer than much of Davidson County, with about 26.5 percent built before 1980, but newer crawl spaces still get damp when drainage or vapor barriers fail. A builder-grade plastic sheet that was never taped at the seams, or a lot graded so that rain runs toward the foundation, is enough to keep the soil under a 1990s house wet for most of the spring.
Steps to take now
- Look for the obvious: water pooling near the foundation, overflowing gutters, a downspout without an extension.
- Listen and look for drips under kitchens, baths and the water heater.
- If you suspect the ducts under the house are moldy, follow EPA's advice and don't run the system until it's checked.
- Leave the growth alone; dry scraping or brushing spreads it.
- Check Metro Water Services' flood maps or Parcel Viewer to see whether your lot is in a mapped flood hazard area.
- Book an inspection that includes wood moisture readings and photos.
Nearly half of homes in ZIP 37076 are rented. Renters should give the landlord written notice of leaks or water under the house; if nothing happens, Metro Codes Property Standards takes complaints through hubNashville.
Reading the signs
| What you see | Likely cause |
|---|---|
| Sweating ducts and wet joists in August | Humid air meeting cold surfaces |
| Puddles after storms | Grading, gutters or drainage |
| Sagging, dark insulation | Long-term moisture |
| Mud or debris on the ground cover | Surface water getting in |
Cost factors
Angi reports national ranges of about $500 to $2,000 for crawl space mold remediation and $1,500 to $15,000 for encapsulation. Middle Tennessee prices vary with the size of the space, how much material comes out, drainage work and whether a dehumidifier is installed. Davidson County requires the state Home Improvement license for residential jobs from $3,000 to under $25,000; above that, the company needs a Tennessee contractor's license with the S-F mold remediation classification. Replacing load-bearing framing needs a Metro Codes permit.
