Mildew in a Hermitage home, on a shower wall, in a closet or under a window, is often a small job the owner can clean once the dampness is fixed. If it spreads past about 10 square feet, gets into drywall or carpet, or followed water coming in during a storm, it is time for a pro.

Hermitage at a glance
Hermitage grew from rural land in eastern Davidson County into a suburban district with everything from starter homes to executive houses, and about 48 percent of households in ZIP 37076 rent. Only about 26.5 percent of homes in the ZIP were built before 1980. The Stones River runs between Hermitage and Donelson through the Clover Bottom bottomlands, and Stoners Creek crosses the ZIP. In the March 2021 storms Hermitage measured 7.16 inches of rain, and a Kroger on Old Hickory Boulevard flooded with stalled cars outside.
With so many renters, a lot of mildew here shows up in apartments, where the bath fan, the windows and the plumbing belong to the landlord, so a lasting fix often depends on getting the owner involved.
What to do now
- Check the size. EPA treats patches under about 10 square feet as something most owners can clean.
- Gear up with gloves, goggles and an N-95.
- Scrub hard surfaces with detergent and water.
- Dry the area completely, then keep it dry with fans or a dehumidifier.
- Throw out moldy cardboard, rugs or ceiling tiles.
- If you rent, tell the landlord in writing and keep a copy.
- If it returns, look for the moisture before cleaning again.

Signs and likely causes
| What you see | Likely cause |
|---|---|

| Mildew behind a dresser on an outside wall | Cool wall, no air movement |

Cost factors
Angi reports national typical ranges of $500 to $1,000 for bathroom mold remediation and $1,223 to $3,758 for remediation overall; Middle Tennessee prices vary with size, material removal and access. Containment for larger areas and fixing the leak itself add to the total. In Davidson County, residential jobs from $3,000 to under $25,000 require the state Home Improvement license, and bigger jobs need a contractor's license. Rebuilding that goes past normal maintenance needs a Metro Codes permit, and renters can report unrepaired leaks to Metro Codes Property Standards through hubNashville.
