Local conditions in Antioch
Antioch, about 9 miles from downtown in southeast Metro Nashville, grew from a rural village into one of the city's biggest suburban areas. In the Antioch (Priest Lake) area, about 64 percent of homes were built before 1980, and the housing mix includes detached houses (about 59 percent), townhouses and attached units (about 23 percent) and mobile homes (about 11 percent). Older systems, ducts in crawl spaces and mobile home ducts inside the belly wrap all collect moisture in a humid summer. Mill Creek runs through the area, and in May 2010 its Antioch gauge set a record crest of 26.10 feet. During the March 2021 flash flooding, vehicles were stranded on I-24 near Harding Place and Mill Creek rose sharply again. Ductwork under a floor that took water in either event should be checked, even if the house was repaired and the smell seemed to fade years ago.
What's at stake in each housing type
| Home type | Where duct mold tends to start |
|---|---|
| Older house over a crawl space | Sweating supply ducts and loose, wet duct wrap under the floor |
| Townhouse or attached unit | Air handler closet, drain pan and ceiling boots, sometimes from a neighbor's leak |
| Mobile home | Ducts in the belly under the floor, where a plumbing leak keeps insulation wet |
| Home near Mill Creek | Duct runs and equipment that sat in floodwater |
Signs
- Musty air when the system kicks on, especially on humid days
- Growth on register covers or inside the return
- Water under the air handler or a ceiling stain near a vent
- Torn or soggy duct insulation under the house
Timing
Summer is when hidden problems surface, but don't wait for the next heat wave. After any flood, EPA says to assume mold if things weren't dried within 24 to 48 hours. Metro Water Services' flood maps show whether an address lies in a FEMA Special Flood Hazard Area, though Metro notes homes outside it can still flood. Renters can report an unrepaired leak to Metro Codes Property Standards through hubNashville. In Davidson County, residential jobs of $3,000 or more call for the state Home Improvement license, and you can check any company on TDCI's Verify a License search.
