In Gallatin, mold testing is most useful after a cleanup, to confirm the work, or when a musty smell has no visible source. If flood water soaked a crawl space or walls and couldn't be dried within 24 to 48 hours, EPA says to assume mold and plan cleanup without waiting on a lab. Call the number on this page to be connected with a local mold inspector in Gallatin.

Local conditions in Gallatin
Gallatin sits on Station Camp Creek, with Town Creek near downtown, Rankin Branch, and Old Hickory Lake about 3 miles to the south. Two recent floods show how water reaches homes here. In May 2017, Station Camp Creek spilled onto Lower Station Creek Road and homes on Cumming Lane flooded. In May 2024, normally dry Town Creek overflowed after hours of rain, and the Barton Drive neighborhood took water under and into houses; owners there lost crawl space HVAC equipment and ductwork. That kind of event is where sampling earns a place, both to check rooms that never looked wet and to confirm the crawl space came back clean after the work. The city's median home was built around 2002, so many houses are fairly new but still sit low enough to take creek water.
Inspection or test?
| Mold inspection | Mold testing | |

| Best for | Planning cleanup after a leak or flood | Hidden-growth questions and post-cleanup checks |
| National range (Angi) | $303 to $1,075 | About $250 to $500 |
| Limits | Can't see inside closed walls without meters or openings | No federal limits to judge results against |

Signs to mention when you call
- A smell that comes through supply registers when the HVAC starts.
- New ductwork or insulation was installed after a flood and the odor returned.
- Stains near the floor on lower walls in rooms closest to the creek.
- Condensation on windows or a hygrometer that won't drop below 60 percent.
Timing
Book clearance sampling after remediation is finished but before new drywall or flooring goes in. For a stale-air question with no flood, test when the house has been closed up under normal conditions rather than right after airing it out. Rebuilding inside city limits needs a permit from Gallatin Building Codes on West Main Street, and tenants with unrepaired leaks can file a complaint with Gallatin Code Enforcement through the police department. If the crawl space HVAC was replaced after a flood, ask the tester to sample near the new supply registers as well as in the rooms; a smell that rides the airflow often starts below the floor rather than in the room where you notice it.
