Black mold removal in Gallatin means drying the house, containing the affected rooms, cutting out colonized drywall and insulation, and cleaning framing and crawl space wood. Dark color doesn't call for a lab test; EPA says visible mold usually doesn't need sampling. Call the number on this page to be connected with a local mold remediation company in Gallatin.

Local conditions in Gallatin
Gallatin, the Sumner County seat about 24 miles from Nashville, sits on Station Camp Creek, with Town Creek near downtown, Rankin Branch, and Old Hickory Lake about 3 miles south. In May 2024, normally dry Town Creek overflowed after hours of rain. The Barton Drive neighborhood was hit hardest, with water under and into homes and crawl space HVAC units and ductwork ruined; one resident said the water ran higher than in 2010. In May 2017 Station Camp Creek spilled onto Lower Station Creek Road and homes on Cumming Lane flooded. When water sits under a house like that, black growth on joists, duct wrap and the backs of walls often follows within days.
Gallatin's housing is fairly new, with a median year built of 2002, but newer houses still sit over crawl spaces and slab edges that collect water when drainage fails.
Clean it or remove it?
| Material with dark growth | Usual approach |
|---|---|
| Tile, glass, sealed countertops | Clean with detergent and water, dry fully |
| Solid wood framing and joists | HEPA-vacuum, clean, dry; replace only if rotted |
| Drywall and its paper facing | Cut out past the stain and replace |
| Fiberglass insulation, carpet and pad | Bag and discard |
| Flex duct and duct insulation in the crawl space | Usually replaced after flooding |

Signs worth acting on
- Black spotting low on walls after a storm.
- A musty smell when the AC starts.
- Dark growth on crawl space joists or duct jackets.
- Bubbling paint or soft baseboards.
- Black staining on the subfloor around the water heater or washer.
Any of these after a creek rise or a heavy storm is worth a look under the house, even if the living space stayed dry.
Timing and seasons
Speed matters after flooding: EPA says items that can't be dried within 24 to 48 hours should be treated as moldy. Summer is when humidity under the house peaks and dark growth spreads fastest. If walls or ductwork are replaced, City of Gallatin Building Codes handles permits inside city limits. Tenants with poor housing conditions can contact Gallatin Code Enforcement, run through the Gallatin Police Department, by phone or online form. Jobs of $25,000 or more need a Tennessee contractor's license with the S-F mold remediation classification.
