Removing it means fixing the moisture, cutting out moldy drywall and insulation, and drying the framing before the wall is closed.

Local conditions in Thompson's Station
Thompson's Station is a town with railroad-era roots between Franklin and Spring Hill, about 26 miles from Nashville, and the site of the 1863 Battle of Thompson's Station. In the May 2010 flood, about 14.4 inches of rain fell here over two days. Williamson County emergency management lists the Harpeth River and its creeks as the county's main flood sources, warns that flash floods can come with little warning and suggests checking FEMA's Flood Map Service Center for your property. For most homes, wall mold has a smaller cause: a drip from a fitting inside the wall, a window or door that leaks in driving rain, or humid air condensing in a closet on an exterior wall.
Clean the surface or open the wall?

|---|---|---|
| Where the growth is | On paint, tile or grout | Behind drywall, inside the cavity |
| Moisture readings | Normal after cleanup | Elevated in the drywall |
| Drywall condition | Firm | Soft, crumbling or stained through |
| Odor | Gone after cleaning | Persists or returns |
| History | Shower steam only | Leak, flood or repeated staining |

Signs worth checking

- Warped or separated trim.
- Musty air in a room no one uses much.
- Paint peeling around a window or door frame.
- Spots on the drywall inside a sink cabinet.
Timing and seasonal notes
Try to dry any wet wall within 24 to 48 hours, as EPA recommends; past that, assume mold may be starting. Spring storms and summer humidity are when most wall problems show up. Angi's national range for mold in walls is about $1,000 to $20,000, and prices in Middle Tennessee vary. If framing needs replacing, building permit applications and plans go to the Town of Thompson's Station, where Planning and Codes review them together. Jobs of $25,000 or more need a Tennessee contractor's license with the S-F mold remediation classification. Health questions can go to the Williamson County Health Department in Franklin. Before signing, ask the company to put the cut lines, the drying target and the rebuild responsibility in writing, so you know exactly what the price covers and who closes the wall.
