Mold inside walls in Spring Hill homes nearly always follows water: a hidden leak behind a tub or sink, rain getting in around windows, condensation, or flooding like May 2010, when the Duck River overran parts of the city. Removing it means stopping the water, cutting out moldy drywall and insulation and drying the framing. Call the number on this page to be connected with a local mold remediation company in Spring Hill.

Signs mold is in a Spring Hill wall
- A musty smell that greets you when you open a closet or bathroom door.
- Dull, chalky or blistered paint over one area.
- Staining that spreads outward from a corner or window.
- Gaps opening between the baseboard and the floor or wall.
- A surface that feels damp on humid days.
- Spots on stored boxes or the backs of furniture along an outside wall.
Local conditions in Spring Hill
Spring Hill is a fast-growing city about 29 miles south of Nashville that spans Williamson and Maury counties and is home to the GM Spring Hill plant. In the May 2010 flood, about 13.2 inches of rain fell over two days and the Duck River overran parts of the city. Water that sits against drywall gets drawn up into the wall and the insulation behind it. In a city that has grown this fast, many owners are in houses where a construction miss, such as a poorly flashed window or a nail through a supply line, first shows up as a wall stain.
The city's Building Department checks construction for conformance with the National Flood Insurance Program and FEMA rules along with the city's Unified Development Code, so ask there before rebuilding a flood-damaged wall.

What affects the price
Angi reports a national range of about $1,000 to $20,000 for mold in walls, and Middle Tennessee prices vary. The size of the cut, wet insulation, containment, tile or cabinets in the way, and whether finish work is included decide where a job lands. Jobs of $25,000 or more need a Tennessee contractor's license, and mold remediation is the S-F classification; check any company on TDCI's Verify a License search. Angi also suggests using a separate company for testing and remediation, so the final check is independent.
What happens when you call
You'll be connected with an independent local mold remediation company. Tell them which county your address is in, where the problem is and what water the wall has seen. Expect moisture readings, photos and a written scope. Framing repairs need a permit from the City of Spring Hill Building Codes and Inspection Department. Renters with unfixed leaks can contact the city's Codes Enforcement Division through its Citizen Portal. For health questions on the Williamson County side, contact the Williamson County Health Department in Franklin.
