Mold in Walls & Drywall in White House, TN

How does water end up inside a wall in White House?

White House is a growing suburb of about 13,000 along Interstate 65, roughly 22 miles north of Nashville. Most homes are on high enough ground that a river isn't the threat, but storms are. On September 1, 2017, flooding closed Highway 31W and Highway 76 in town, and on May 8, 2024, flash flooding pushed water into part of White House High School, including some of the theater, while most of Tyree Springs Road went underwater for a time. When that kind of runoff reaches a house, it can wick into the bottom of drywall. Day to day, the more common sources are slow plumbing leaks, failed window flashing and condensation behind furniture on exterior walls during humid months.

Does it matter which county my house is in?

Yes, for licensing. The city spans Robertson and Sumner counties. Robertson County is on the state's Home Improvement license list, so residential jobs there of $3,000 up to $25,000 need that license; Sumner County isn't on the list. On either side, a job of $25,000 or more needs a Tennessee contractor's license, and mold remediation is the S-F classification. Permits don't change by county: City of White House Planning and Codes on College Street handles building permits through its EnerGov portal for structural repairs after remediation.

How much of the wall will need to come out?

It depends on moisture readings. Crews usually cut past visible growth until the edges read dry, remove wet insulation, and clean and dry the studs before closing up. After floodwater, they cut a level line above the high-water mark. Angi reports a national range of about $1,000 to $20,000 for mold in walls; Middle Tennessee prices vary with square footage, containment and rebuild work.

One local note

The city enforces the 2021 ICC Property Maintenance Code, and its Planning and Codes page has a Report a Concern link, so renters whose landlord hasn't fixed a leak have a place to turn. For health questions, the Robertson County Health Department in Springfield is the local office, and the state's Healthy Homes page covers mold and moisture basics.
