Mold in a Canton wall usually means water has been getting into the cavity from a plumbing, roof or window leak, or from moisture through a lower wall. The fix is to stop that water, remove affected drywall and insulation under containment, and dry the framing before rebuilding. Call the number on this page to be connected with a local mold remediation company in Canton.

Is it growing inside the wall?
Probably, if a stain grows or returns after cleaning, paint blisters, drywall feels soft, or one wall smells musty. Mildew on a bathroom wall that cleans up and stays gone is a surface issue. A company will use a moisture meter, often a thermal camera, and sometimes a small inspection hole to find where the wet area starts and ends. EPA notes that sampling is usually unnecessary when mold is visible.
Canton is the Cherokee County seat, a city of about 33,000 people roughly 34 miles north of Atlanta. It was a mill town, home to Canton Denim until the mills closed in 1981, and has grown into a fast-growing I-575 suburb with a revitalized downtown around Main Street. The Etowah River flows east to west through the middle of the city, and in September 2009 the NWS listed a gauge in the Etowah basin near Canton above flood stage; Cherokee County was one of four Georgia counties designated for FEMA Individual Assistance. Older mill-era homes may have plaster walls, while newer houses tend to have more plumbing inside walls.
Will the county or city get involved?
Cherokee County Environmental Health, at 1130 Bluffs Parkway, receives mold complaints and gives information but does not inspect residences, because there are no enforceable mold standards. Georgia DPH says the same about indoor mold statewide. That makes cleanup a private job. If the rebuild may need a permit, check with the City of Canton before work starts.
Who should rebuild the wall?
Georgia has no state mold license or certification. Rebuilding is construction work, and Georgia law defines a residential contractor by work over $2,500, so ask whether the company holds a Georgia residential or general contractor license and check it on GOALS Verify Now. Angi's Atlanta cost guide reports most remediation pros charge $12 to $29 per square foot, plus $1,174 to $3,405 for drywall repair.

A local note
If a home near the Etowah took on water, have lower walls opened and dried rather than simply repainted; EPA says to assume mold when wet materials could not be dried within 24 to 48 hours.
