Conditions come before products
The mold you can see is only part of what's happening. A solid plan chases the moisture back to its source, weighs humidity and material condition, contains the work, and confirms results afterward.

Columbus context
Humid Georgia heat supplies the moisture and the building supplies the cold surface. Through the cooling season, warm outdoor air drawn into crawl spaces meets framing at ground temperature and condenses on it for months, so a space can be thoroughly wet with no leak and no plumbing failure. Red clay beneath holds water for days after the heavy storms this river valley gets, keeping that supply constant. Mature tree cover slows drying on every shaded elevation. The heating season then runs the same process in reverse and upward, so a bath fan discharging into the attic rather than through the roof marks the sheathing every winter until the duct is fixed.
