Mold in Walls & Drywall in Austell, GA

Signs to look for

• A tide line on drywall at the height water reached
• Baseboards that are swollen, split or dark along the top
• Paint blistering or peeling low on exterior walls
• A musty smell that comes back each humid season
• Soft drywall or loose tape at the seams
• Spots behind furniture on lower-level walls

Why Austell walls get wet

Austell is a small south Cobb city about 15 miles from downtown Atlanta, with a small piece in Douglas County. It grew up around a rail junction on level ground along Sweetwater Creek, a tributary of the Chattahoochee. That setting brings water close. In the September 2009 floods, Austell was among the hardest-hit places, with five major streams overflowing. National Weather Service gauges listed at Austell recorded Sweetwater Creek cresting at 30.80 feet against a 10-foot flood stage and Olley Creek at 27.40 feet against 12 feet, and NWS says the Sweetwater Creek basin rose to the 500-year flood level.

Not every wet wall comes from a flood. Heavy summer storms, gutters that dump water at the foundation, and leaks from supply lines or tub drains cause most wall mold. If a home took water in 2009 and walls were closed before they fully dried, old growth may still be inside.

What affects the price

Angi's Atlanta cost guide reports $12 to $29 per square foot for remediation and $1,174 to $3,405 for drywall repair. HomeGuide's 2026 national ranges run $500 to $1,500 for a small drywall section and $1,500 to $6,000 for a large wall section. Flood jobs usually cost more because the cut runs the length of every affected wall, insulation comes out and the framing needs longer drying.
