Kennesaw at a glance
Kennesaw, once called Big Shanty, is a suburban city of about 33,000 people roughly 23 miles northwest of downtown Atlanta, next to Kennesaw Mountain National Battlefield Park and home to Kennesaw State University. Butler Creek has an NWS gauge listed at Kennesaw, and during the September 2009 floods it crested at 14.27 feet against a 12-foot flood stage. Rain like that tests every roof, and attics with air handlers and ducts face condensation through each summer. Two-story homes with bonus rooms over the garage add knee walls and tight corners where damp air gets trapped and growth goes unseen.
What to do now
- Look for the moisture source near the growth: a leak, a duct, the AC pan, a fan outlet.
- If the HVAC equipment is in the moldy area, do not run it until it is checked, as EPA advises.
- Leave large patches undisturbed and keep the attic hatch closed.
- Take photos of the attic and any ceiling stains.
- Schedule the source repair and the cleanup.
- Renters should notify the landlord in writing. Kennesaw Code Enforcement handles private property concerns through the city's online portal, and the city has adopted the 2024 International Property Maintenance Code.
