Kennesaw in brief
Kennesaw is a suburban city about 23 miles northwest of downtown Atlanta, home to Kennesaw State University and next to Kennesaw Mountain National Battlefield Park. Butler Creek runs through the area; during the September 2009 floods, the National Weather Service gauge on Butler Creek listed at Kennesaw crested at 14.27 feet against a 12-foot flood stage. Most crawl space mold here comes from more ordinary sources, though: humid air, slow-draining clay and leaks. Hilly lots near the mountain and the ridges around it can send runoff toward foundations, and a crawl space on the downhill side of a house often stays wet long after a storm passes.
What to do now
- Check for an active leak under sinks, at the water heater and along the AC condensate line.
- Walk the outside of the house during rain to see where gutters and downspouts send water.
- Don't pull insulation or scrub large patches yourself; that spreads spores.
- If ducts under the floor look moldy, follow EPA and keep the HVAC off until they are checked.
- Keep anyone with asthma or a weakened immune system out of the area.
- Photograph what you see and note when the smell started.
- Renters: notify the landlord in writing and keep a copy.

What you see and the likely cause
| What you see | Likely cause |
|---|---|
| Mud lines or silt on the soil | Water that entered during heavy rain or flooding |
| Sweating ducts and wet insulation below | Humid air meeting cold ductwork |
| Growth concentrated under one bathroom | Plumbing leak above |
| Musty odor on humid days | Outdoor air entering through vents |
| Dark staining on sill plates | Water wicking from the foundation or poor grading |

Size, access, insulation removal and framing replacement drive the number, and moisture control adds to it.

Kennesaw's Code Enforcement Division handles private property concerns through the city's online portal. Cobb & Douglas Public Health says it has no authority over mold in private homes or rentals.
