Mold Testing in Kennesaw, GA

Kennesaw in brief

Kennesaw, once called Big Shanty, sits 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, and during the September 2009 Atlanta floods its National Weather Service gauge at Kennesaw crested at 14.27 feet against a 12-foot flood stage. Homes range from older houses near Main Street to subdivisions and rentals near the Town Center area and the university.

What to do now

1. Find and stop any active water: check sinks, toilets, the water heater, the washer and the air handler drain.
2. Write down where and when the odor is worst, and photograph stains with the date.
3. Do not clean, bleach or paint suspect areas before sampling if you need documentation.
4. Dry what you can. EPA advises drying wet materials within 24 to 48 hours and keeping indoor humidity below 60 percent.
5. If the AC seems to be the source, hold off on running it; EPA warns a contaminated system can spread mold.
6. Renters should report the problem to the landlord in writing.
