Mold Remediation in Marietta, GA

Cobb County knows what its creeks can do. During the September 2009 floods, the U.S. Geological Survey found that flooding on Sweetwater, Butler, and Powder Springs creeks far exceeded the estimated 500-year flood, and Noonday Creek, which runs through northeast Cobb, also flooded severely. Cobb County reported that the 2009 flooding reached more than 1,600 homes countywide. Most Marietta mold jobs are smaller than that, but the pattern is the same: water that sat in a house for more than a day or two.

Creek-side homes

Creek water is treated as contaminated, so crews cut drywall and insulation above the water line, remove soaked carpet, pad, and lower cabinets, and dry the wall cavities before cleaning. If your home sits near Sweetwater, Noonday, or Sope Creek, check whether it lies in a FEMA flood zone; that decides which insurance policy responds.

Finished basements

Many Marietta and East Cobb homes have finished basements that seep after long rain. The work opens the lower walls, removes wet pad and insulation, dries the concrete and framing, and depends on fixing the water path, such as grading, gutters, or foundation drainage. Our basement mold guide covers the options.

Older homes near the Square

About a third of Marietta's homes were built before 1980 (Census ACS). Older houses around Marietta Square often sit over crawl spaces, where humid summer air condenses on ducts and framing. Crawl space remediation removes wet insulation, cleans or replaces affected wood, and adds a vapor barrier or drainage fix. See crawl space mold.

Attic air handlers

An attic unit that overflows onto the ceiling below is one of the most common small jobs: ceiling drywall and insulation out, framing dried, and an HVAC fix so it does not repeat.

Hiring in Cobb County

• No license exists for mold work in Georgia, so the paperwork is your filter: an insurance certificate, proof of crew training, and the scope in writing.
• Base every bid on an independent mold inspection in Marietta.
• If walls, floors, or cabinets get rebuilt and the bill tops $2,500, the builder needs a Georgia contractor license, which the Secretary of State's site can confirm.
• Close the job with an independent check; mold testing in Marietta covers how.

What it costs

Cobb County jobs are priced off metro Atlanta guides (2025–2026): roughly $1,250 to $4,500 for most homes, or $10 to $25 a square foot. Expect more when creek water or a finished basement means rebuilding afterward; the remediation cost guide breaks it down.

When you call

Start with where the water came from (creek, basement wall, or attic unit) and how long ago. You will hear what the local company recommends next and what it charges, with no fee for the call.

Georgia does not license mold remediators. In Marietta, ask for liability insurance, crew training such as IICRC certification, and a written scope; check any rebuild contractor's Georgia license for jobs over $2,500.
