Marietta shares Atlanta's humid climate but has its own set of mold challenges. The city's mix of established neighborhoods from the 1950s-70s and newer subdivisions means moisture issues show up in different ways depending on when your home was built.
Older Marietta homes near the Square and in East Cobb often have basements and crawl spaces that weren't built with today's waterproofing standards. Newer homes in West Cobb developments can have their own problems — rushed construction and builder-grade materials that don't hold up to Georgia humidity.
Cobb County gets over 50 inches of rain per year. Combined with clay soil that doesn't drain well and summer humidity above 70%, Marietta homeowners deal with mold more often than many realize.
Marietta's suburban homes often have large finished basements and lower levels that are popular for extra living space. These below-grade areas are the most common source of mold problems in Cobb County homes.
Many Marietta neighborhoods were built on sloped lots, which is great for walkout basements but creates drainage challenges. Water flows toward the foundation instead of away from it, especially during heavy rain.
Like the rest of Georgia, Marietta has no state licensing requirement for mold remediators. Every professional in our directory has been verified for insurance, certifications, and customer reviews from the Marietta area.
