Mold in Walls & Drywall in Chamblee, GA

Why does the lower wall of my split-level smell musty?

Chamblee has many mid-century ranch and split-level neighborhoods built in the 1950s and early 1960s, including Sexton Woods, Keswick Village, Huntley Hills and Beverly Hills. In a split-level, the lower floor is partly below ground, so one or more walls are pressed against soil. When gutters overflow or the yard slopes toward the house, metro Atlanta's slow-draining red clay holds water against that wall and moisture wicks into the drywall from the bottom up. The smell often shows up before any stain, especially behind furniture pushed against an outside wall.

Fixing it usually takes two parts: removing the moldy board, paneling and insulation, and dealing with the water outside through gutters, downspouts and grading. Without the second part, new drywall grows the same mold.

We remodeled the bathroom. Why is there mold in the next wall?

Older bathrooms often had tile set on materials that let water through over time, and remodels sometimes leave old drain or supply joints inside the wall. A slow drip from a shower valve or a toilet supply line can soak the back of a shared wall for months. A moisture meter, a thermal camera or a small inspection cut helps the company see how far it spread before opening up a finished room. EPA says sampling is usually unnecessary when mold is visible, so testing rarely adds much once the wall is open.

I rent in Chamblee. Who handles a leak in the wall?

Notify the landlord in writing and keep a copy. Georgia law (O.C.G.A. 44-7-13) requires landlords to keep the premises in repair, and Georgia does not allow tenants to withhold rent. Georgia DPH says local housing codes generally lack mold standards but points renters to city or county housing code officials, so ask the City of Chamblee which office handles property maintenance complaints. Georgia Legal Aid has a guide on repairs. This is general information, not legal advice.
