Decatur's older Craftsman homes and bungalows most often grow mold in crawl spaces, around old bathrooms and below leaky windows and roof lines. The cleanup only holds if the moisture source is found and fixed first. Call the number on this page to be connected with a local mold remediation company in Decatur.

Historic houses near the Square
Decatur incorporated in 1823 and is the county seat of DeKalb County: a small, walkable city built around Decatur Square, about 6 miles from downtown Atlanta, with roughly 24,900 residents at the 2020 Census. A large share of its housing is historic. The MAK Historic District is known for early 20th-century Craftsman homes, and Oakhurst and Ponce de Leon Court have many bungalows. Winnona Park and Midway Woods round out the older neighborhoods.
Why older bungalows get damp underneath
Many older homes in metro Atlanta were built over vented crawl spaces. In July and August, outdoor air is warm and humid. It moves into the crawl space, touches cooler surfaces such as ductwork, water pipes and the underside of the floor, and leaves condensation behind. Over a summer, that can wet insulation and wood enough for mold to grow. Add a slow drip from an old drain line or a downspout that dumps beside the foundation, and the problem gets worse.
What a crawl space check should cover:
- Standing water or wet soil, especially near downspouts.
- Fallen or damp insulation between joists.
- Sweating ducts and pipes.
- Dark growth on joists, sill plates and the subfloor.
EPA says moisture control is the key to mold control. Indoor humidity should stay below 60 percent, and wet materials should be dried within 24 to 48 hours.
Getting a permit in Decatur
Decatur takes building permit applications only through its online CommunityCore portal; there are no paper or email applications. Questions go to the permit technician at [email protected] or (404) 377-6198. The permit pages sit in the city's Design, Environment and Construction section. Rebuilding walls, replacing subfloor or new ductwork after remediation may need a permit, so settle that before work starts.
Code enforcement and renters
Decatur's Code Enforcement is housed in the Public Works Department, and the city has adopted the 2021 International Property Maintenance Code with Georgia amendments. Georgia DPH says indoor air quality is not a regulated program and that local housing codes generally lack mold standards, but leaks, roof problems and failed plumbing are the kinds of repairs landlords must make under O.C.G.A. 44-7-13. Send repair requests in writing and keep copies. This is general information, not legal advice.
Cost and credentials
Angi's Atlanta cost guide reports crawl space remediation at $587 to $2,348 and notes crawl space encapsulation starting around $5,000. Georgia has no state mold license or certification. For jobs that include rebuild work, ask whether the company holds a Georgia residential or general contractor license and check it on GOALS Verify Now. An independent inspector can confirm the space is dry and clean before insulation goes back.
