Mold in a Stonecrest wall means moisture has been getting into the cavity from plumbing, a roof or window, or ground water at a lower wall. The answer is to stop the water, dry quickly, then have the moldy drywall and insulation removed and the framing dried before a permitted rebuild.

About Stonecrest
Stonecrest is a suburban city in the far southeast corner of DeKalb County, about 13 miles from downtown Atlanta, with a smaller section north of I-20. It is the largest city entirely within DeKalb and takes its name from the Mall at Stonecrest. Arabia Mountain and the Davidson-Arabia Nature Preserve sit nearby. Homes here deal with the same moisture loads as the rest of the metro: long humid summers, strong storms and clay soil that drains slowly. Inside, a leaking supply line, tub surround or AC condensate drain is the most frequent reason a wall cavity stays wet long enough to grow mold.
What to do now
- Shut off the water to a leaking fixture, or the main if you cannot find the source.
- Move furniture and belongings away from the wet wall.
- Run fans and a dehumidifier. EPA says drying within 24 to 48 hours helps prevent mold.
- Do not paint, caulk or wallpaper over the stain; EPA warns against covering mold.
- Take photos and note the date you found it.
- If the moldy area is bigger than about 10 square feet, EPA's guide for larger jobs applies, so bring in a company.
- Plan for the rebuild permit. The City of Stonecrest Building Department, 3120 Stonecrest Boulevard, Suite 190, (770) 224-0200, issues interior finish and remodeling permits.

Signs and likely causes
| What you see | Likely cause |
|---|---|
| Bubbling paint on a wall shared with a bathroom | Leaking supply line, valve or drain |
| Dark line along the bottom of an outside wall | Water pooling at the foundation |
| Stain spreading down from the ceiling | Roof, flashing or upstairs plumbing leak |
| Warped trim around a window | Rain entering past the window frame |
| Mildew in a closet with no stain | High indoor humidity and stale air |
Cost factors
Angi's Atlanta cost guide reports most companies charge $12 to $29 per square foot, and HomeGuide's 2026 national ranges put a large wall section at $1,500 to $6,000. Costs depend on the area opened, insulation and framing damage, containment needs and the rebuild. Renters should note that Stonecrest Code Enforcement's listed duties focus on exterior property maintenance, and its page links to the International Property Maintenance Code and the Georgia Landlord Tenant Handbook.
