Clearance testing is the independent inspection and lab sampling that confirm a mold-cleaned area in a Dunwoody home or apartment is clean and dry before containment is removed. It is the step between the end of remediation and the start of the rebuild. Call the number on this page to be connected with a local mold inspector in Dunwoody.
Dunwoody is about 14 miles north of downtown Atlanta. Its neighborhoods took shape from the 1960s onward, with subdivisions such as Georgetown mixing single-family homes and apartments. Houses and apartments of that age have often had roofs, windows and plumbing repaired more than once, and slow leaks behind walls are a common starting point for mold.
What to do now
- Keep containment and air filtration running after the crew finishes cleaning.
- Get written confirmation of what caused the moisture and how it was repaired.
- Dry the framing until readings are normal; summer humidity can stretch this out.
- Hire a clearance tester yourself. Angi recommends separate companies for testing and removal.
- Agree on pass criteria in writing: no visible growth, dry materials, indoor air close to outdoor air.
- Rebuild only after a pass, and check with Dunwoody Permits and Inspections ([email protected], 678-382-6821) about drywall and framing permits.
What you see and the likely cause
| What you see | Likely cause |
|---|---|
| Fresh staining on a ceiling below a bathroom | Tub, shower pan or supply line leak above |
| Damp drywall edge near a window | Failed flashing or caulk |
| Spore count indoors well above outdoors | Debris left inside containment or a missed hidden area |
| Moisture readings that won't drop | Leak still active or dehumidifiers removed too soon |
| Musty smell from supply vents | Moisture or growth in the air handler or ducts |
Cost factors
Expect the number of sealed areas and samples to drive the bill. HomeGuide's 2026 national ranges list air sampling at $100 to $300 per test and surface sampling at $50 to $200. A retest after a fail adds more. For renters, note that Dunwoody's tenant resources list mold as a non-enforceable code violation, while interior water leaks, roof disrepair and broken gutters are enforceable by Code Enforcement; report those through the Central Square portal or the Compliance Hotline at 678-382-6890.
When you book the visit, ask the tester for a report that lists each sample location, the moisture reading at each spot, and the lab results side by side with the outdoor sample. A report laid out that way is easy for a landlord, buyer or rebuilding contractor to read, and it shows plainly whether the area met the agreed standard.
