Clearance testing is the independent inspection and sampling done after mold remediation to confirm a Union City home's work area is clean and dry before it is closed up. It is scheduled while containment and air filtration are still running. Call the number on this page to be connected with a local mold inspector in Union City.
Union City is a fully urban city in south Fulton County, about 12 miles southwest of downtown Atlanta. Homes here face the same metro pressures as their neighbors: humid summers, red clay that holds water near foundations, and air conditioners that run much of the year. Those conditions can leave framing wet long after the mold itself is scrubbed off. A clearance test is how you find that out while the wall is still open, instead of a year later when a stain bleeds through fresh paint.
What to do now
- Ask the remediation company to leave the plastic and negative air machine running after cleaning.
- Confirm in writing that the source, such as a roof, plumbing or condensate leak, was repaired.
- Dry the area until wood and drywall edges read normal on a moisture meter.
- Hire your own clearance tester rather than one chosen by the remover.
- Agree on what counts as a pass before anyone takes a sample.
- Rebuild only after the lab report shows a pass, and pull permits for drywall or framing if required.
What you see and the likely cause
| What you see | Likely cause |
|---|---|
| Stains on joists that survived cleaning | Growth not fully removed by sanding or scrubbing |
| Damp smell in a closed room | Hidden wet material or a second source nearby |
| Water marks under the attic air handler | Clogged condensate line or cracked drain pan |
| High indoor spore count on the lab report | Settled dust or debris left inside containment |
| Readings that rise after rain | Gutters, grading or foundation leaks still letting water in |
Cost factors
Price is mostly the number of samples and visits. HomeGuide's 2026 national ranges list air sampling at $100 to $300 per test and surface sampling at $50 to $200. More sealed rooms mean more samples, and a failed result means a second visit. After a pass, the Union City Community Development Department Building Permits Division handles permits and inspections for building, electrical, plumbing and HVAC work. Ask any rebuilding contractor whether it holds a Georgia residential or general contractor license and check it on the Secretary of State's GOALS Verify Now lookup.
