Post-remediation clearance testing confirms that a mold-cleaned area in a Duluth home or apartment is clean, dry and comparable to outdoor air before containment comes down. A tester inspects, measures moisture and sends samples to a lab. Call the number on this page to be connected with a local mold inspector in Duluth.

What happens when you call
The call connects you with an independent local mold inspector serving Duluth. You'll be asked what was removed, how many rooms are inside containment, what caused the moisture and when drying ended. The inspector then schedules a visit before the plastic comes down. They examine the area for leftover growth and dust, measure moisture in studs, joists and subfloor, take indoor air samples and an outdoor sample on the same day, and swab cleaned surfaces. Once the lab reports, results are compared with the pass criteria you set in writing, and you receive a report you can keep.
What drives the cost
- Number of contained areas and samples. HomeGuide's 2026 national ranges list air sampling at $100 to $300 per test and surface sampling at $50 to $200.
- Whether ducts or the air handler were part of the work area.
- Access to attics and crawl spaces.
- A second visit if any area fails.

Local conditions
Duluth sits in Gwinnett County about 23 miles northeast of downtown Atlanta. Like the rest of the metro it has hot, humid summers, red clay that drains slowly and air conditioners that run much of the year, with ductwork often routed through attics or crawl spaces. Those conditions make condensate overflows and slow plumbing leaks common starting points for mold, and they can leave framing damp after cleanup. Most construction work in the city requires a permit from the Duluth Planning and Development Department; the Building Official is at 770-476-1790. The city also runs a Multifamily Housing Inspection Program, approved in 2018, under which owners of four or more rental units must provide a code compliance certificate, with a share of units inspected each year. Renters with an unrepaired leak can contact Duluth Code Compliance through its online portal or at compliance@duluthga.net. GNR Health's online complaint categories do not list residential rentals or mold.
Checklist before the tester arrives
- Leave containment sealed and air filtration on.
- Do not paint or seal anything inside the work area.
- Gather the remediation scope, photos and invoice.
- Note the moisture source and the repair made.
- Agree on pass criteria and retest cost in writing.
