Mold Testing in Marietta, GA

Why would a Marietta home need testing?

Marietta, the Cobb County seat about 17 miles northwest of downtown Atlanta, is built around Marietta Square and has six historic districts, including Whitlock Avenue, Church-Cherokee Streets and Northwest Marietta. Older houses there often have crawl spaces, plaster walls and roof joints that can leak for a long time before a stain shows. Sope Creek and Sewell Mill Creek also pass through the area. During the September 2009 floods, National Weather Service gauges listed at Marietta went above flood stage: Sewell Mill Creek crested at 13.26 feet against a 12-foot stage, and Sope Creek at 18.35 feet against 12 feet. When you smell mold but cannot see it, or water got into the house, testing paired with moisture readings can show where the problem is.

How are the results read?

The lab lists mold types and counts, normally beside an outdoor sample taken the same day. Indoor counts above outdoor levels, or types that are rare outside, suggest growth inside. There is no legal pass or fail number; EPA has set no federal limits for mold spores and Georgia DPH says testing has no enforceable state or federal standards. Color is no indicator of risk. A good tester ties each result to a room and to a moisture reading.

What happens after the results come in?

Fix the water source, then get remediation bids from a written scope. For tear-out and rebuilding over $2,500, ask whether the company holds a Georgia residential or general contractor license, check it on the Secretary of State's GOALS Verify Now lookup, and confirm current rules with the state licensing board. The City of Marietta Building Inspection Division enforces the state minimum codes for remodels, plumbing and HVAC work; call the city to confirm permit steps before work starts. A clearance test before new drywall goes up confirms the cleanup. Angi's 2026 national data lists air and surface testing at $250 to $500.
