Is radon a concern in Atlanta?

Metro Atlanta is Zone 2 — moderate risk. The northern suburbs like Roswell, Alpharetta, Marietta, and Kennesaw tend to test higher due to proximity to the Appalachian foothills. Testing is recommended for all homes in the metro area.

Which parts of Georgia have the highest radon?

North Georgia has the highest risk. Counties in the Blue Ridge mountains and foothills — Fannin, Union, Lumpkin, Dawson, Gilmer, Pickens — are Zone 1. The Piedmont region including parts of metro Atlanta is Zone 2.

Does Georgia require radon testing when buying a home?

Georgia does not legally require radon testing in real estate transactions, but it is increasingly common and strongly recommended — particularly in north Georgia and the northern Atlanta suburbs.

How many radon contractors serve Georgia?

Georgia has 25 certified radon professionals across 16 cities, with the highest concentration in metro Atlanta. The Atlanta metro area alone has about 20 contractors serving the region.

How much does radon mitigation cost in Georgia?

Most Georgia homeowners pay between $1,200 and $2,800. Crawlspace homes in north Georgia may need additional encapsulation work alongside the mitigation system.

Do I need radon testing in Georgia before hiring a contractor?

Yes. A valid short-term or long-term test is the fastest way to confirm if mitigation is needed and to scope the right system design.

How do I choose a certified radon contractor in Georgia?

Look for current NRPP or NRSB credentials, ask for post-mitigation test expectations, and confirm local compliance details. Georgia does not have state-specific radon licensing requirements beyond national certification. NRPP and NRSB credentials are the standard for Georgia radon professionals.

EPA recommends action at 4.0 pCi/L, and many homeowners choose to reduce levels even below that threshold. Northern Georgia along the Appalachian foothills has Zone 1 counties — including Fannin, Union, Lumpkin, and Dawson. Metro Atlanta sits mostly in Zone 2 with moderate risk. Southern Georgia below the Fall Line is Zone 3 with generally lower levels. ZIP-level lookup tools are useful for local context, but home testing is still required.
