Frequently Asked Questions about Radon in the Atlanta Metro Area
Common questions about radon testing, mitigation costs, and health risks for homeowners in the Atlanta Metro metropolitan area.
Why are radon levels so high in the Atlanta Metro area?
Radon levels in the Atlanta Metro area are driven by the local soil and bedrock composition, which contains naturally occurring uranium. As uranium decays, it produces radon gas that migrates upward through the soil and enters homes through foundation cracks, sump pits, and gaps around pipes. Homes with basements and crawlspaces are especially susceptible because these below-grade spaces are in direct contact with the soil where radon concentrations are highest.
How much does radon mitigation cost in Atlanta Metro?
Professional radon mitigation in the Atlanta Metro metropolitan area typically costs between $800 and $2,500, depending on the size and construction of your home. The most common approach is an active sub-slab depressurization system, which a certified contractor can usually install in a single day. Ongoing energy costs for the mitigation fan are minimal—roughly $5–$10 per month—and most systems reduce radon levels by 90% or more.
Are landlords in Georgia required to test for radon?
Radon testing and disclosure requirements vary by state and municipality. Some Georgia jurisdictions require landlords to disclose known radon levels or test results, while others have no mandate. Regardless of local law, the EPA recommends radon testing for all residential properties—including rentals—since radon is the second leading cause of lung cancer in the United States.
Can I sell a house with high radon levels in the Atlanta Metro area?
Yes. High radon levels do not prevent a home sale, but buyers in the Atlanta Metro market routinely request radon testing during the inspection period. If levels exceed 4.0 pCi/L, the buyer may negotiate for the seller to install a mitigation system before closing. Having a radon mitigation system already in place can actually be a selling point, demonstrating proactive home maintenance and providing documented proof of safe indoor air quality.
