New York City Metro, NY Radon Information

The New York City Metro metropolitan area in New York has a regional average radon level of 6.4 pCi/L based on 59 user-submitted tests. This exceeds the EPA’s recommended action level of 4.0 pCi/L, meaning radon testing and professional mitigation should be a priority for homeowners across the region.

Radon is a naturally occurring radioactive gas produced by the decay of uranium in soil and bedrock. In the New York City Metro area, local geology and common residential construction—particularly homes with basements and crawlspaces—allow radon to seep indoors and accumulate to dangerous concentrations. Particularly high readings have been recorded in communities like Brooklyn, Brewster, Yorktown Heights, where professional radon testing and mitigation services are strongly recommended.

Whether you are buying a home, selling a property, or simply want to protect your family, a professional radon test is the only way to know your home’s levels. If elevated radon is found, a licensed mitigation contractor can install a sub-slab depressurization system—typically in one day—to reduce levels by up to 99%. Request a free radon mitigation quote

Frequently Asked Questions about Radon in the New York City Metro Area

Common questions about radon testing, mitigation costs, and health risks for homeowners in the New York City Metro metropolitan area.

Why are radon levels so high in the New York City Metro area?
Radon levels in the New York City 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 New York City Metro?
Professional radon mitigation in the New York City 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 New York required to test for radon?
Radon testing and disclosure requirements vary by state and municipality. Some New York 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 New York City Metro area?
Yes. High radon levels do not prevent a home sale, but buyers in the New York City 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.
