Radon Mitigation in Syracuse, NY

Radon Mitigation in Syracuse, New York

Syracuse and Onondaga County fall in EPA Radon Zone 2, with elevated radon risk driven by limestone and shale bedrock and a climate that keeps homes tightly sealed for much of the year. Central New York homes — particularly older properties in Syracuse's historic neighborhoods — frequently test above the 4 pCi/L EPA action level.

Why Syracuse Homes Test High

Central New York sits atop sedimentary geology that includes limestone, shale, and salt deposits — formations that produce radon at moderate to elevated levels. The Syracuse metro's housing stock skews older, with full basements ubiquitous across the region. Homes in Dewitt, Fayetteville, Manlius, and Liverpool consistently produce test results that warrant professional mitigation.

Like all of Upstate New York, Syracuse homes are sealed tightly from November through March. Indoor radon concentrations measured in winter regularly run 1.5–2x higher than summer readings.
