Kenosha sits on Lake Michigan at Wisconsin's southeastern border with Illinois, in Kenosha County. The area is classified EPA Zone 2 (moderate predicted radon), though sources occasionally disagree. Southeastern Wisconsin's glacial-till deposits and dense lake-shore basement housing stock combine with Wisconsin's long winters to drive elevated radon readings in many homes regardless of zone classification.
Geology: Kenosha's cold winters drive sustained stack-effect-driven radon influx during closed-house conditions.
Permits: Wisconsin does not require state-level licensing for radon mitigation. City of Kenosha / Kenosha County standard building permits may apply.
Neighborhoods we serve in Kenosha: HarborPark, Allendale, Library Park, Lincoln Park, Brass, Wilson Heights, Forest Park, Downtown Kenosha.
All Kenosha radon work is performed by NRPP/NRSB-certified partner contractors routed through Wisconsin Radon Experts. Wisconsin does not require a state radon contractor license — national NRPP/NRSB credentialing is the consumer-protection standard.
Kenosha County averages pCi/L indoor radon — well above the EPA action level of 4 pCi/L. Here's how Kenosha's radon profile compares to other Wisconsin cities we serve.
| Metric | Kenosha, WI | Wisconsin State Average | US National Average |
|---|---|---|---|
| Average indoor radon | null pCi/L | 5.7 pCi/L | 1.3 pCi/L |
| EPA Radon Zone | Zone 2 | Zone 1 (26 of 70 counties, 37%) + Zone 2 (44, 63%) | Varies (Zones 1–3) |
| % homes elevated (>4 pCi/L) | null% | ~10% (1 in 10) | ~6% |
| Multiple of EPA action level | 0.0x | 1.4x | 0.3x |
| EPA action level | 4.0 pCi/L | 4.0 pCi/L | 4.0 pCi/L |

Learn more →Wisconsin Statute § 709.03 requires sellers to disclose any known radon information via the Real Estate Condition Report (Form WB-3). In practice, most Kenosha real estate transactions now include a radon contingency in the purchase agreement — and given that % of Kenosha homes test elevated, buyers are increasingly insisting on pre-closing mitigation when results exceed 4 pCi/L.
Our partner contractor network handles closing-timeline mitigations within typical 7–14 day windows, including post-mitigation verification testing to satisfy lender and inspector requirements.
Yes. Kenosha's cold Wisconsin winters intensify radon entry through the stack effect — heated indoor air rising creates negative pressure in basements that pulls soil gas into the home at higher rates than warmer climates. Kenosha winter radon readings are typically 30–50% higher than summer readings.
EPA recommends radon testing under closed-house conditions, which align naturally with Kenosha winters. If your Kenosha home tested low in summer, retest in winter for an accurate baseline before deciding on mitigation.
