Radon Mitigation Across Southeastern Wisconsin
Wisconsin has some of the highest radon levels in the nation. According to the EPA, nearly 1 in 15 homes in the U.S. has elevated radon levels — and in SE Wisconsin, that risk is even higher due to local geology and soil composition. Whether you’re in a Milwaukee suburb, a Waukesha lakeside community, or a Racine County home, indoor radon is a silent threat you can’t see or smell.
Wisconsin Radon & Environmental has spent over a decade protecting homes and businesses throughout the greater Milwaukee area. Our NRPP-certified technicians use proven sub-slab depressurization systems designed specifically for Wisconsin’s soil and basement conditions — ensuring your radon levels drop well below the EPA action threshold of 4 pCi/L.
Frequently Asked Questions About Our Service Area
Do you serve rural areas and small towns in SE Wisconsin?
Yes. In addition to the cities listed above, we regularly serve surrounding townships and rural communities throughout SE Wisconsin. Call us to confirm availability for your specific address.
How soon can you come to my area for a radon test?
We typically schedule radon testing within 1–3 business days throughout our service area. Short-term 48-hour electronic testing is available for most locations, with same-day reports delivered digitally.
Does radon risk vary by county in Wisconsin?
Yes. Certain areas — including parts of Waukesha, Washington, and Ozaukee counties — show higher average radon concentrations due to granite and sand-gravel soil. All Wisconsin homes should be tested regardless of location.
Do you offer commercial radon services across all listed counties?
Absolutely. We provide commercial radon mitigation, radon testing for schools, and multi-family building services across all 10 counties in our service area. Contact us for a custom commercial quote.
