How is radon tested in Milwaukee homes?
A certified tester places a professional continuous radon monitor on the lowest livable level of the home for at least 48 hours under closed-house conditions. Milwaukee Radon Mitigation in West Allis, WI, led by NRPP-certified Brian Thompson, runs these tests across Greater Milwaukee and explains results against the EPA action level of 4.0 pCi/L.
Why Every Milwaukee Home Should Be Tested
Radon cannot be seen, smelled or tasted, and the EPA names it the second leading cause of lung cancer after smoking. Wisconsin DHS estimates about 1 in 10 Wisconsin homes has high radon, and levels can differ sharply between neighboring houses.
Age, style and location do not tell you your level. New homes, old homes, homes with and without basements can all test high. A test takes a couple of days and gives you a real number to act on. Learn more from Wisconsin DHS and the City of Milwaukee Health Department.
Professional Radon Testing With Digital Continuous Monitors
Do-it-yourself kits have their place, and Wisconsin’s Radon Information Centers offer low-cost kits. Professional radon testing adds three things a kit cannot.
Hour-by-hour data
A continuous monitor records radon every hour instead of giving one average. We can see daily swings, spot spikes and check that conditions stayed steady during the test.
Faster answers
No mailing a kit to a lab and waiting. Results are ready right after the test of at least 48 hours ends, and we walk you through them.
Correct placement and conditions
We place the monitor on the lowest livable level, away from drafts, sumps, exterior walls and humid spots, and give you written closed-house instructions so the result holds up, including in a real estate deal.
After the test you get a written report: your average level, how it compares to 4.0 pCi/L, and honest next steps. If you need a system, we explain options. If not, we tell you when to retest.
Radon Testing for Homes, Home Sales, Businesses and Daycares
Homeowners: One test on the lowest livable level is usually all you need to start.
Buying or selling: Radon testing is not required for real estate in Wisconsin, but DHS highly recommends it. DHS guidance calls for a test of at least 48 hours, closed-house conditions starting 12 hours before, on the lowest livable level. We work to your inspection deadlines, deliver real estate retest results within 72 hours, and our written reports are accepted for real estate transactions. With your permission, we can share the report with both agents. See real estate radon testing.
Commercial buildings: Offices, retail, multifamily buildings and condo associations need several monitors placed by floor area and HVAC zone. See commercial radon testing.
Daycares: Since March 2023, Wisconsin DCF requires licensed child care providers to test for radon and mitigate above the EPA action level. We test licensed child care centers, home daycares and schools, with after-hours visits when needed.

Radon Testing FAQs
What is the average cost of a radon test?
A professional radon test in the Milwaukee area costs more than a DIY kit because it includes a certified tester, a professional continuous monitor and a written report. Our price for a standard home test is $150. DIY kits are cheaper; Wisconsin Radon Information Centers offer low-cost kits. See our radon testing cost guide.
How long does a professional radon test take?
A professional radon test with a digital continuous monitor runs at least 48 hours, which also meets Wisconsin DHS real estate guidance. Long-term tests of 90 days or more are also available. Because the monitor records hourly data, your results are ready as soon as the test ends, with no lab wait, and we explain them on the spot.
How do I prepare my home for a radon test?
Keep windows and exterior doors closed for 12 hours before the test and throughout it, except for normal entry and exit. Run heating or cooling normally, but avoid whole-house fans and window fans. Do not move the monitor. These closed-house conditions follow Wisconsin DHS guidance.
How often should you test for radon?
Test any home that has never been tested, and retest after major renovations, a new addition or a finished basement. If you have a mitigation system, the EPA recommends retesting every two years to confirm it is still working. Testing in a different season can also give a fuller picture of your level.
