"It went great. I highly recommend them. They were a pleasure to deal with. The person that came out for the estimate answered all of my questions. The estimate was fair. The work was done on schedule and with no problem. At completion, everything was explained to me. I used their electrician which worked out fine. After completion the radon test showed that my level was now undetectable."

"I had PureTech install a radon gas abatement system which lowered my levels from the high teens all the way down below 2 on average. Zach, the technician, was super helpful and great to work with. They even leave this really nice package behind. Results speak for themselves. I recommend PureTech."

"Tim was on time and finished early. Nice, neat install. I can't be absolutely sure how accurate my radon detector is but before the install the highest short- term reading I saw was 7.94. After the install I haven't gone over 2 and usually is 1.5 or lower."

"It was a noisy, messy process that took most of a day, but after installation of the radon mitigation system by RMES our basement radon levels went from 4.2 pCi/L to 0.4 pCi/L. The system has also helped to reduce the relative humidity and mustiness in your basement. All parts have worked reliably with no issues since March 2016. Would recommend RMES to others seeking radon mitigation."

"I called David asking for a Radon test, within 45 minutes he arrived at my house. After he performed the test, we decided to have a unit installed. From start to finish David & his team was nothing but professional. I highly recommend David Cook Radon Services. 5 stars…Thanks again"

"WI Radon and its owner Jerome were fabulous. He was so knowledgeable about our specific radon mitigation needs. He worked with us closely to customize the system that would best work for us. We were so impressed with the entire process from initial testing to the final inspection of our new system. We would recommend him first if you suspect you have radon issues."

"We need a quick turnaround after our house tested high for radon during a home inspection. The owner Don was super responsive with the initial quote and was right on top of every from start to finish. Got our installation scheduled right away and blew away the tight timeline we were facing with closing approaching. I hope I only need one remediation system in my lifetime but if I ever had to use his services again, this would be the first spot I would call."

FAQs for radon gas testing projects in Pewaukee, WI

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
