"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."

"We were looking for a next-day inspection, and House Detective was the first firm to respond to the emails we sent out. Because we weren’t working off a referral, we didn’t know what to expect, but Kevin exceeded our expectations! He arrived on time, provided an overview of the inspection plan, highlighted the issues he’d be highlighting in his report during the inspection and generally inspired confidence. Although the firm charges a flat rate for inspections, Kevin spent an hour longer than planned with us, answering all of our questions. We were incredibly lucky to have chosen House Detective and will definitely recommend Kevin to our friends!"

"The Gaidish crew arrived early and completed all work in three days. They attached a plastic film around the perimeter of my basement to minimize dust and did a wonderful job cleaning up. We've had some heavy rains since then and my basement was dry for the first time in many years. Although I was completely satisfied with the work, I was most impressed with the time the owner Jeff took to answer some questions. I had stopped by the Gaidish office on a Saturday morning and although Jeff had already left, someone called him and he returned, opened the office and he proceeded to answer my questions. I certainly wasn't expecting that! These are the people you want working on your foundation/Basement problems. You won't be disappointed!"

"I used this company for my furnace/central air cleaning and they were very professional as well as for this job.  Mike arrived on scene and suggested some things to me and got the job done within an hour.  I will use them again in the future.

FAQs for radon gas testing projects in North Prairie, 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.
