"Radon levels were over 7 at the new house we bought. Andrew installed a radon mitigation system and brought the levels down below 2.0. Andrew and co-worker were great to work with. They installed a standard system that they provided as estimate for up front. They provided 2 test kits to check the results after the work was done. When I screwed up the tests, they provided 2 more kits."

"Radon Stoppers did a great job installing a radon mitigation system in our home in Minneapolis. It was very straightforward to get an estimate and schedule the installation. Pat was happy to explain how a radon mitigation system works and where it would be installed. They guarantee that the system will reduce the radon to a safe level for the quoted price with no surprise charges, and also provide a 5 year warranty. We are very happy with our new radon mitigation system."

"Walt and his crew did an amazing job mitigating radon from our basement! Radon level went from 4.4 pCi/L to 0.3. Out of 3 bids, he was the only one to come to our house to look at how to route the system. He wasn't in a hurry and explained everything to me in layman's terms. On the day of the install, they arrived promptly and explained what they were going to do. They suggested testing out the sump pump before they sealed up the area and I realized it wasn't working. I purchased a new sump and they even helped me put it in! Wasn't expecting that kind of service. Would highly recommend Advanced Radon Services."

"Rick and crew kept at it after first effort resulted in still-too-high radon levels. This if not uncommon, and Rick added solutions until a good test was achieved, at no additional cost. Would highly recommend."

"We wanted to reduce the presence of radon in our house. Andrew came out for the estimate and gave us a general idea of what to expect - what they would do initially as well as future steps in necessary as each home has it's own uniqueness. There estimate was in line with the other we received and decided to go with them. Josh and Andrew installed the exterior fan and interior piping - quickly and completely cleaned up when finished. They noted how import it was to have the foundation sealed. As we were waiting for the test results, I noticed that under our basement shower there was a dirt floor - a remodel in our old home long before we arrived. Our post mitigation test confirmed this opening was sucking air out of the basement rather than under the slab. They gave me the option of sealing it myself or having them do the work. I wanted to stay with the estimate so I did it myself. They instructed me on what to do and stressing the importance of getting all of it sealed. Wrapping up a long story, I got it sealed off and the follow up test had our radon results down to 0.7 - from 6.6 before the installation."

FAQs for radon gas testing projects in Clear Lake, MN

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.
