"The service was for Radon Mitigation in our home that had higher than acceptable Radon levels. The work was professionally done, and care was taken to protect carpeting etc during their work. The crew updated us home owners as they did their work and asked permissions for needed modifications to the house. I would recommend this company to anyone looking for quality workmanship, congenial communication and moderate pricing."

"Our first radon result was 10.4, which was tested by another local company. We ordered a different test (a link on Athelon's website) to confirm the number, which was 7.7 (U.S. EPA acceptable level for indoor radon is <4.0 pCi/L). We had 3 companies review our situation and provide quotes. Athelon's quote was in the middle, about $100 more which was negligible. Dan Hylland was the only one who suggested an interior route could be an option through a closet, into the attic, and through the roof (vs venting it out at essentially ground level and then running the pipe up the side of the house and 18" above the roof, which would be an eyesore). However, on the day of installation, there were a ton of obstacles that prevented them from starting the internal route right away. But Dan was super thorough and did his due diligence to make the internal route work, which was totally worth it so we don't have a 4" pipe jetting out the side of our house and upward 18" beyond the roof. Athelon did a fantastic job and I would recommend them in a heartbeat."

"<p>it was superb! they easiest, hassle free Radon test in town, with extremely proficient people -- very knowledgeable and very people-friendly! they took their time to explain things on the phone to me before I committed. the test came back within 10 days or so -- via email. which is very convenient. it was very clear as it is, but I like talking through it and get advice. they were instantly available to discuss. they gave me future tips to keep on top of all things Radon related. </p> <p>I have to say that all this comes to be after 3 months of many back and forths with 3 other companies -- none of the other companies could be bothered to schedule a time, and those who did, never showed up.. many times over. I don't know why I was so patient with them and I wish had discovered Environmental Testing & Research Laboratories much sooner.</p> <p>Really highly recommend them!</p> <br />"

"Jamie gave us the good news and bad news. They also did a refrigerant charge on my old unit to get us by until they were able to install the new AC and furnace. Also caught the need for grounding of our gas line to bring it up to current building code."

"Everything went splendid with K&S, and without them, I may still be without heat (in Minnesota, in March). Brian spent way more time than he should have had to, dealing with a lazy home warranty company, and ensuring that I knew that they were trying to give me a cheap replacement for the first rate unit that was there. He took the time to school me on what to tell them, so I didn't sound like the ignorant homeowner that I was . I now have a super efficient brand new Lennox furnace in my home, thanks to K&S heating. I was so impressed with their service, I applied to work there."

"Our house was built in 1941. We not only felt we needed to do waterproofing but needed a radon extracting system, sump pump, dehumidifier, wall paneling and new windows with window wells. The project worked like clock work with members of the American Waterworks team. Only have 3 windows and small section of paneling to finish. Paneling can't be finished until new water line is installed. All will be completed when windows arrive. In 1 yr. American Waterworks will come back to check all is working well. Extensive project that wasn't cheap. We felt we got our money's worth!"

FAQs for radon gas testing projects in Dakota, 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.
