"A1 and Andrew were great. Returned my call right away, gave me a fair bid, what I should expect, and a date to come out. They called ahead of time, and did quality work. Don’t hesitate to use them. I got lucky. I found out I had lung cancer and did a radon test. Don’t hesitate to do a radon test, and use A1 if appropriate. Thanks."

"Sean was very nice to us. We were afraid of having asbestos on one part of the house and he was patient enough to answer all of our questions. We had an area tested and he was on time for the testing and we got the results when he said we were going to."

"It went smooth and thorough and he gave us the information we needed to know. I was wanting to schedule something soon and they were able to come out two days after I inquired their services! Cant beat that. We also got a phone call explaining everything that was found for the air quality test and where to go from there. All their help was very much appreciated."

"Professional in every aspect. The owner, Walt Fitzmaurice, is very knowledgeable and took the time to explain what would be done and when. Top marks for communication, timeliness and quality of work. Easy, no pressure sale. Walt and his crew did an amazing job mitigating radon from our basement! Very respectful working in the house, and there was nothing for me to clean up after they left. All around a good experience. Walt left a measurement device to assess success of the mitigation. Radon level went from 5.8 pCi/L to < 0.3 pCi/L. Two visits (quote, installation) and it was done. Walt 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, at 09:15 and explained what they were going to do. No electrical work was required. Existing outlet in attic from a 1985 project. The vent pipe runs from a basement store room into the attached garage and to the attic where the fan is located, the roof vent is on the back side of the garage and is not noticeable. You cannot hear any fan noise. The installation was finished by 2:00 p.m. I would highly recommend Advanced Radon Services."

"Another contractor said I may have clay under my basement floor and that the above mentioned type of system would not work. Mr. Frank from EES did more testing and analysis and said he could make it work. In fact, he only had to install one suction point in the floor and none in the walls to make it work. Apparently the first company that checked my basement did not drill their test holes in the right spots. <br /> Before mitigation the radon level in the basement was 7.2 pCi/L and after the job was done it was 1.3. He guaranteed a level below 3.0.  <br />"

"These guys are wonderful people and great to work with! They really go above and beyond, where do I start...Firstly, Midwest Radon does things right. I had multiple bids to install a new radon system in our house we just purchased as the levels came in higher than what the EPA considers safe. They guaranteed radon levels below 2 pCi/L, which was the lowest levels when comparing bids. Secondly, Jack, John, and Mike are all professional and flexible to the homeowner's needs. Communication and timeliness was not an issue at all, they kept me informed and showed up when they said they were. Midwest Radon told me that they will pull the appropriate permits, and get an electrician to install the outside outlet to power the system. Not all of the other contractors were going to pull the permits and get an electrician to do the work, these guys do it the right way! Not to mention, Midwest Radon's bid was extremely fair, considering the additional cost of the permits and the peace of mind that you get with someone from the city coming out to make sure the work is completed within code. Once the work was done, they cleaned up well. Other than the visible radon mitigation system, I couldn't tell they drilled two holes in my basement to complete the install. Lastly, I had an issue with a neighbor about the radon system. John and Mike were more than happy to make a trip to my house to figure out a solution (free of charge) that works for myself and my neighbor, which we ultimately did. Never, did I feel dismissed by them or I wasn't as important as someone who is about to pay for a new system. I'm confident that if I ever have any other issues, I could call them and they'd be willing to do anything reasonable within their control. The biggest shame is that these guys only install radon mitigation systems, I'd be comfortable using them with any work that needs to be done in my house."

"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."

FAQs for radon gas testing projects in Chaska, 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.
