"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."

"Working with Sean and his team was a great experience and we are very happy with the finished results! Sean came out and tested multiple areas for aesbestos, we didn’t have any but still chose him because we were nervous about dust and mess. After talking to him about the project we knew he was the right choice and would do a great job. Sean and his team did popcorn ceiling removal, flat finish, and paint. It looks amazing. Our project definitely wasn’t easy, we have multiple areas with high ceilings and an atrium that we wanted well protected so the plants wouldn’t die! Would definitely use All4Him again on a future project, highly recommend."

"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."

"I was very pleased with their work. The post-installation test results show that their system is removing the radon from my home. They got the work done promptly and were very easy to work with. And their pricing was lower than anyone else's. I highly recommend Radon Stoppers."

"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."

"Great experience. Robert visited the house, evaluated all potential sources of radon, and provided an estimate for the installation of the mitigation system. He was very thorough and explained the whole process. A week later, his stepson Sy installed the mitigation system. Just like Robert, Sy was very professional and friendly. Last but not least, the mitigation system works great. Before the installation, the radon level was 7.9 pCi/L, after installing the mitigation system, levels dropped to 1.2 pCi/L. <br />"

FAQs for radon gas testing projects in Saint-Paul, 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.
