Although no homeowner wants to increase cancer risks for family members, many people neglect to test their homes for radon, an invisible, odorless, cancer-causing gas that emanates from soil and rocks. Contacting a radon mitigation specialist to perform a radon test, or conducting your own test with a DIY radon test kit is the first step in protecting your family from hazardous levels of radon gas.

Proven radon testing & radon abatement in Minnesota

According to the Minnesota Department of Health, two in five MN homes have radon levels that pose a significant health risk - and almost 80 percent of counties are rated high radon zones.

Radon levels in Minnesota vary, but you have a right to know your home's level of this toxic gas. Radon is the leading cause of lung cancer for non-smokers in the U.S., and since it is produced from soil it can find its way up through gaps and cracks and enter into the air you breathe inside your home.

Although radon may not be the most well-known home issue, it's no secret that radon knows how to hide. As an odorless, tasteless, colorless gas, radon cannot be traced by the human senses, but it can be detected by a professional radon test and can be mitigated and reduced to a healthy level.

As a former Realtor, I was impressed with the mitigation system. The crew was very professional and on time. I was happily surprised with how quiet the exhaust fan was. I have seen other systems and the fans are fairly loud. This one is whisper quiet. I strongly recommend them, Roger Ness

Jeremy, I received my test results from Alpha yesterday. You probably did as well. I am rather pleased with the results. To go from 13.4 pCi/L in January 2014 to 0.7 pCi/L in 2017 is amazing. I would assume you are pleased as well. Thanks again, Keith

I recently had Jeremy from Twin Cities Radon do the Mitigation work in my home. I called 3 other contractors and they wanted to figure it out when they came to do the job and just gave me the price over the phone. Price was not a concern for me as they were all within a few hundred dollars of each other. What mattered most was that I felt confident in the person doing the work. Jeremy took the time to come out 2 weeks ahead of the job so he knew exactly what he was getting into. I appreciated that and it gave me the confidence I needed that he would do it right and get my radon levels under 2. I also liked that he was the one coming back to do the work and not sending someone else. I knew I made the right decision when I told him he could have the job. At this point I was buying Jeremy more than I was a mitigation system. I was impressed with the fact that he did everything he said he was going to and explained it very well in advance. I had a lot of questions and called him a few times after his first visit. He always took the calls and explained everything in detail. The day of the job he arrived promptly at 9am as he said he would. The job went very well and he was done by 3pm. I was very impressed with the clean up he did. Would have never known someone had been here drilling and doing all that he did. So many contractors fall short on some of these things and it lowers my confidence in them and their work. I did the 2 day radon test and Jeremy promptly emailed the results. I was pleased to see my radon levels both upstairs and downstairs were 0.5. When I first started looking into what was involved with doing the Mitigation System last month it all seemed overwhelming to me. Once I made contact with Jeremy I realized that in the hands of an expert this was no big deal. It was a problem that could easily be corrected if you were working with a seasoned professional that knew exactly what they were doing. My Veterinarian in Watertown was very pleased with Twin Cities Radon and had recommended them to me. I too would highly recommend Jeremy and Twin Cities Radon to anyone who needs a Mitigation System in their home. Thanks for your professionalism, your high quality of work and your follow through with every detail as you promised. You are a man of your word and that speaks volumes for your company. I have no doubt if I ever have an issue with the system that you will be there to take care of it. Many thanks for a job extremely well done Jeremy. Pat from Howard Lake

Hi Jeremy, The Radon test results from July of 2020 showing levels of 3.0. The after result of .08 is impressive!

Twin Cities Radon did a great job on our radon system. It looks great and our radon levels are low now. Jeremy was very professional and did a nice job cleaning up too. I was also surprised how it reduced not only my radon levels, but it reduced the musty smell in my basement. I'd recommend Twin Cities Radon Services highly!
