"Andrew is top notch in my book, and I am so very glad that I hired him. I was told by another professional a long time ago that I needed two suction points since I had two cement slabs, and Andrew assured me that it typically is not needed, and if it is for some odd reason it won't cost me anything more than what his original quote was. All questions answered with confidence. I was notified when he would arrive on the day that was agreed. The suction point was discussed and ultimately my own locations he selected without argument he worked with me and suggested area's that would work out. He assured me that if the levels of radon are not below 2 then he would come out again to modify the size of the fan and or add another suction point. when he started working once the suction location was agreed upon, work went very fast with his assistant outside and Andrew in the basement holes drilled suction tubing installed and vented exactly where I wanted it. Outstanding job Andrew!!!! "

We provide high quality, fully insured, certified radon services to the Twin Cities Metro & surrounding areas. Our #1 priority is our customers satisfaction. We're happy to educate anybody who's interested in radon, please feel free to give us a call with any questions.

"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."

"John Loomans unduly influenced my buyers against buying my home due to wiring. I subsequently had my wiring inspected by two master electricians both of when said the wiring was up to code in my state and didn't pose a danger. Loomans cost me a $455,000 sale. People need to understand the the home inspection industry is completely unregulated, allowing inspectors to say anything they want, true or not, without recourse."

Radon Detection and Reduction questions, answered by experts

Short-term tests take 2-7 days, while long-term monitoring may require up to 90 days for accurate results.

Costs for radon detection services typically range from $150 to $250, depending on the testing method and whether a professional assessment is required.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Since radon typically comes out of the soil, it is most commonly found in the lower levels of a home. In houses with basements, that's a common location for radon. Homes built directly on the ground may have radon on the ground floors. Radon can be found on the upper floors of the home, but often in lower concentrations than in lower levels.

What is radon? It’s a radioactive gas that naturally occurs in the ground, forming as uranium and thorium decay. It has no color or odor, so you don’t know if it’s seeping into your building’s foundation. Regular exposure to radon gas increases your chances of suffering from lung cancer. Radon testing measures the air inside your house for the presence of radon gas. If detected, the test will measure the severity of radon levels in your home’s air.
