"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."

"<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 />"

"I invited three different providers for an estimate on a radon mitigation system. Tom at Ameradon provided a competitive estimate and was the only one who spent a lot of time explaining the options and how exactly he would go about installing it. Tom came on time on the specified date and went about his work. He is very thorough and clean in his approach and pays a lot of attention to detail. After installing the system, we tested the radon levels again. It had gone down just below the state limit, but Tom was not satisified. He offered to put in an extension for an additional fee of about $100 - this was not much because he had to put in more than 4 hours of additional work to do this - plus, there would be no charge if there was no drop in the radon level. We tested the radon level again and there was no difference, so Tom offered to come back a third time - after he spent time discussing with experts at the MN state government. Tom came for a third time in November and put a fan with the appropriate capacity and also found a leak in a hard-to-detect place. After this effort, the reading came down significantly and only then did Tom accept the additional fee. One of the other providers had quoted me an all inclusive fee that was significantly more, but I doubt if they would have come through like Tom. During the work, Tom went out of his way to keep the job site clean and also did some extra work to erect and quot;cardboard wallsand quot; in the garage attic to prevent insulation from falling on the floor. <br /> During the work, we got to chat and I discovered that Tom does this because he loves helping solve this dangerous problem in homes. He does make a living out of it, but that is not his primary driver for doing this job. I would definitely use Tom again in the future should the need arise. <br />"

"They arrived promptly, checked the furnace and then found a part that needed replacement. They made a temporary fix until the needed part was ordered, arrived, and then they called to install the new part. All in all, they were very professional, helpful, and followed up with the part installation. I would recommend them for any heating or air service. <br />"

"I am very pleased with them.  They did a very good job.  The drain tiles work awesome.  We had pretty heavy torrential rain and there was no drop in my basement at all.  They did a great job.  They are very friendly.  They communicate exactly what they are going to do.  They explain why the system is different then and what other systems are available and they were accurate when they said that.  They are always available.  They were very responsive."

"Very well. Had multiple people out to evaluate my water issue in the lower level of our home. Hired these guys because they seemed to have the most reasonable solution for my issue. In the end they had to do a core drill to allow the water to drain from my block and install the Safe Edge system to prevent any future water from entering my lower level. Called in October, couldn't actually perform the work until December due to how busy they were."

"I was disappointed in the beginning when I didn’t receive a response from the sales rep after 3 contact attempts. It turned out he left for another job. The reason for us hiring them is because we really liked his business ethics and trusted him based on his military background. They office staff was very professional in handling the matter and reassured me the work would be complete to high standards. I wasn’t present but my husband said they were very professional. They worked hard to keep things clean and were accommodating to the needs of our pet birds who required that the furnace remain on. However I’m dissapointed that they did not discuss if they completed the radon testing or not like they said they would. The only other issue is that we did financing through them and they needed a paper signed. Instead of leaving the dorm with us the first day to give them the second they gave it to us the second day which meant my husband had to take more time off to drive to my work to have me sign it then drive it back to them before returning to work himself. I’m not 100% sure if I’d hire them again. It depends on if we find out if they did the radon testing or not."

FAQs for radon gas testing projects in Madelia, 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.
