"<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 />"

"We are first-time home buyers, so home inspections and the entire process of buying is new to us. The Edick team (our inspector was Erik) thoroughly inspected our new home and provided extensive details on issues both large and small. He provided a comprehensive, easily-readable report that included photos, extent of damage, steps to repair and estimated costs for any/all needed fixes. While the amount of information was overwhelming, Erik was more than open to any and all questions and allowed us time at each phase of the inspection to ask for clarification and any additional details. I couldn't be happier with the outcome of the inspection and the kind of immediate trust and report that is needed for this type of process. They were available for immediate follow-up questions after the inspection and gave a full list of trustworthy contractors for any of the needed fixes that we came across. I couldn't recommend Edick more to anyone that is making their first or future home purchase. They are the real deal. Kind, courteous, professional, timely."

"From calling for info to getting booked, everything was clearly explained and we felt very prepared for the appointment. We were able to get booked just a few days after we called. Quoted price was about $1100, and we were happy to move forward with their quote versus others we called. Install was great. Nick arrived and got right to work, listened to concerns about placement, and walked me through everything as he was planning to go. Measured thrice, cut once! From beginning to end, with a few snags in the process due to stucco exterior and numerous utilities packed into the space he was working, he was done in just over 3 hours. Impressive work, and very professional. Guarantee to get numbers for radon below 4.0, and 5 year warranty for the fan. Ended up having to upgrade to a bigger fan due to the hard ground under the slab, and that made the price go up a bit, but still within our budget. Only complaint is that we weren't made aware that this was a possibility going into the appointment, but can't say we didn't want the upgrade--without it our system wouldn't have be adequate to mitigate. Happy so far with everything, and looking forward to the free test kit in a week to see how much better we are in readings. Finished basement means we'll be down there a lot, so we were very happy with how everything went so far, and look forward to living in a safer house thanks to SWAT!"

"They did a great job. They were courteous and explained everything clearly. Quote was reasonable. Provided quality service. They were late for work due to one of the crew member's truck not starting and they did not call us. I had to call them. Otherwise, they were great."

"Dean initially came out and did a thorough work up of what would be required to install drain tile, poly sheeting, seal a crawl space and install a radon mitigation system to lower radon levels that we had tested at 6.5 pCi/L to below 4.0. Included in the bid was to install a new sump pump sealed with a Lexon cover and hook up a battery back up for the pump. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />The work was completed on time according to the detailed contract. The workers were very friendly and though the project took two days, kept the area clean. A post radon test done with a continuous radon monitor which ran for 51 hours prior to final payment revealed an average radon level of 1.0 <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />Excellent workmanship and customer service. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />"

FAQs for radon gas testing projects in Cass Lake, 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.
