"Dave Masa was first recommended by our realtor. I then had a meeting with an attorney who also offered his name as the go to guy for this type of work. I then checked Angie's list and found that others also thought highly of the work performed by Radon Reduction Systems. We received both a verbal and detailed written bid for an external system that was accepted. I was particularily impressed with his written promise that his work would be honored (warrantied) for five years and would extend to the new home owner following the home sale. <br /> A few days after Dave's inspection, I asked him to return to our home to review the possibility of installing an interior system. Not only did we he believe the interior system would be feasible, he indicated that the price would not change. We're delighted with the result. It is easy to describe the work performed. It was efficient, timely, and professional in quality. Care was taken to place the piping in areas that did not interfere with daily living. The work was completed (by 2 people) in approximately 4 1/2 hrs. <br />"

"<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 />"

"Denny has been extremely thorough and he spent over 4 hours to inspect my house. He took time to explain how the house works and possible maintenance and improvements. He even went a lot of extra miles in testing the appliance, which is out of the scope of home inspection. His report was so timely, professional and easy to read. After that, he was extremely responsive and helpful to advising the basement leak he found. He has been a great advisor. I am so glad I hired him for my home inspection! I would highly recommend him regardless you are experienced or inexperienced home buyer like myself. <br />"

FAQs for radon gas testing projects in Emden, IL

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.
