"I had been working with another radon mitigation company. The owner seemed knowledgeable, but after coming to the house for the estimate he ghosted me. So I called Professional Radon Systems. They were wonderful to work with. They arrived at the scheduled time, told me what needed to be done, and made an appointment to do it. Two fantastic young men showed up when they said they would, did the work, explained everything, and that was that. Great company! I appreciate the professionalism and the high quality work."

"Matt from Bull’s Eye Home Improvement was very attentive, responsive, and cordial throughout the quote and inspection processes. I would recommend him. In addition, his home inspection report was very well done, easy to interpret, and quickly delivered."

"Phenomenal service from Bill & Jose! My townhome tested high for Radon during my move in inspection and I'm so glad I found American Radon Systems to do the mitigation. Bill was super communicative and attentive. They did a fantastic job matching the color of the gutters and styling it to sit flush on the house, it looks great on outside and is completely hidden inside of our home. Great company to do business with if you are in the Chicagoland area."

"The guys came out within a day or two of my initial call and spent quite a bit of time explaining what they would do. They were patient and seemed very knowledgeable. Their solution involved routing the exhaust through the garage and garage attic and out the roof, which would be much more attractive and less subject to weather extremes than routing the exhaust pipe along the exterior of the house. After I gave them the go ahead, they were able to schedule the work within 1-2 weeks. They arrived on time and were very efficient, finishing a little earlier than I had expected. In addition to the radon remediation they patched a foundation crack for considerably less money than companies that specialize in foundation repair."

"Working with BRT on our home inspection and radon test was incredibly easy and very competitively priced. Dave was very easy to get a hold of and was able to schedule us quickly. He is very knowledgeable about homes and construction in general. He not only showed me certain issues with the house but also explained which items I could fix myself and where to buy the parts. He differentiated the items that couldn't be "DIY-ed" and offered to provide (didn't push) contacts for these items. The best value with BRT is the fact that they can couple a radon test with their home inspection. Most home inspectors sub-contract their radon tests with different companies. This not only adds time to your inspection (cutting into your inspection review period) but also costs a lot more money (I quoted 5 different home inspectors and BRT was the most competitive). To top it all off, Dave is a personable guy who is very easy to get along with and has plenty of experiences to share. I would highly recommend Dave and BRT to anyone getting a home inspection (especially if you're getting a radon test too)."

FAQs for radon gas testing projects in Plainfield, 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.
