"Ross called back within 30 minutes and set up an appointment for the same week at my convenience. He was extremely professional and very easy to work with. He was on time both time he had to be in my home. I had my results in my email within a few hours of him picking up the sensors. I truly appreciate his time and explanations. I would definitely recommend Ross and Boomtown Radon Testing without hesitation."

"Very easy to get an appointment on short notice when I had limited time to get a radon test done in the process of purchasing a home. Their price was also slightly lower than an estimate I'd received from another company, and the technician was more thorough about explaining the process than the other company I considered."

"I had a hard time contacting this company at first but when they finally responded, the service was great. Chuck met with me and explained what he thought would work best for the crawlspace in our new home. We originally wanted to install drain tile to avoid any possible water seepage in the future but he told us it wasn't necessary. Unlike PermaSeal who tried to sell us everything under their roof! Buyer beware of PermaSeal! Anyway, Chuck offered to provide a payment plan since we couldn't afford it all in one lump sum. We had a few issues at the beginning with things unrelated to them but Chuck was very responsive and advised us regarding some issues with our village permit. Even though we called and e-mailed him several times in one day, he maintained his great customer service. We finally scheduled an appointment and then had to re-schedule which they accommodated. The day they showed up, they came a bit late but Chuck sent a message letting us know. He showed up to check out the installation as well and warn us of the strong smell of the foam to see if we wanted to leave the house. We stayed but the foam smell was very strong for a few weeks and even up to today, we have not used it yet due to the smell. We may not end up using the crawlspace for storage as originally planned because we've noticed there's still a lot of insects getting through there since we left the entrance open for the smell to dissipate. Well, the crawlspace looks good and we are very happy that they installed a light switch by the entrance and a bulb in the middle so we could see the entire space if we want to go in there. We also got excited when Chuck mentioned they would do a radon test to show us the difference with the insulation. This has not been done yet but I hope they still come out and do it. I really enjoyed working with Chuck. He is a great guy and I highly recommend using this company. Stay away from PermaSeal! I say this because they tried to take advantage of us prior to us contacting this company."

FAQs for radon gas testing projects in Chicago, 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.
