"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."

"Radon Tec worked with me on a reinspection after mitigation. They understood my time demands and that I was living out of state. They completed task on time and on estimate price. Tech even forwarded invoice/results to the closing to give everyone a chance to review documents before closing. I would give a higher rating if I could."

"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."

"Tom and Josh arrived on the day and time promised. They were both very polite, professional and worked extremely well together. They explained exactly what they were doing and why they were doing it! They installed the radon Mitigation system and went above and beyond expectations. They cleaned up after themselves. After the job was complete, it looks like it has always been here. What more can you ask? I will definitely recommend DC Mitigation for anyone who needs this service!"

"Jim was very professional.  He emailed me and called me right back when I was trying to contact him for pricing/availability.  He came out to the house during the inspection, was early, and setup the equipment.  He told me that he had to turn the heat up to accommodate the readings and to ensure quality results.  Within 2 days he had a report emailed to us - as guaranteed/expected - and we were able to say that the house was at a low level for radon and passed with flying colors. <br />"

"We used Radon Testers for testing in our home in Chicago. I was very pleased with the responsiveness and professionalism of the company. They are also very technology enabled - you can make appointments online, you will receive an auto text when they are on the phone and test results are sent in .pdf form via email. Great stuff! <br />"

FAQs for radon gas testing projects in Lake In The Hills, 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.
