"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."

"Mat is the inspector realtors hate... tongue-in-cheek. He is extremely knowledgeable, has great attention to detail, and is very honest. If there is something wrong with the property, you better believe he's going to find it. He takes the time and does a thorough job. I highly recommend him!"

"Tim was on time and finished early. Nice, neat install. I can't be absolutely sure how accurate my radon detector is but before the install the highest short- term reading I saw was 7.94. After the install I haven't gone over 2 and usually is 1.5 or lower."

"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!"

"A++ service. Mike performed an excellent job testing a house we are in the process of purchasing in addition to the Radon testing. We found him to be personable, straight forward, detailed, honest and informative. Each area of concern, Mike provided clear details for the rating given which included pictures with arrows pointing to the exact location. Overall process went smoothly. Would gladly hire again in the future and/or provide as a reference."

"Ron was very responsive and was able to get the equipment delivered and installed with short notice. He engaged us in some conversation and clearly loves what he does. His associate returned 48 hours later to retrieve the machines and Ron called us the following day for payment and to provide the results. Our home tested in the 4-6 picocurie range which is above the action level of 4. Ron emailed detail results which showed the measurement by hour and by location, information about radon, and information about remediation (including referrals to local providers). He also included information regarding the legal aspects of radon as it relates to testers and remediators. Definitely recommended. This guy lives to do radon testing!"

FAQs for radon gas testing projects in Algonquin, 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.
