"It took less than one hour for the serviceman to replace our old loud radon fan. He was friendly and answered all the questions we had. We highly recommend them."

"I waited a month before getting a test kit I called and was told there was something wrong with the Angies list orders but that I would be receiving a kit soon. It wouldve ben nice if they called me to tell me that though. The test results were quick and on par with other radon test I had done locally."

"Installed radon mitigation system in basement. Pros: 1) reduced overall radon levels by about 75% 2) they did the work in extreme cold temps 3) done in about 4 hours Cons: 1) They arrived late (although they did call to let me know) 2) they did not wear boot covers or put down any floor protector when walking on my carpet 3) they set dirty toolboxes and caulk guns directly on carpet 4) exhaust pipe is too close to roof peak and can be seen from street view of house Overall, good job. I can live with seeing the pipe from the street. I would recommend based on the overall work."

"<p>The inspection went very well.  The inspector returned my calls promptly before scheduling the appointment, he explained how he would perform the work and scheduled us promptly, he was even willing to schedule us on a weekend. He arrived on time and was very friendly and professional. The inspection was very detailed, he visually inspected all relevant areas of the property on both the inside and outside of the building. He visually inspected all possible water entry areas on three levels of the house to identify any water damage or presence of mold. An air quality test was performed using high tech equipment on each level of the home to check for the presence of mold particles in the ar. </p> <p>We received a written report from an accredited lab with results of the air mold inspection within a week after completion of the work. A summary was provided by the inspector including photos and detailed explanations of his findings.  We were very pleased with the quality of the service provided and would definitely use this company again. </p> <br />"

"I was concerned with the other contractors we talked to because they required holes to be drilled in our basement concrete floor as well as pvc pipes being run all over our basement.  But with this system, the suction pipe went through our existing sump cover.  So we ended up with no dusty mess and no ugly pvc pipes on our home exterior because the fan sits in the interior. <br /> <br /> We were extremely satisfied with the solution - the radon levels are very low now - which is important because our kids play in the basement a lot."

"Rick from the Housedoctors was very professional and did an amazing job. He was very thorough and inspected every nook and cranny in the house! What impressed me most was that Rick even noted the minor issues that a majority of home inspectors would ignore. We also received the report quickly and it was extremely comprehensive."

FAQs for radon gas testing projects in Dekalb, 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.
