"He was extremely professional, knowledgeable, and honest. After the visual inspection, he said we didn't need further testing which saved us a lot of money. He provided a thorough explanation for all of my questions and concerns. He also checked all the areas I was concerned with which included some cutting and removing of quarter round.

Central Illinois Radon Mitigation has been in business for over 10 years. We specialize in radon gas removal. We have a team who have designed and installed hundreds of radon mitigation systems with great results. We offer free estimates and guarantee our results!

"I am selling my house and the radon test came back high. I got quotes from several vendors and Central Illinois Radon Mitigation was several hundred dollars lower than their closest competitor. They offer the same 5-year transferable warranty and are licensed, so it was an easy call who to go with. From quote to completion it took less than two weeks to get the system installed. David and the other installer were very attentive to cleanliness, using drop cloths throughout the house and cleaning up the work area when they were done. My only complaint is that they disposed of the gravel they removed from under the house in my backyard and I didn't find it until later."

"Jon at Finest Home Inspection was great. He walked us through the inspection and his findings on site as well as answered our specific questions about the house. Our inspection report was provided the same day and the radon test results were provided as soon as they were available. He let us know what he wasn't able to check because there were tenants living in the house. He gave us his honest opinion on the house when we asked him. It can be difficult to assess the thoroughness of a home inspection, but now that we've been living in our home for a while, I am confident our home inspection was thorough. We haven't run into any issues that were not addressed in the home inspection. I would recommend Finest Home Inspection."

Radon Detection and Reduction questions, answered by experts

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don’t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:

  • Shortness of breath

  • Cough

  • Tightness in the chest

  • Difficulty swallowing

  • Hoarseness

Costs for radon detection services typically range from $150 to $250, depending on the testing method and whether a professional assessment is required.

Through air sampling devices and surface swabs in key areas of concern.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed.
