Radon Is the #1 Cause of
Lung Cancer in Non-Smokers
You can’t see it, smell it, or taste it, but radon is a radioactive gas that seeps up from the soil into homes across Central Illinois. The EPA and U.S. Surgeon General link it to about 21,000 lung-cancer deaths every year. The good news: it’s completely fixable.
*Nearly 40 percent of Illinois homes tested were above the action level, per the Illinois Emergency Management Agency (IEMA), January 2015. See why Illinois radon levels are so high

How Radon Gets In,
and How We Get It Out
Radon seeps up from the soil and gets trapped under your foundation. A David Smith Radon Remedies system catches it first, before it ever reaches the air you breathe.
- A sealed suction point under your slab captures soil gas at the source
- A quiet, continuous radon fan vents it safely above your roofline
- We seal the cracks and gaps radon was using to sneak in
- Guaranteed to bring your radon below 4.0 pCi/L, or we come back and make it right

“My basement tested 9.6 instead of below 4.0 with the testing device I bought, so I called different vendors. Their website is very well done and describes accurately how they work. We made an appointment and four workers showed up after lunch at our home in Danville, IL and went to work. They finished by 4:30pm and were on their way. Very impressed with this company. Highly recommend them.”
“Great experience, everyone we talked to was a pleasure to work with. The install looks great, and took only a few hours. Everyone was very friendly and helpful. I’ll also note that when they noticed I was wearing a mask indoors, they offered to put one on as well, so they are really attentive to their customers needs/comfort. Highly recommend!”
“David Smith Radon rightfully deserves a 5-star rating. They installed my radon mitigation system a year ago. The price they quoted me was quite competitive. Then, when the machine started acting up two weeks ago, I called them and they told me the unit was still under warranty. Within a week they sent out a crew to replace the malfunctioning unit with a new, quiet unit. Their staff are responsive, and their field crew are a super-friendly and professional bunch. I highly recommend this business.”
“We chose David Smith Radon to install our mitigation system due to the wonderful reviews and liked that it was a small family run business. They did NOT disappoint. They were wonderful from beginning to end. They showed up early, were professional, courteous, explained everything in detail before, during and after the job. Completed the job faster than expected! They cleaned up and went above and beyond to leave everything even cleaner than it was to begin with. Would highly recommend them for mitigation!”
“On time, under budget, very professional.”
“Excellent customer service, they made the whole process easy.”
