The Dangers of Radon

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% of Illinois homes tested were above the EPA action level (4.0 pCi/L)*

*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 Mitigation Works

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

What Neighbors Say

★★★★★

“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.”

Steve Autor
★★★★★

“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.”

Bao Bui
★★★★★

“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!”

FAQ

Radon Questions, Answered

Do you offer radon testing?
We do not offer radon testing. We install and service radon mitigation systems. For a test, use a licensed Illinois radon measurement professional or a home test kit, then send us your result for a free quote.
How much does a radon mitigation system cost?
Most residential radon mitigation systems run $1,450–$2,500, depending on your foundation, the layout of your home, and where the system routes. We give a free, no-obligation estimate up front, no surprises. See what affects the price
How long does installation take?
Most systems are installed in about half a day, and you can stay home while we work. It can take a little longer for larger homes, bigger crawlspaces, or older homes that need multiple suction points or more complicated work, but most are still done within one day.
Will the system really lower my radon?
Yes, and we guarantee it. A properly designed sub-slab depressurization system routinely brings homes from double-digit radon levels down below the EPA action level of 4.0 pCi/L. We recommend a follow-up test to confirm the result in writing, and if it isn’t below 4.0, we’ll come back and make it right.
Are you licensed and insured?
Absolutely. We’re a Licensed Radon Mitigation Specialist through the Illinois Emergency Management Agency (IEMA), license #RNM2020203, and fully insured. Radon mitigation in Illinois must be performed by a licensed professional.
My fan stopped working / my system is loud. Can you help?
Yes. We install, replace, and repair radon fans of every brand, even systems we didn’t install. A humming, rattling, or silent fan usually means it’s time for a replacement. See our radon fan service
