"Schan did a great job, very professional. He came out to see what the job was before he gave me a quote. I have a huge crawl space which took some time but he stuck with it to finish it in one day. Now I can breathe easier knowing it's taking care of right. I highly recommend Clean Air Radon Systems."

"I highly recommend Midwest Radon Services and I am relieved that the system installed was effective. Price was fair and competitive; all work was thoroughly and patiently explained with no pressure. Work was neatly and expertly finished. Suction under the basement slab was tested by measuring into a hole drilled then patched at the other side of the basement and turned out to be extremely good. The system continues to work extremely well with a sight verifiable U-tube monometer on the exhaust system continually monitoring. In addition, over 18 days since installation, the long term Radon readings, on two different digital testers purchased from Amazon, went way down from a maximum of 4.5, to a range of 0.83 - 0.6 during the time when the furnace was being used which is also a time that Radon readings tend to peak."

"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"I consulted with Radon Doctor about my home. The four foot high basement had 5 pci in a 48 hour test. The first living floor was 1.5 pci in the same test. Radon Doctor advised me to monitor radon levels on the living floor over 6 months during winter season and get back to them for mitigation if needed. They did not take advantage of a single basement reading to insist I install a system that would not affect the living floor levels. These guys are legit."

"I rarely post reviews. Sidad came out a day after I called about our 9.5 radon level to inspect and tell us about the installation route of his mitigation system in our basement. He returned the next morning, installed the system & our 3rd party test report came back at 0.3 which she said was super low. I can not say enough about Clue Radon and his excellent job! And on top of that he is honest and very kind! BTW I first called 3 well known Radon Companies in Lake and Dupage County and they all said I'd be looking at a 2-3 week wait because they are that busy. Call Clue Radon:)"

Radon Detection and Reduction questions, answered by experts

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

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.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.
