"Bill was very professional, friendly, and patient with our questions from start to end. He explained the installation in detail along with providing pictures of what to expect. Within 24 hours of installation, Airthings Radon monitor reported a significant radon level drop. After one week, the Radon average has gone from 8.6 to 0.6 pCi/L. Thank you, Bill and Jose."

"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."

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."

Radon Detection and Reduction FAQs, answered by experts

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

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.
