"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."

"JC Radon Solutions did a great job in the installation of our radon mitigation system. They arrived at the agreed time for both the proposal visit and then for the install work. The work area was kept clean during the install. A great job by a great company. I highly recommend JC Radon Solutions for radon mitigation work. Prior to the mitigation work, radon monitoring recorded average readings of 10. Now the readings are 3.5. Very pleased with the JC Radon Solutions system."

"We were very happy with the crew who worked in our home. Very professional. Prepared the site so we could not tell they had even been in our home. Testing following the job indicated that the radon gas was leaving our home. Our radon level went from 12 to 0."

"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 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 questions, answered by experts

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.
