"Gage from Custom Radon Mitigation Systems did an amazing job installing my radon mitigation system. Upon arrival, he determined the best location in my mechanical room where to install the system, provided a timeframe for completion, kept me apprised of where he was in the process and informed me on how the system ran. Before the installation, my radon levels in my finished basement were routinely well above 4.0 pCi/L with a high of 14+ pCi/L. Since installation and checking for a few days, my radon level is often below 1.0 pCi/L and no more than 1.5 pCi/L. I'm very pleased with the system and Gage's professionalism. I sleep better at night knowing that my RadonEye device won't be setting off an alarm 2-3 times a day now. If you're considering a radon gas abatement system, I highly recommend Gage and Custom Radon Mitigation Solutions."

"All Colorado Radon tackled a particularly difficult radon mitigation that other companies refused to mitigate. They were very thorough and knowledgeable. Most of all, they were successful in reducing radon levels to well below government standards. We would use them again."

Radon Detection and Reduction questions, answered by experts

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

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.

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.

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.
