"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."

"Jason was very helpful explaining the testing process, and possible mitigation if our Radon levels were high. Radon testing was setup and conduced quickly and our levels were in acceptable ranges, so no mitigation was required."

"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."

"I couldn't be more pleased with the radon mitigation service John provided. The estimate was accurate-no surprises. He was prompt, efficient and quick- it took just over 2 hours and that's including answering all my questions (and I had a lot of questions!). John's customer service was excellent and the results have so far exceeded my expectations. I am very glad I chose RMR."

Radon Detection and Reduction questions, answered by experts

Yes, many systems include warranties for performance. Confirm terms with your installer.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. 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 preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

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

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.
