Custom Radon Mitigation Solutions

Gave access to house, sent a picture where I wanted it. Did a great job, aesthetically and functionally. Cleaned up after himself, radon mitigated to acceptable levels.

Gage was efficient, friendly, and knowledgeable. I had full confidence that he not only knew what he was doing, but was going to be communicative along the way. I have nothing but good things to say and will absolutely recommend his services to anyone needing radon mitigation!

Fast, professional and friendly Gage and custom radon were a joy to work with and reasonably priced too. I can't recommend custom radon and him enough

Gage was able to beat the price of 4 other quotes, provide next day service, and was absolutely zero hassle. Highly recommend.

Extremely professional service nice dude gave me an amazing quote on a really complex job, and proceeded to get it done in a timely fashion. Highly recommend!

I had a reading on my meter of more than 5. One guy told me to turn the fan off and close the window then the reading would go down. Instead, it went up to 13+! Gage from Custom Radon, looked at that, gave me the best estimate I received, did the work, and within 48 hours my reading was less than 3; it is now less than 1 at 0.4! Gage was quick and efficient, did a wonderful job, installation looks good, he explained everything to me understandably. I highly recommend Custom Radon.

I had no idea how serious radon could be until a home inspection flagged high levels in our basement. Custom Radon Denver responded to my online inquiry within an hour, scheduled an on-site test the very next day, and clearly explained every reading in terms even I could understand. What really impressed me was their transparency: Gage walked me through the mitigation options, showed photos of past installs, and gave a firm quote on the spot—no upsells, no scare tactics. The crew arrived on time, laid down drop cloths (my hardwood floors stayed spotless), and finished the entire system in just under four hours. Two weeks later, the post-install test dropped our radon levels from 8.9 pCi/L to 0.5. I can finally let the kids play downstairs without worrying about long-term health risks. Professional, punctual, and priced exactly as quoted—Custom Radon Denver turned a stressful situation into an easy win. Highly recommend!

Gage was fantastic to work with. He was knowledgeable, articulate and eager to clarify any questions I had. Our levels dropped from 12.4 to 0.7. It is always great to work with a contractor who you feel you can trust with your home. I recommend Custom Radon to anyone looking for Radon Mitigation.

Professional and efficient.

Custom Radon was fantastic! Gage got off to a great start by showing up early. He answered all of my questions and seemed very knowledgeable in the field of radon mitigation. His workmanship looks great and very well done. I would recommend Custom Radon to anyone who needs mitigation work!

Did a great job!!

They have done numerous systems for me. More than 10. Great communication and very good work. I highly recommend them.

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.

Gage arrived on time and accomplished the job in less than 6 hours-very efficient! Very polite and communication prior was great-answered all my questions! I felt I got a competitive price, plus I liked his guarantee of satisfaction for his work!
