"Veteran Radon installed a radon mitigation system In our home on 2/19/26. They did a great job, and we recommend them highly! Jason came to our home to look at the situation so he could prepare an estimate. He was friendly, courteous, and happy to answer our questions. Our system was installed by Ken, who was thoughtful, conscientious and efficient. He gladly worked with us to locate the outlet of the system where it would have the least impact on our outdoor space. The work took only about half a day, minimizing disruption to our lives. His workmanship was excellent. The completed system looks very neat and well constructed. Everything fits beautifully. Prior to the installation, we had tests showing radon levels of 20.4 pCi/L and 25.9 pCi/L. Post-installation testing showed that our radon level was reduced to 0.7 pCi/L, well below the 4.0 pCi/L that the State considers acceptable."

"Highly recommended. Gage did an initial checkout and provided an estimate and details so I could get the installation approved by my HOA. Then he completed the job himself, very professional installation and careful cleanup. And the system is effective, dropping my radon readings from over 10 to below 2 overnight. "

"All Colorado Radon Mitigation, Inc. is an incredible company to work with. They perform quality work, and they are truly friendly and professional. The system that they installed was straightforward, but the work was top-notch. Highly recommend!"

"Buyer Beware!!! Once the installation is complete, you're on your own. I own a digital radon detection device. It's been over a month since the installation and the radon levels are above recommended levels (4/20/23 4.4, 4/21/23 5.2, 4/22/23 4.2, 4/28/23 6.4). I didn't monitor it every day but today it's at 4.3. When I contacted John the owner on 4/19/23, he suggested two options. 1. Install a larger fan for $150 which he said may or may not work and 2. Call some company to come out to run a scope to see if there is a blockage. He couldn't suggest a company because he didn't know any. The one option he didn't offer which I suggested, was to have one of his technicians come out to take a look at it. Needless to say I am not a happy customer. I paid $1,300 for something that doesn't work with no recourse. I will be contacting the BBB though."

"Tricia and John were great, very communicative, and the entire process was easy, no issues. Highly recommended!"
