"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."
