I've tried four different clinics in the Denver metro area over the past couple years and this one actually listens. The approach here is less about rushing you through some cookie-cutter protocol and more about figuring out what works for your actual life. I appreciated how much time was spent on the initial consultation. The space itself is small but set up efficiently. What really makes the difference compared to the other places is how the treatment plan gets adjusted based on what's happening week to week instead of just sticking to some rigid schedule. The follow-up appointments feel like actual conversations instead of quick check-ins. I noticed the intake forms were pretty thorough, which I guess is why everything felt so tailored. Down about eleven pounds since starting and the energy shift has been noticeable.

We recently had a radon mitigation system installed. The team was professional, courteous and performed quality work. Sean was great throughout the entire process. We’re very happy with Sean and Absolute Radon Safety and would highly recommend them. Thanks!

Miguel was a real pro. Did quality work, yet took time to answer all my questions that the HOA is going to want to know.

Amazing service. We chose this business because they took the time to come and talk to us with an in person quote, followed with zero pressure while they waited for us to decide which company to go with. Once we chose them we were quickly put on the calendar. The installer was great and walked us through everything he did.

Of the estimates I received, Absolute was the most thorough in assessing my needs and how to retrofit given the pre-existing construction. The other companies gave quotes after a quick look or even a phone consultation, which may or may not have solved the problem. Absolute was very ethical, honest, and thorough, and the actual workmanship was top-notch. Very fast and pleasant in responding to questions. Highly recommended.

I had a great experience with Absolute Radon Safety and would highly recommend them. Sarah, who helped schedule my service appointment, was incredibly friendly and accommodating. My power happened to go out around the time of my appointment, and she was very flexible in working around the situation. Before scheduling the service call, she also walked me through a few troubleshooting steps to see if I could resolve the issue myself and avoid the cost of a visit. I really appreciated that level of honesty and customer service. Miguel, the technician who came out, was outstanding. He was knowledgeable, professional, and easy to work with. Although the primary issue turned out to be electrical, he took the time to help me with a few other minor issues related to my radon mitigation system and made sure everything was working properly before he left. It's refreshing to work with a company that is responsive, honest, and focused on helping customers rather than simply selling a service. I would absolutely use Absolute Radon Safety again for any future radon mitigation needs.
