Very pleased with Rocky Mountain Radon Mitigation! Ian came out right away to give us an estimate, and Alec was great with handling the installation process! They have a lifetime warranty on their work. The radon fan comes with a 7 years warranty. Very pleased!

I interviewed four companies, and picked Rocky Mountain. Ian was super helpful and very clear on what they provided. Installation was great, Arthur knew exactly what he was doing. I hired a professional company to get the new radon report, and it was less than 2. Way below the EPA level. Success!

We had a radon mitigation system installed. After the initial installation, we ran into an issue, and I reached out to Ian, whom I believe is the owner. He personally came out and fixed the issue and his communication was phenomenal. I can’t recommend them enough!
