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!

I needed radon mitigation and did my due diligence to find the best company. Ian responded first and beat the 2 other companies in price, scope of service provided, and availability to install. He was on time with the free estimate we scheduled, and subsequent installation. I was so impressed, I have referred Ian to others.
