"Radon test is done and info was useful. Now we are planning on an update of old radon system."

"We hired Custom Radon Mitigation to handle our Radon problem. They were awesome, we had zero problems. Great work!"

"Aarmond installed a radon abatement system in my house. He brought my radon level from 14 pCi/L to less than 4. He is very professional and I heartily recommend his company."

"Steve did a great job and provided several options for our Radon mitigation. He did a great job and the Radon levels quickly dropped to well below minimum standard."

"They showed up on time and finished within 2 hours completing radon mitigation system."

"I recently used #1 Radon to fix my existing radon mitigation system. I called and Jesse Fuller came to look at system same-day. He had it repaired the same week. He was professional and made me feel comfortable with work and costs to replace the existing fan. I highly recommend #1 Radon and Jesse Fuller."

"Our radon system was making an unusual humming noise and it was driving me crazy! I found The Radon Guy here on Angi. Shortly after posting my request, Giovanni contacted me and and within a couple of hours I had the answers I needed and a testing system set up to measure levels since they hadn’t been tested in 2 years. He explained the problem and because the fan is under warranty, will be having a new one installed soon. I appreciated Giovanni’s quick response, professional demeanor, fair pricing, and extensive knowledge. Highly recommend!!!"

"Called to ask about getting someone to come check on our radon system, which had stop working several months earlier. The person I spoke with, was friendly and very helpful. She was able to answer a few questions over the phone. She was also able to schedule someone to come out within the week. I was impressed that I received both an e-mail and phone appointment confirmation, the day before the technician was suppose to arrive. The technician showed up right on time, was professional and was able to diagnose the problem quickly. We needed a new fan for the system. Less than 30 minutes later, he was done and everything looks great. He left a radon testing kit that we will use in a week to make sure everything is working. Great experience and would definitely use them again in the future if needed."

"Very professional, courteous, and knowledgeable. They didn't oversell me and corrected the issues I was having with persistence and creativity. They got things up and running again with the least amount of work necessary. I highly recommend Rocky Mountain Radon."

"John did a great job. Our radon went down way more than I expected, to almost nothing. There were a couple of blips along the way, and they did everything to fix things with no trouble to me at all. I would highly recommend."
