"Radon exhaust fan was making noise. I did some research and ascertained bearings were failing in the fan. I arranged a good time to get it replaced, he showed up and had it replaced in about 20 minutes. I did give him the model number of the fan so he knew for sure what I needed. Quick and easy."

"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."

"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."

"I couldn't be more pleased with the radon mitigation service John provided. The estimate was accurate-no surprises. He was prompt, efficient and quick- it took just over 2 hours and that's including answering all my questions (and I had a lot of questions!). John's customer service was excellent and the results have so far exceeded my expectations. I am very glad I chose RMR."

"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."

"HOLLY THE OFFICE MANAGER IS GREAT TO WORK WITH. I HAD RECEIVED AN ESTIMATE FOR RADON MITIGATION BACK IN MARCH AND WHEN I CALLED IN DECEMBER, SHE IMMEDIATELY SAID THE QUOTE WAS STILL GOOD. JASON ADAMS DID THE INSTALL AND DID A GREAT JOB. HE WAS VERY CAREFUL AND DID VERY EXACTING WORK. I WOULD HIGHLY RECOMMEND RADON SAFETY LLC. DAVE MAHAN, LAFAYETTE, CO."
