"Jason was very helpful explaining the testing process, and possible mitigation if our Radon levels were high. Radon testing was setup and conduced quickly and our levels were in acceptable ranges, so no mitigation was required."

"The company rep was knowledgeable and hard-working, he even worked with me to get around some technical issues before he started the install. I do wish there would have been a follow up and more education with the “how-to” of the test that I had to set up and send in to ensure that the unit is working properly. All in all, I would recommend Affordable Radon Services for radon mitigation installation."

"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."

"All Colorado Radon tackled a particularly difficult radon mitigation that other companies refused to mitigate. They were very thorough and knowledgeable. Most of all, they were successful in reducing radon levels to well below government standards. We would use them again."

"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."

"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."
