"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."

"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."
