"Jason was extremely helpful in installing our radon mitigation system. He even went above and beyond in helping us with other issues our home had. Definitely recommend him and Veteran Radon!"

"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."

"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."

"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."

"Painless and efficient installation of radon mitigation system. A real pro and highly recommended!"
