The following test showed significant decrease at the radon level on the property. I am very happy that I hired this company and recommend for your needs."

"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."

"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!!!"

"BIG shout out to North Point Radon! We had to re-do some radon mitigation on the house so we could start working on framing in the basement and they came in and did an incredible job. The pressure from the pump (or however you say it) went up from 1.1 to 1.25, so they filled in a bunch of spaces that weren't sealed up properly and cleaned everything up so our contractor can start framing. No big chunks of puffy foam - everything is sealed cleanly and nice and tight now (obvious from the reading on the pressure). Fast, affordable, effective, and we retested the basement and it came at less than 1%. Seriously good people. I would call them if you need any radon stuff (testing, mitigation, etc.) taken care of."

"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."
