I was watching the nightly news on tv, one of the segments was about radon gas and at the end of the segment it gave information about how to send off for a free radon test kit which I did. When I received the test kit, I followed the directions and sent the kit off to be analyzed. When the test results came back, the results were high. I did some research on the internet for companies that handled radon problems. The one company that caught my eye was Radon Safety. I filled out the information for a proposal and emailed it back to Radon Safety. I received a call from Amanda, and we set up an install date, and she also told me the name of my installer. On the day of the install, Alejandro the installer was there right on time, and we talked about the best placement for the system, and he answered all of my questions. The installation went well and Alejandro explained how the system worked. Alejandro was a pleasure to work with, and he and his helper did a great job. I was very pleased with the follow up radon test results. I highly recommend Radon Safety to take care of your radon concerns.

Really satisfied with service they provided. Price, communication, professionalism of installers - 5 stars. I couldn't believe they installed membrane in my less than 2 feet high crawl space in one day. They provided test kit for checking radon level after job done. I ordered another one from the company I did tested radon level before. Both those tests showed radon level dropped from 6.5 to 1.4 . Great job! That's even lower than minimum of normal level. Thank you guys.

10/10 recommend! We needed to get a raddon mitigation system installed and when we reached out to shop quotes, they were easy to work with and the turn around time was wonderful. At the time of service, it was quick, and he was very informative. They made the process very easy and stress free! Thank you!

They were prompt, professional and courteous. Alejandro came early and finished promptly. He respected my home and worked to find the best possible location for my radon mitigation system. I highly recommend them.
