"The installer (Davis) arrived on time, installed the system in about two hours, and showed me everything I needed to know about the system. The “before”and “after” test results were right in line with my own test measurements, which I took with a portable radon detector. The radon level dropped to a safe level after the system was installed, and that level has been maintained since it was installed in July of 2020, about 10 months ago. Overall, I was extremely pleased with A & R and I highly recommend them for radon mitigation work."

"I highly recommend Apex Radon Solutions. From getting the estimate to getting the work done, everything was just outstanding. Marco and his crew of 3 men showed up early and were all knowledgeable and extremely skilled. I had to install a radon fan and put in piping and electrical. They measured the piping with care and accuracy and did an excellent job with the installation. Iâ m truly impressed with the professionalism and quality of the work. They were also very reasonable with their prices. Thank you Apex for such great work."
