"MaGen did an amazing job testing and abating our radon issue, which we weren't even aware of. Maryan's process was easy to follow, he performed work that was even beyond the agreed process (like making necessary fixes to our crawl space), and ensured that the radon system was working well. We went from having the meter read over 10 (pre-work) to under 1. If you're looking for someone that can handle your radon needs, get MaGen to do it ASAP!"

"All of the Radon Be Gone staff I dealt with were very professional. They designed the system so it vents in a back corner of the house and is barely visible. The staff delivered the external vent pipes several days in advance of the installation so I could paint them to match the exterior of my home. They were timely, polite and very competent at their work. The radon readings in my home were reduced to a very low and safe level."

"The installation of radon system was good. They were on time and very nice and cleaned up well afterward but have not been able to get a hold of the company since then to schedule retest. The phone number indicates that voice mail is full and have texted the number with no response and have also emailed them."
