"Radon Shield was hired after I got a higher then expected reading for radon in by home when selling it. Benedict shared a lot of great advice about radon gas in the home, he was able to schedule the install in a very fast time frame which was extremely helpful because I was selling my home. The quality of work was outstanding and he did a great job explaining thing to me and by wife. He also did a great job cleaning up after the install. I would hire Radon Shield in the future in needed."

"Radon Shield did a wonderful job with radon remediation in our basement - our level was below 4.0 but we wanted it even lower. Benedict and his team worked efficiently and carefully, and our radon level is now 0.3 upon repeat testing after fan installation. They are professional and reliable - highly recommend their services."

"I could not be happier with this company. They did the work right away, even working on the weekends. They were very knowledgeable about what needed to be done and how to get the debris tested they have been very responsive. They have continued to be helpful to me in dealing with the company that left the silica dust in my home. You will not be disappointed if you use this company. I have never seen a company that is so attentive to your needs.
