"After my basement test come back with significantly elevated radon, I contacted radon abatement services at the recommendation of a neighbor. A day and a half later, they were on site. While performing the initial walk through, the experienced and thoughtful professionals adapted their plan to utilize my sump pump. This was an effective strategy as it addressed the main source of radon and concealed the system in completely unfinished space. I just received my post mitigation radon results, and the system is working phenomenally. To sum it up, I was blown away by the responsiveness, thoughtfulness, and reasonableness and can't say enough positive things about this company. I don't ever post reviews, but in this circumstance I absolutely had to."

"Did a great job! Very professional! Before installation, my radon level was at 4. One week after installation, it has gone down to 0.3. While their prices are a bit higher than others, they guarantee their work and parts, which no one else seemed to do. I would highly recommend!"

"The service was good. He showed up on time and did the test. The only problem I had was that he is not a full service, he only checks for asbestos and does not remove.The test took longer than I was told, but I don't think he had a choice. Overall he was ok, just not a perfect match for my needs."
