After completing my own Radon testing and discovering we had a problem initiating from our crawlspace and affecting the living area of our one-story house, I contacted Clayton at 307 Environmental for mitigation solutions. I had done my own research into Radon issues, and felt prepared to ask the right questions. Clayton developed a solution that was better, and cost less, than I had read about on the internet. His mitigation system immediately resolved the Radon problem by lowering the levels significantly less than my test results, and within the recommended public health standards (EPA). Clayton was professional and informative, explaining how and why all aspects of the job, and always left his work area clean. We are extremely happy with our new Radon mitigation system, and would strongly recommend 307 Environmental to others. read more
