"I am an out of state seller of a property in Colorado Springs that during a routine radon testing tested slightly high. I was referred to Axium by my realtor who highly recommended them. I contacted them and made all the arangements by phone / on-line. It was very easy. They provided a very competitive bid, were able to do the work in very short order, no surprises. Converted a passive radon system to an active radon mitigation system."

"Bought a house and had a Radon Test done. It came back higher than the recommended EPA levels (I trust and believe in the EPA actually). Got a number of estimates and reviewed some companies. I went with SWAT Environmental as they could schedule weekends. I believe his name was Robert, he showed up on time and completed faster than expected. He answered all of my questions and was open and honest about everything. He was respectful of the property interior and exterior. Overall a great experience and I would recommend SWAT if you need Radon Mitigation."
