"This was a radon inspection. Epic responded quickly on a Saturday to my quote request and I never heard from the other 3 businesses. Epic was quick to work with us on the schedule and provided a professional report. They also responded to questions after the report was provided. Would hire them again."

"This was the 3rd time I’ve used Axium (specifically Tim Krapfl) for home inspection. Tim is very thorough, knowledgeable, and professional! I highly recommend. Tim did the home inspection, but the services also included sewer scope and radon testing."

"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."
