"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."

"The owner, Jerry Stal, provided a competent inspection and assured me that all that my basement needed was a surface treatment. This was inexpensive. He saved me thousands of dollars because the other companies recommended a lot of tear down and other costly actions."

"I have zero complaints about our tech, Jack. He was thorough and communicative! We have a system installed through the roof and he was able to paint the exhaust pipe to match the shingles. The front office wasn't as great. We had to schedule a follow up visit because the initial install wasn't going to work. Unfortunately they never put me on the schedule the second time. So my install day came and went but we didn't hear anything from Swat. I calle the next day and no one knew what I was talking about. Our account manager (Brian) was very apologetic and offered to take some money off our install because of the confusion and the fact that there were no available appointments until August 11th. Luckily they were able to add me to the top of their cancellation list, so we ended up with a system just 3 days later. I appreciate their willingness to make it right with me. I would reccommend them to others looking to have a radon abatement system installed."
