"Our radon specialist, Tim Milledge, was terrific. Communication was excellent, he arrived on time, was professional, courteous and experienced. He was able to run the pipe line and place the other equipment in a way to be unobtrusive and did nothing to detract from the aesthetics of our property. He explained post procedures and cleaned up after himself, unusual these days with service providers, and completed the installation quickly and efficiently. We would highly recommend SWAT and, in particular Tim."

"The first contact was answered promptly and an estimate meeting was arranged. A few days later the estimate and shingle color samples were delivered by mail. No better estimates came. In fact, most companies contacted failed to respond at all. When I accepted the offer, we talked again to schedule the job. He estimated the job would start on July 16, and it did.
They started early on the first day, worked nearly until dark, and came back to finish the next day. They were done by mid-afternoon.Apart from the roof being all new, I could hardly tell they had been there. No mess, no mashed plantings, no shingle fragments or nails lying about. Still waiting for a rain to test it, but it looks great."
