"RADON SYSTEM WAS NOT WORKING. (Installed by another company years ago). The phone contact was pleasant and efficient. The Technician came on the agreed day and the agreed time: he explained what was wrong, explained the options, then repaired the system so it is working better than it did when first installed."

"I had done two separate radon tests and knew the level was high. Bill came to evaluate where to place the system. He gave me a rough cost and time it would take for the install. He was able to schedule the install within a week. He arrived when scheduled. They did a very thorough job and cleaned up well after the install. It was hard to tell they were here. Very professional. The only knock I would have is that because they are quite busy, it is difficult to get an initial visit as Bill does the evaluation himself. You may have to call a few times and it was a challenge to pin down.
