"I don?t know that I would trust these guys. I received a quote to replace my pump. Agreed to do everything they suggested. The day they did the work, everything went smoothly. Unfortunately the outcome wasn?t what I was hoping for - increased water production on a poor production well, but that?s not their fault. Here?s where you shouldn?t trust them. Right as the job was finished, a fourth guy showed up. He sorta fumbled around and did nothing, apparently he was their solar guy. When they were ?finished? two of the workers demanded payment, one of which was pretty rude about it. It felt odd considering the job wasn?t completed, they were supposed to come back the next day and install a bracket to support the water line. They left all my old well pump, pipe, and wires which is what I wanted. They took the pump controller that was less than a year old. Then I get the bill and it?s $600 more than I agreed to with no explanation, other than the fumbling solar guy said it took 4 guys. "
