"Finding a reliable contractor is tough these days, but I got lucky hiring Chris. He and his son arrived on time, replaced my electric hot water tank, fixed a leaking guest bathroom sink, and cleaned up afterwards. Chris is a true professional with a great attitude excellent work at a fair price. I highly recommend him."

"We had a standard water tank that failed on Friday July 1. I reached out to Matt with water issues from the tank, but more importantly- to find out options for a replacement. He convinced me to go with a popular and reliable tankless system. I called him at 7:40am, the parts were delivered at 11am and Matt came by at 1pm. By 3:30pm, our new system was operational. Going into a holiday weekend - that was fantastic service!"
