They let us know when they were coming and showed up ready to work. They got up on the roof and let us know that there were other things on the roof that needed to come down like an old antenna and some wiring.

They installed our Sonos system, as well as our tv & we had no problems until 2 years later! A few days ago, we had a weird problem with Sonos & called Rick for help.

When I wanted to pay the bill, he said, "Nah, no charge!!" When do you ever find such decent & fair dealings with clients!!! Love these guys!!! You will, too!!
