Chris showed up at our home yesterday on time. He even called to see if he could show up a little early. He went through the whole sales pitch and then got right to business. He answered all of our questions and explained things very well. We appreciate Chris as he was very professional and personable and was not a pushy salesperson.

Our installation crew, Jason, Jakob, Chris, and Dallen were awesome. Pleasant, courteous and made sure I understood what they were doing. They also cleaned up as they were going along. And all seemed to know what they were doing.
