From beginning to end, a professional operation! Ken spent the time talking to me about my options, so I know I made the right decision on product choice. Kryz is a craftsman who not only did an excellent job, but clearly has a great deal of pride in work that has his name on it. He had to move an A/C vent and electrical in the ceiling, and the final result looks like it had been part of the original construction, not a retrofit! I love the skylight and would highly recommend The Skylight Guy!
