I appreciated how meticulous they were. It shows in the final product: the windows and sliding doors look great. They communicated well about schedule. My only complaint was the cleanup outside left something to be desired. Much of the small debris can't be helped, but there was plenty of larger debris (<2 inches) left on the ground from demolition of the old windows. My advice would be to check that before letting them go on the last day.
