The windows are wonderful. WE got the aluminum windows because of their strenght (Houston hurricanes) and they come in several colors for not extra charge and they have slimmer borders. WE're delighted and slept with just the screens between us and the birds last night-- the first time in a long time. The best part was the installation. You don't need to supervise, to wonder if they'll do the best job possible. They treated our home as if it were their own. Already two neighbors are planning to get windows from theim, and we ordered bec ause 3 neighbors before us were raving about them.
