Casement windows are hinged on the left or right side of the window, and open by swinging out from your home.They feature a smooth cranking system for easy opening and closing.

I had Mr. Li (owner-Crystal Exteriors) install two exterior doors and one window. He was extremely reliable; both Mr. Li and his installers showed up precisely when they said they would. The workmanship was excellent, and they cleaned up well when they finished. I do not hesitate to recommend them."
