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."
