Hello, My name is Alex Velez. My wife and I own a home in Maple Leafthat needed new vinyl double-pained windows. Through a strong recommendation from a neighbor, we chose Keystone Windows and Doors. We were very pleased with their courtesy, professionalism and craftmanship. New efficient windows are a necessity if you decide to sell your house in a tough buyers market, or cut down on your heating bill or eliminate outdoor noise. I can see why my neighbor picked Keystone, and would recommend them highly to everyone.
