Welcome to Key Exteriors, Inc., Fort Wayne's leading residential replacement contractor. Bill Kesterke started Key Exteriors in 2003 for one reason: Integrity. Having worked in the business for a large national company with little control over the finished product, we have determined to start a company that focused on providing customers with the highest quality products, installation and service after the sale, in the industry. Our goal was not to be the cheapest nor to be the most expensive, but simply to be the best value bar none. We focus on giving the most convenient terms possible at the best value possible.
