At Keystone Window of Pennsylvania, we are committed to buying all of our products from Manufacturers that have been in business for a long time whenever possible. This ensures the warranty given at the time of sale, really has meaning. Most companies offer a LifeTime Warranty.

Our Vinyl Windows and Doors always carry a LifeTime/Transferable Warranty covering the glass (seal only), vinyl, and all hardware. Basically, everything is covered with no questions asked. If a Warranty issue happens, you simply call our office and we order whatever is needed and come out and take care of it as quickly as possible.

That is the Advantage of buying from a locally based company that is all about customer satisfaction.
