    Steve, Production Manager, made sure that all parts for our door repair were ordered and received in a reasonable amount of time. Adam was professional, knowledgeable and very neat when performing the repair. We highly recommend Window World, their products and their service.

    Had our windows replaced by window world. Service was great during installation. We had a broken part to the window a few months later and someone came out to fix it promptly and their service was great as well!

    We bought 20 windows several years and finally had a minor issue. They came out promptly and fixed it, no charge. They are wonderful to work with.
