We are having 20 windows replaced. Josh Milidor was the perfect example of a sales person. He Polite. Prompt. Not “pushy” – let us make our own decisions in our own time without applying pressure selling techniques. He thoroughly answered any questions we had. We are hoping the rest of this experience is just as good.
