Huge shoutout to our representative Spencer Smith at Champion Windows! He was knowledgeable, patient, and flexible and made the entire process seamless. He helped us finalize the extra details for our outdoor space with ease. We have used Champion Windows in the past and are looking forward to the installation and the final product.

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.
