Advanced Exteriors’ windows division grew out of our work as a contractor who specialized in insurance claims. In this capacity, our team of experienced professionals has had the opportunity to work with and/or replace dozens of different types and brands of windows, and we know firsthand which windows are top performers and which windows fall short of their hype. At Advanced Exteriors, we want everyone to enjoy the exceptional performance our replacement windows have to offer.

Whether you are considering vinyl or wood replacement windows, we have carefully selected the products we sell based on their manufacturer’s reputation, warranty and the overall performance of the window. For instance, whereas most replacement windows have standard glass, we only sell windows with glass that’s twice as thick.

“You all went above and beyond to help me out with my situation. I couldn’t be happier with the quality of work and professionalism of the staff. Thank you.”— Martha Kessler

Additionally, all windows that are offered by Advanced Exteriors have a double low E coating, as compared to the competition’s single coating standard. And unlike our competitors, whose windows feature a smaller ½” counter balance, our windows feature a more substantial ¾” counter balance.

The list goes on and on, and best of all, these features come standard on our windows, meaning we probably won’t come in with the lowest initial quote, but once you add in all the extra bells and whistles, we’ll likely provide you with the most bang for your buck…and eliminate a lot of headaches and frustration along the way.


Beyond offering the very best quality replacement window at a great value, we also pride ourselves on being trustworthy and fair. Unlike some of the big box stores, who are most concerned with the volume of windows they sell, we are dedicated professionals who believe in sincere customer satisfaction. Beginning with the way Advanced Exteriors provides you with honest and informative evaluations of your existing windows all the way to superior installation craftsmanship, you’ll notice a genuine difference in the way we treat our customers.
