We had an amazing experience with SI Windows. After interviewing 5 or 6 companies, we are so happy with our decision! We’ve already referred several of our neighbors in Rio Verde to them. They took their time to re-design almost all of our window styles to maximize our view! My wife is a realtor and we both understand what a huge improvement this is to our home. -Ron & Nancy, Rio Verde

What Our Customers Say

Impressive. Our installers were on time, diligent and courteous. The product is truly superior and high end. We looked for replacement windows for a long time and I felt let down with the high maintenance of wood and cheapness of vinyl. Aluminum was what I thought was the most sturdy and effective but with the heat transference, that was problematic. Enter GLASS FIBER extrusion.

Tim Shanahan

Process was smooth and the installation met all my expectations. I would not hesitate to recommend this company to anyone replacing windows. Greg took the time to go over materials and I was already skeptical about vinyl frames and I’m sure happy we went with fiberglass!

Mark Ellis

We enjoyed working with Infinity. They were precise on their information and dates for installation. Their installer was prompt, courteous and enjoyable to work with. I highly recommend Infinity from Marvin.
