Your Austin Area Infinity Replacement Expert
Brett Nielsen
I’m a design consultant with Infinity Replacement by Marvin, and before that I worked as a firefighter and EMT. That experience shapes my work—with integrity, professionalism, and a calm, consultative mindset. I take a low‑pressure approach focused on building trust, listening to homeowner needs, and providing tailored solutions. I believe in educating customers, explaining technical details, and demonstrating value so they can make confident decisions. I’m proud to deliver an exceptional customer experience, and I’m grateful to continue serving homeowners.
Great company to work with. Professional and offered advice. Didn’t try to over sell. Kept me informed throughout the project. The installation was completed in a day and the crew was professional and friendly.

No more leaky windows, painting or repairs—just timeless beauty, views, and energy efficiency
With its high impact resistance, Infinity's Ultrex® fiberglass takes the stress so you don't have to. Unlike vinyl, you won't have to worry about how your Infinity windows and patio doors will hold up over time or against the elements.
While vinyl sash and frame components can shatter, warp, and crack, our Ultrex fiberglass is built tough. It stands up to extreme weather conditions and resists warping and shifting, preventing seal failure and maintaining energy efficiency year after year.
