President — Infinity from Marvin
A local independent retail partner will provide a complete consultation to determine your specific needs — including climate considerations and other factors. They will answer all your questions and provide a detailed, custom project quote based on your specifications.
A measure technician will review your order, measure your openings and verify your installation needs. Your windows will then be built to your exact needs and specifications.
Installation professionals will remove and dispose of your old windows, and replace them with your custom Infinity windows.
From our Limited Lifetime Warranty to unparalleled customer service, we go above and beyond to ensure your windows provide a lifetime of optimal performance.
From unmatched craftsmanship to our warranty that protects your windows for as long as you own your home, we design everything to exceed your expectations and give you peace of mind.
Marvin is proud to have provided customers across the U.S. with quality windows and doors for over 100 years. But we’re not content to rest upon our heritage. We created Infinity from Marvin to provide homeowners with a new way to shop for replacement windows — centered on providing ease, confidence and a quality experience every step of the way.
