Create the home you deserve.

The people that make up the Marvin Family of Brands are dedicated to enriching the places where we live and work.  What began as a family company built on an old-fashioned code of honesty, hard work, and service to their neighbors is now one of the world’s premier window and door companies.  Our two unique brands—Marvin and Integrity—and each brand’s unique offerings of customization and performance, we can provide a solution to any project.  For everything from new construction to remodeling and replacements, to commercial building and even historical restorations, we never take shortcuts, and we always adhere to the highest possible standards and the highest levels of service.  We stand behind every one of our products, every step of the way.

We make it our priority to be a partner to our customers through every step of the process, and go above and beyond what is expected.  That includes making sure our products continue to live up to our high standards every single day.

Custom Window Supply provides guidance on design ideas or options and operational features in clear, easy-to understand language.  We have multiple resources to help you visualize the best windows and doors for your home before purchase.  And for as long as you own your home, feel confident knowing your Marvin windows and doors are covered under a Full Lifetime Warranty.
