We're incredibly thankful for everything you do and can't wait to see what's next. Congratulations, Leandra!

We love how these new Infinity by Marvin windows transformed the Standard family's home. By opening up the glass area of their windows, they can now enjoy their beautiful landscaping from the comfort of home.

Thank you to the Standard family for trusting Mainstream with your home!

Rolling out the welcome mat... literally!

Our new showroom rug is officially in place, and it's one more thing we're excited about in our new Bettendorf space. A big thank you to 1Corp Apparel for helping us create a welcoming entrance for our customers, friends, and community. We love how it turned out and can't wait to welcome you in!

After ➡️ Before

One of our favorite things about Infinity by Marvin is the ability to customize the interior with EverWood.

For this Davenport home, the stained interior finish perfectly complements the home's style, giving the look of beautifully stained wood without the maintenance of traditional wood windows. We love how this one turned out!

If you're fighting with your patio door every time you use it, it might be time for an upgrade.

Infinity by Marvin sliding patio doors are built for smooth operation, with a top-hung screen that glides easily and stays free from dirt and debris that often cause traditional screens to stick.

We'd love to show you one in person! Stop by our showroom at 915 Middle Road in Bettendorf.

Huge thank you to Vision Haus for capturing the space and helping bring our vision to life.

Want to see it for yourself? Stop in and take a tour! We’d love to show you around and let you experience our Infinity by Marvin products in person.

Today we remember and honor the brave men and women who served and sacrificed for our country. 🇺🇸

Our offices will be closed today as we take time to reflect. Wishing everyone a safe Memorial Day.

Your home deserves more than a standard installation, and that’s exactly how we approach every project.

From floor protection to cleanup and communication along the way, we take pride in making the experience just as good as the final result.
