Certified windows backed by the Good Housekeeping Seal, with their quality and energy efficiency, to our neighbors throughout the area. Every day, our goal is to go above and beyond, ensuring customers have a positive experience and are elated with their final product.

Giving back

Along with high quality and exceptional service, corporate responsibility is integral to Window World of Rockford’s operations. As a locally owned business, we recognize our success is truly dependent on the community, and we’re committed to demonstrating our appreciation by giving back through acts of service.

Among recent philanthropic undertakings are a generous contribution to the All Veterans’ Memorial Park, allowing it to erect a Gulf War Memorial

In addition, the team helped create a special room for a young local girl through the Make-A-Wish Foundation and participated in “A Night In a Box,” which required sleeping outside to raise money to combat homelessness. With dedication to giving back exemplified by our leadership, company-wide belief in philanthropy has become our norm.
