• The Advanced Windows Advantage

    It all starts with a local, family-owned company—Advanced Window Systems has been successfully serving northern Illinois and southern Wisconsin since 1975. We are proud to be locally owned, to provide quality products and workmanship, and to be a part of our hometown Rockford area. 

    Advanced Window Systems possesses the highest quality and service standards, based on our decades of
    knowledge and experience in the window business. We feel our products speak for themselves and like to use
    the direct no non-sense approach: we’ll measure your windows, show you the different colors and styles,
    answer all your questions, and leave you with a quote that is easy to understand.
    We treat our customers—and their homes—with great respect and care.

    Meet the Family

    Matthew and Karla Schindler are proud to own Advanced Window Systems. What makes them proud? Matt started at the bottom, learning the estimation, installation, and service sides of the company. Today and every day, he continues to make sure that each job lives up to the Advanced Window Systems standards. Karla takes pride in running the day-to-day operation. When you call or stop in, she’ll be there to greet you, demo the windows, and handle any customer service needs—along with many other aspects of the business. Matthew and Karla’s son Matthew enjoys connecting with our customers and giving estimates, but is also no stranger to installation or service.

    Our Promise of Quality

    We guarantee the quality of our work because, unlike many window replacement companies, we use our own installation crew. By employing our own installers instead of using subcontractors, we have the ability to fulfill our promise of consistent, quality service. We control all facets of the operation to best serve our customers with the highest quality product, installation and service.

    Service & Installation

    Our professional team of installers will treat you and your home with great care and respect. We use the highest quality products and install with skill and precision. And, since we treat your home like our own,
    you can be assured that we will it clean and neat. For added peace of mind, our employee installers are
    fully insured with both liability and workers’ compensation insurance for complete protection.
