Custom window installation for Wisconsin buildings

Add a unique focal point to your living space with a specialty shape window. Whether you want a trapezoid, hexagon, circle or other shapes of window— our licensed Wisconsin window contractors can build you a custom solution. Specialty windows are perfect for maximizing the view of your Wisconsin backyard or filling your interior with sunlight. Choosing a polygon window can be great for utilizing awkward empty spaces on your walls. The wow factor of a stylish specialty window can dramatically increase perceived property value, making the investment pay for itself.

How much do specialty windows cost?

The cost of specialty windows can vary widely depending on several factors, including the type of window, the materials used, the size of the window, the complexity of the design and the geographic location of the project.

For example, a custom-made stained glass window could cost several thousand dollars, while a small, standard-sized octagon window might only cost a few hundred dollars. For a more exact estimate, use our Wisconsin window replacement cost calculator. For more expensive projects, take advantage of our Wisconsin window financing to split up your lump sum into affordable monthly payments.

Working with Infinity Exteriors has been great so far. Our salesman Tom was very attentive and worked around our schedule without complaint. We felt we got honest answers and were never pushed. We are very much looking forward to having them do our windows and siding project.
