​​​​Janesville Replacement Window Company

Did you know that up to one-third of your home’s total energy loss could be due to outdated windows and doors? Upgrading the windows of your Janesville home is one of the best ways to enhance energy efficiency, save money, and increase your overall property value. 

At Mad City Windows, we offer only the highest-quality replacement windows that have been proven to withstand the Wisconsin climate while adding a touch of sophistication and style.

No matter the size or design of your preferred replacement windows in Janesville, we’re Wisconsin’s #1 ranked remodeler, and we’re certain to have a product to suit you! Just a few of our most popular choices include:

  • Bay and Bow Windows
  • Double Hung Windows
  • Garden Windows

Make a Stately Impression with Bay or Bow Windows

Not all Janesville replacement windows are made to blend in—and Mad City’s bay and bow windows are proof of that! These uniquely three-dimensional windows create an immediate focal point for any home, inviting tons of natural light through as many as five large glass panes. Work with our window designers to choose your preferred frame color, window units, and other styling details, and then relax while our factory-certified crews complete the installation!

Double the Airflow of Your Janesville Replacement Windows

If your primary concern for your next window installation revolves around ventilation, consider Mad City’s easy-to-use double-hung windows. Whereas conventional windows have just one sash, double-hung windows have two! That gives you twice the space for airflow in the same-sized window opening. These Janesville replacement windows are also:

  • Built with energy-saving glass and frame features
  • Customized to your home’s interior and exterior style
  • Easy to tilt in for hazard-free cleaning
  • Backed by comprehensive warranties

Add Practical Space in a Charming Garden Window

Compared to standard flat windows, garden windows are another eye-catching design. Similar in concept to bay or bow windows, these windows jut out from your home’s outer wall with clear glass on all sides. As a result, you’ll have a convenient and sun-filled alcove that’s perfectly sized for plants, herbs, or household décor. Best of all, our Janesville replacement windows are made with insulating glass that never compromises on energy efficiency!
