Showroom Outside

Since our founding in Chatsworth in 1978, Progressive Insulation & Windows has grown into one of Southern California’s leading replacement window and insulation companies. We stand out above many of our competitors because of our commitment to provide excellence in the installation of our products. Though we now have more than 50 trained installers and sales reps, we still do business in the same customer-centered tradition that propelled us to success in our early days. We are still a family-owned and family-operated business that truly cares about the customer experience before, during, and after installation of any of our products.

A Licensed Specialty Contractor

Progressive Insulation & Windows is a fully licensed and insured contractor. In addition to a general B Class contractor’s license, we also hold specialty licenses in window glazing (C-17 license) and insulation (C-2 license). Feel free to check us out on the California Contractors State License Board website. We’re license #418046.
