Progressive Insulation & Windows was founded in Chatsworth in 1978 and has grown into one of Southern California's leading replacement window and insulation companies. We stand above many of our competitors because of our commitment to provide excellence in the installation of our products. Though we now have more than 70 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 operated business that truly cares about the customer experience before, during, and after installation of any of our products.

"This review is almost 2 years past due but because of family illness and death I kept putting it off and I greatly apologize for that. In March, 2020, I contacted Progressive after finding out Exodus, a company I hired to install a sliding door in the early 2000s was no longer in business and that the owner now works for Progressive. On a Sunday evening I had a problem closing the door by about 12 inches and left a frantic message on their voicemail. It probably seems silly but it was winter and I had an elderly parent living with me so I was very concerned with the cold even though I did everything I could to cover it up. Before end of business on Monday Progressive came out and fixed the (thankfully) very simple problem and asked for nothing in return. What more can anyone ask for? I will be forever grateful for their assistance."

Energy Efficiency Auditing questions, answered by experts

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.
