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."

"Buyer Beware ? After the fires burned our gate we placed an order with Mulholland Brand under the assumption that they could deliver a specific product, as outlined in our original agreement. However, during a technician's visit to take measurements, we were informed that they would be unable to provide what was initially contracted & that it was backordered. Given the multiple red flags, vague and shifting details regarding design and timelines, and their ultimate inability to deliver the agreed-upon product, we chose to cancel the order. Importantly, this cancellation occurred before any fabrication or manufacturing began. Despite this, Mulholland Brand withheld $1,200 from our reimbursement without any prior notice or clear justification. Perhaps this practice of retaining fees was simply because a technician came to take measurements?ironically, the visit that confirmed they couldn't fulfill the original product in our agreement. Stay away Unethical business practices.. "

We believe the future is clean, renewable energy and with your help we are committed to creating it together. Customer satisfaction is a crucial aspect and the cornerstone of our business. As a result, we have earned the prestigious Diamond Certification 4 years in a row, along with the 2019 Angie’s List Super Service Award.

Check out our promos to take advantage of our best deals. And ask about our Referral Program that allows customers like you to earn cash bonuses for referring friends and family!

"No doubt they hire great installation people, but their communication and honoring their quotes has little to be desired. I will elaborate. I was given a quote, left on my voicemail. I responded the next day letting NRG know I accepted their quote. 1 week later I received a phone call telling me they wouldn't honor the quote give, and they cited the reasons as Tarif's. This was back in April 2025. I still went with NRG, albeit at a$1000.00 increase. The second reason I wouldn't recommend this company, and this for me is the final straw, after installing my solar NRG didn't let me know I needed to have an ESR release, in layman's terms this is necessary for your power company to accept your new solar system. I found out this information when they contacted me in August 2025. NEG blamed the company who upgraded my Electrical Panel. NRG INSTALLED MY SOLAR AFTER THE PANEL WAS UPGRADED. Since this company doesn't communicate with its clients I would say go with another company."

We test, diagnose, and cure energy efficiency, health, indoor air quality and comfort issues in your home. Our “Check Up” is a comprehensive home energy audit combining building science and modern detection devices to evaluate the energy efficiency level of your whole home. Our detailed report addresses your concerns and prioritizes the recommended upgrades. We are licensed and certified to do the work but don’t sub it out. We own our own air sealing, insulation removal and blowing equipment, and have a heating and air conditioning license and crew. After our upgrades our customers save 20% to 50% off their energy bills all while making their home energy efficient, healthier, and more comfortable. All of our employees have gone through a through background check. We take the utmost care when testing your home and even wear scrubs and booties and put down protective clothes to protect your home.

"I had my HVAC system replaced along with new insulation, new bathroom heaters, new ductwork and a new hydronic water heater. Needless to say this was a large job with a lot of moving parts. I can’t say enough good things about Building Doctors, they made my house state of the art in terms of comfort and energy efficiency. They always made my job a priority, none of that disappearing for days like I have experienced with other contractors. They were very professional, knew their stuff and made sure to leave my house as tidy as possible considering the magnitude of the work. They helped me complete the paperwork to qualify for rebates which was much appreciated. It has been 4 years since the job was completed and the system still works beautifully. I have continued with them for maintenance on the system and they have always been friendly, professional and prompt. Recently the Department of Water and Power in Pasadena came out to do an inspection of my system as part of a program they have to cut energy usage. When I told them I had used Building Doctors to install the system they commented that they have done “A lot of work with them and they are top of the line.” I couldn’t agree more."

Energy Efficiency Auditing questions, answered by experts

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.

An average, 400-square-foot electric heated driveways consume approximately $3 per hour in terms of electricity. The price may slightly fluctuate depending on your local energy cost. A simple formula to calculate your heated driveway’s total wattage consumption is by multiplying the square footage by 50 watts and then dividing it by 1,000 to get the kilowatt number. Multiply that with your local energy cost per hour and there you have the hourly operating cost.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

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. 

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.
