How Installing Energy-Efficient Windows in Torrance Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could benefit you:
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Torrance, that’s about 117 pounds per year on average.
- Save money on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient windows can help lower that number, which helps you save $509 a year on your bills.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
Estimated Cost of Window Replacement in Torrance
Let’s take a look at the cost of replacing your windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Generally, Torrance homeowners can expect their window installations to range from $250 to $1,200. The average cost is at around $600. This is because the cost of window installations are based on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has significant deterioration. These installations are more involved and will increase the overall cost. A pocket installation involves replacing a window without removing the entire frame, which is usually less expensive than a full-frame installation.
If you’re not sure which type of window installation service you need, your installer can advise you. Typically, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Torrance
The EcoWatch Reviews team is different from other reviewers because we’re examining these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Torrance, we only included companies that cover the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Torrance.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company included in our guide to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of parts, cost, quality of installation, warranty, professionalism and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Torrance, CA Window Replacement FAQs
How much does window installation cost?

Which type of window should I get?
A window’s energy efficiency is affected by a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
