How Installing Energy-Efficient Windows in Gardena Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could benefit you:
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its value.
- Save on power bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save about $509 annually on your energy bills in Gardena.
Estimated Cost of Window Replacement in Gardena
Windows come in different purposes, styles and shapes, so costs and services will differ tremendously based on your project. Below, we go over the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Typically, homeowners in Gardena can expect that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. These figures vary based on the specifics of your installation, such as material, the location of your home, size, type, number of windows and more.
Bear in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material you pick for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?
A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which raise the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window without removing the whole frame, which is usually cheaper than a full-frame installation.
If you’re still debating which kind of installation you should get, you can ask your installer and get their advice. The choice mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Gardena
EcoWatch reviews are different from other reviews, as we’re examining these companies through a sustainability lens. We’ve evaluated the top window installers in Gardena mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Gardena so you can find the best window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive feedback about their experience with a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window installation companies may not provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why 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 a good track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Gardena, CA Window Replacement FAQs
How much should window installation cost?
The typical cost of installing a window ranges from $450 to $650. There are a variety of factors that influence the price, which include your property’s location, local labor costs, the materials used in designing the windows, styles and sizes of windows, the number of windows and how energy-efficient the windows are.
Which type of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’re getting the most energy-efficient windows, look for models that have the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
If you’re handy and have experience with similar home improvement projects, it’s possible to install your own windows. However, if you don’t have the time or skills, we don’t recommend it.
When is it time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
How long does it take to install windows?
Because the average installation time is 30 minutes per window, about 16 windows can be installed during a typical 8-hour work day.
