Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house's efficiency can also have a large impact on home energy conservation. If your house has traditional, outdated windows, your AC or heater could be working overtime to heat or cool your house. This means higher energy bills.
That's bad news for your bank account and the environment, but one of the best window installation companies can help with that.
Efficient windows are especially important in National City, where summers are long and hot. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $491 a year.

How Installing Energy-Efficient Windows in National City Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, such as:
- Better temperature control in your home: When you live in a place like National City where the winters can get chilly, you usually have to depend on your heater to keep your house warm. Energy-efficient windows can cut back on how hard your heater needs to work to heat your home.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In National City, that's about 117 pounds per year on average.
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in National City
Windows come in various shapes, purposes and styles, so costs and services will differ remarkably depending on several factors. Below, we detail the typical cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
According to our research, the average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. But prices differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which will add extra costs to your project.
Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Asking for free quotes from multiple companies is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
The first question to ask yourself when getting new windows is: Do you want a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want a new style or your window has a lot of rot or deterioration. With this service, your installers will replace the complete window, including the sill, frame and trim. A pocket installation involves replacing a window within the existing frame. So, instead of removing the whole unit and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're still debating which kind of installation to get, you can talk to 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 National City
In our hunt to find the most reliable, eco-friendly window installers in National City, the EcoWatch team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Since this is a guide for National City, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in National City.
Work Quality
When installing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have nice feedback about their service from a certain company, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a hefty investment, so you'll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
National City, CA Window Replacement FAQs
What is the average cost to install windows in a home?
The national average cost to install a single window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually influenced by the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
When do I need to use a window installation company?
Unless you're handy and have the time to replace your own windows, we recommend hiring the pros. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and safer alternative.
How do you know it's time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
