How Installing Energy-Efficient Windows in East Palo Alto Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to consider making the switch:
- Save on power bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that amount, which helps you save more on your bills.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 117 pounds per year on average.
- Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- 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 damaging UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in East Palo Alto
Let's take a look at the cost of replacing your windows and the types of services offered by installers.
How Much Do New Windows Cost?
According to our market research, the average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost depends on several factors, such as type, the location of your home, material, size, number of windows and more.
It's also worth bearing in mind that energy-efficient windows will cost more initially, but Energy Star estimates that upgrading the windows on your East Palo Alto home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Something else that affects the total cost is the material you pick for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step when considering a window installation is to clarify whether you want a full-frame or pocket installation.
A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which increase the overall cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're not sure which kind of window installation service you should get, your installer can assist you. Generally, the decision is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in East Palo Alto
EcoWatch reviews are different from most reviews because we're examining these companies through a sustainability lens. We've reviewed the top window installation companies in East Palo Alto mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve East Palo Alto so you can find a quality window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, quality of parts, cost, warranty, quality of installation and more.
Cost
This one is a give-and-take: as with other services, cheap window installers may not provide the highest quality service. Still, we want to ensure we're highlighting companies that provide a variety 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 with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
East Palo Alto, CA Window Replacement FAQs
What is the typical cost to install new windows?
The typical cost to replace a window ranges between $450 and $650. There are a variety of factors that influence the price, such as how energy-efficient the windows are, your property's location, styles and sizes of windows, the materials used in designing the windows, the number of windows and local labor costs.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
What do window installation companies do?
Window installers travel to your house to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.
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, they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.
