How Installing Energy-Efficient Windows in Palo Alto Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to make the switch:
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Palo Alto
When considering window installation, each company offers different services and costs. Let’s look at some typical costs and services.
How Much Do New Windows Cost?
On average, Palo Alto homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. These figures are based on specific characteristics of your installation, like material, size, the location of your home, number of windows, type and more.
It’s also worth noting that energy-efficient windows will usually cost more initially, but Energy Star predicts that switching out the windows on your Palo Alto home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first step when planning a replacement is to clarify whether you should get a full-frame or pocket installation.
A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you’re still trying to decide which type of installation you should get, you can talk to your installer and get their advice. The choice mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Palo Alto
In our hunt to make your home improvements easier and more eco-friendly in Palo Alto, EcoWatch landed on the above companies as the best window installation companies in the city. We have evaluated the top window installation companies in Palo Alto mostly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Palo Alto, we gave more points to companies that serve the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Palo Alto.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company on this list to make sure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don’t have positive feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers’ prices, 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 provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Palo Alto, CA Window Replacement FAQs
How much does window installation cost?
The typical cost to install a window ranges between $450 and $650. There are several factors that influence how much it costs, such as your property’s location, styles and sizes of windows, how energy-efficient the windows are, the materials used in designing the windows, the number of windows and local labor costs.
What kind of window is the most energy-efficient?
A window’s energy efficiency depends on several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
When should I use a window installation company?
You should use a window installation company whenever you need to upgrade your windows. Installing windows is a involved process that can take a lot of time, so it’s best left to the professionals.
What time of year is a good time to replace my windows?
Even though you can install windows any time of year, warmer weather is usually better for replacing windows. Additionally, it shouldn’t be raining, as rain can make the installation harder.
