How Installing Energy-Efficient Windows in Palo Alto Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to think about making the switch:

• Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
• Save money on energy bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if you have an older home.

Estimated Cost of Window Replacement in Palo Alto

Windows come in various shapes and sizes, so costs and services will vary tremendously. Here are the average costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

Typically, Palo Alto homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. Costs will differ significantly depending on the current condition of your home, the number of windows you need, the quality of your products and your location. Many window companies also offer door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.

It’s also worth noting that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading 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 a year for double-pane windows. How much you’ll save by installing 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 based on the kind of window material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first step when considering a window installation is to clarify whether you should get a full-frame or pocket installation.

Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot. With this service, your installers will replace the complete window, including the trim, frame and sill. Pocket installations are simpler and won’t cost as much, as they involve merely replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.

If you’re still trying to decide which kind of installation to get, you can consult with your installer and get their advice. The choice mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Palo Alto

EcoWatch is different from other reviewers because we evaluate these companies through a sustainability lens. We’ve decided to review the top window installers in Palo Alto mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Palo Alto, we gave more points to companies that provide services to the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Palo Alto.

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included on this list to make sure its contractors 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 very important review factor. If the majority of customers don’t have nice things to say about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers may not provide the highest 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

As discussed, windows are a significant investment, so you’ll want to be certain that investment is protected. Window installation companies that offer 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.
