How Installing Energy-Efficient Windows in Santa Clara Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways switching out your windows could help you:
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- Decrease your carbon footprint: By using less energy after you switch to Energy Star certified windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Santa Clara
Windows come in various shapes, styles and purposes, so costs and services will vary remarkably depending on your project. Below, we detail the average cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
Though the national average cost to install a single window is around $600, it can range anywhere from $200 to $1,200. But costs vary 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 and replacements, which carry a higher price tag.
Whether or not you pick energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $562 a year on your energy bills in Santa Clara.
Something else that affects the overall cost is the material of the frame you select. Aluminum frames are usually the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step of a replacement is to figure out whether you should get a full-frame or pocket installation.
Full-frame installations entail replacing the total window, including the frame, trim and sill. Full-frame installations are necessary when you want a new style or your window has noticeable damage. Because these installations are more involved, they will raise the total cost. Pocket installations are on the simpler end and won’t cost as much, as they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you’re unsure which type of window installation service you need, your installer should be able to help you out. Generally, the choice is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Santa Clara
In our hunt to make your home improvements easier and more eco-friendly in Santa Clara, the EcoWatch team chose the above companies as the top window installation companies in the city. We have reviewed the top window installers in Santa Clara primarily based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Santa Clara, we gave more points to companies that cover the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Santa Clara.
Work Quality
When selecting new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you choose. 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 patterns in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of parts, warranty, quality of installation, professionalism, cost and more.
Cost
This one is a give-and-take: as with other services, cheap window installers won’t always provide the most quality service. Still, we want to ensure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you’ll want to make sure that investment is well protected. Window installation companies that have 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 experience earn higher rankings by our standards. We like to see at least ten years of experience.
Santa Clara, CA Window Replacement FAQs
What is the average cost to replace windows?
The national average cost to replace one window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is usually influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What type of window is the best for energy efficiency?
A window’s energy efficiency is affected by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
What do window installation companies do?
Window installation professionals go to your property to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.
When is it 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 should probably 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.
