How Installing Energy-Efficient Windows in Fremont Saves You Money
By switching to energy-efficient windows, you can enjoy several benefits, such as:
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 117 pounds per year on average.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Fremont
Let's take a look at the cost of window installation and the kinds of services offered by installers.
How Much Do New Windows Cost?
According to our research, the average cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. This is because the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.
Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $665 a year on your energy bills in Fremont.
Getting free quotes from several providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
There are generally two kinds of window replacement services: full-frame and pocket installations.
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 installing a new window without replacing the frame. This means instead of taking out the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Fremont
EcoWatch reviews are different from other reviews since we examine these companies through a sustainability lens. We've assessed the top window installers in Fremont primarily 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 lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Fremont, 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 Fremont.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each company in our guide to make sure its contractors are well-qualified and that the company has gotten tons 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 good things to say about their service from a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers are not going to provide the most 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
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Fremont's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Fremont window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Fremont, CA Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is usually influenced by the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the best for energy efficiency?
A window's energy efficiency depends on a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
Can I install my own windows?
If you're handy and know how to replace a window, it's possible to install your own windows. However, if you don't have the time or experience, we recommend getting a professional to do it for you.
When is it time to replace your windows?
Windows usually have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them looked at by an expert to determine if they need any repairs or replacements.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's most likely time to replace all of them. By that point, they are typically less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
