How Installing Energy-Efficient Windows in Fremont Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:
- Better temperature control in your home: Energy-efficient windows can cut back on how much heat is lost through your windows when heating your home.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
- Save money on energy bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save about $531 annually on your energy bills in Fremont.
Estimated Cost of Window Replacement in Fremont
Let's go over the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Generally, Fremont homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at about $600. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which will make your project cost more.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
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 if they are solid 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 thing to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window replacement company will be able to help you understand what's best for your needs. In Fremont, the decision will mostly be based on the age of your home and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Fremont
In our hunt to find the most reliable, eco-friendly window installers in Fremont, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated several window installers in Fremont and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Fremont so you can find the best window installation company near you.
Work Quality
When choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have nice feedback about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installers won't always provide the most quality service. Still, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies that give you 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 installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Fremont, CA Window Replacement FAQs
What is the typical cost to install new windows in a home?
The typical cost to replace a window ranges from $450 to $650. There are a variety of factors that influence how much it costs, which include local labor costs, the number of windows, how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows and your property's location.
What are the kinds of windows?
The most common kinds of windows for homes are awning windows, slider windows, transom windows, picture windows, bay windows, casement windows and double-hung and single-hung windows.
Can I replace my own windows?
If you're handy and have the time and patience to do the job right, it's possible to install your own windows. However, if you don't have the time or experience, we recommend hiring a professional.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is often better for installing replacement windows. In addition, the weather should be dry, because rain can make the installation harder.
