How Installing Energy-Efficient Windows in Union City Saves You Money
There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Reduce your carbon footprint: In Union City, you can reduce your indirect greenhouse gas emissions by about 117 pounds per year once you install energy-efficient windows.
- Save money on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Union City
Let's go over the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Though the typical of installing a single window is around $600, it can range from $200 to $1,200. Costs will vary significantly based on the quality of your products, the current condition of your home, the number of windows you need and your location. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.
It's also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star predicts that upgrading the windows on your Union City home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We advise getting free quotes from several window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
The first step when planning a window replacement is to figure out whether you want a full-frame or pocket installation.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of damage. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are on the simpler end and won't carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Union City, the choice will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Union City
EcoWatch reviews are different from most reviews since we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings using the following methodology:
Service Area
Because this is a guide for Union City, we only included companies that serve the city. There are certainly reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Union City.
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 included on this list to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including professionalism, cost, quality of parts, warranty, quality of installation and more.
Cost
This one is a give-and-take: as with other services, cheap window companies won't always provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) 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 experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Union City, CA Window Replacement FAQs
What is the typical cost to install new windows in a home?
The average cost to install a window can range from $450 to $650. There are a variety of factors that affect the cost, including the number of windows, how energy-efficient the windows are, your property's location, local labor costs, the materials used in designing the windows and styles and sizes of windows.
What type of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
When do I need to use a window installation company?
You should hire a window installation professional whenever you need to upgrade your windows. Installing windows is a complicated process that can take a lot of time, so it's best left to the professionals.
How long does window installation usually take?
Because the average installation time is 30 minutes per window, about 16 windows can be installed during a typical 8-hour work day.
When is the best time of year to replace windows?
Though you can install windows any time of year, warmer weather is typically better for replacing windows. In addition, the weather should be dry, as rain can make the installation more difficult.
