Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although green energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house’s efficiency can also have a large impact on home energy conservation. Traditional, outdated windows could lead to spending more on electricity bills during the winter or summer months.

That’s also bad for the environment because the additional energy required by leaky windows increases your carbon footprint.

Unlike other sites, EcoWatch ranks window installation companies based on energy efficiency while also factoring in cost, customer satisfaction and service area.

Union City Window Cost Calculator

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Union City Saves You Money

By switching to energy-efficient windows, you can enjoy several benefits, including:

  • Save on power bills: After you install energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll require less energy to heat or cool your house.
  • Reduce 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  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Union City

Windows come in varying shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you can find from window installers.

How Much Do New Windows Cost?

Generally, Union City homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at approximately $600. But prices 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 installers also provide door installations and replacements, which have a higher price tag.

It’s important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Union City homeowners $531+ a year when replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

Full-frame installations entail replacing the full window, including the trim, sill and frame. Full-frame installations are necessary when you want a new style or your window has noticeable damage or rot. These installations are more involved and will raise the total cost. A pocket installation entails installing a new window without replacing the frame. This means instead of removing the whole unit and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re still debating which kind of installation to get, you can consult with your provider and get their advice. The choice mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Union City

In our search to find the most reliable, eco-friendly window installers in Union City, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated several window installers in Union City and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When choosing 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 give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction. 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, cost, warranty, professionalism, quality of installation and more.

Cost

This one is a give-and-take: as with most 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. That’s why window installation companies that have 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 a while. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Union City, CA Window Replacement FAQs

How much does window installation cost?

The national average cost to replace a single window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is usually dependent on the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

Which kind of window should I get?

A window’s energy efficiency is affected by several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.

What do window installers do?

Window installation companies will do the entire process — from replacing old windows with brand-new ones to cleaning up afterward. In addition, many companies offer window manufacturing, customization and repairs.

What time of year is a good time to replace my windows?

Even though you can install windows any time of year, warmer weather is often better for installing replacement windows. Additionally, the weather should be dry, because rain can make the installation harder.

Should I replace all my windows at the same time?

If you want to get more efficient windows and save money on your energy bills, replacing all your windows at the same time is the only way to gain that benefit. On the other hand, if you have only a few windows that are damaged or leaky, you can replace just those.
