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 Traditional, outdated windows could lead to spending more on electricity bills during the winter or summer months.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.

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

Energy-efficient windows can provide benefits in more than one way. Here are a few reasons you may want to make the switch:

  • Save on power bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, they can help you save around $531 annually on your energy bills in Union City.
  • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 117 pounds.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky.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 value.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.

Estimated Cost of Window Replacement in Union City

Each window replacement company offers varying services and has varying costs based on a few factors.

How Much Do New Windows Cost?

On average, Union City homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at about $600. But prices vary 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 add extra costs to your project.

It’s also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Union City home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

Generally, there are two types of window replacement services companies provide: full-frame and pocket installations.

A full-frame installation is a replacement of the total window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

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 be influenced by how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Union City

EcoWatch is different from most reviewers since we examine these companies through a sustainability lens. We have decided to assess the top window installation companies in Union City primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Union City so you can find a quality 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 overall efficiency and performance as the brand of window you get. 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 customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, warranty, professionalism, quality of installation, quality of parts and more.

Cost

This one is a give-and-take: as with other services, cheap window companies are not going to provide the most quality service. On the other hand, 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, windows are a hefty investment, so you’ll want to make sure that investment is well 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 years of 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

How much should a window install cost?

The typical cost of installing one window can range between $450 and $650. There are a variety of factors that influence how much it costs, which include styles and sizes of windows, local labor costs, how energy-efficient the windows are, the number of windows, your property’s location and the materials used in designing the windows.

Which type of window should I get?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not 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 — they’re certified energy-efficient by the U.S. Department of Energy.

What services do window replacement companies do?

Window installation professionals go to your house 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.

What time of year is the best time to replace my windows?

Replacement windows can be installed any time of the year, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.

Should I replace my windows all at the same time?

If your windows are greater than 20 years old, you most likely need to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
