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• Protect your investment: When you have an older home, your windows could also be outdated or leaky.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.
