How Installing Energy-Efficient Windows in Union Saves You Money

There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

• Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
• Save on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
• Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 206 pounds per year on average.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Union

Let’s go over the cost of updating your windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

On average, homeowners in Union can anticipate that most window installations will range from $250 to $1,200, with the average cost at around $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 provide door installations and replacements, which carry a higher price tag.

It’s important to keep in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Union homeowners $290+ a year when replacing single-pane windows.

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 on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

When considering window installations, in general there are two kinds that your installer will have: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. As this type of installation requires more time and labor, it will cost more than a pocket installation. A pocket installation involves installing a new window within the old frame. So, instead of taking out the whole unit and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re not sure which type of window installation service you need, your installer can help you out. In general, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Union

In our search to find the most reliable, eco-friendly window installers in Union, the EcoWatch Reviews team examined many companies before settling on these. We have reviewed the top window replacement companies in Union mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Because this is a guide for Union, we only included companies that provide services to the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Union.

Work Quality

When picking new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have nice feedback about their experience with a certain window installation company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
