How Installing Energy-Efficient Windows in Union Saves You Money
Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to take the plunge and make the switch:
- Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 206 pounds per year on average.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
- Save on energy bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your house.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Union
Windows come in varying shapes and sizes, so costs and services will vary remarkably. Here are the average costs and services that you'll find from window installers.
How Much Do New Windows Cost?
Even though the national average of replacing one window is about $600, it can range anywhere from $200 to $1,200. How much it will cost varies based on several factors, such as number of windows, material, the location of your home, size, type and more.
It's important to bear 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 $277+ a year when replacing single-pane windows.
Something else that affects the overall cost is the material you choose for your frame. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first question to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?
Full-frame installations are necessary when you want a new style or your window has a lot of rot. With this service, your installers will replace the complete window, including the frame, trim and sill. A pocket installation entails replacing a window without removing the complete frame, which tends to be cheaper than a full-frame installation.
Your window installation company will be able to advise you on the best type for your project. In Union, the decision will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Union
In our hunt to make your home improvements easier and more eco-friendly in Union, the EcoWatch team landed on the above companies as the top window installation companies in the city. We've assessed the best window replacement companies in Union primarily based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Union, we gave more points to companies that serve the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Union.
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 installer on this list to make sure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive feedback about their experience with a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most 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 offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Union's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Union window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Union, NJ Window Replacement FAQs
What is the average cost to install windows?
The national average cost of installing a window is around $600 but can range between $200 and $1,200, depending on several factors. The price is typically influenced by the type and material of the window, the location of your property and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the most energy-efficient?
A window's energy efficiency is affected by a variety of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
Can you install your own windows?
Although you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window replacement company can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
Should I replace all my windows at once?
If you're upgrading your windows to save on your energy bills, replacing all your windows together is the only way to gain that benefit. However, if you have only one or two windows that are broken or drafty, you can replace just those.
