Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house’s efficiency can also have a big impact on home energy conservation. When it’s the middle of winter, your outdated and drafty windows could be making your home more difficult to heat and costing you more in power bills.
That’s also bad news for the environment because the extra energy required by old windows increases your carbon footprint.
Efficient windows are especially important in Hillside, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $290 each year.

How Installing Energy-Efficient Windows in Hillside Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 206 pounds.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date 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 damaging UV rays, reducing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Hillside
Windows come in various shapes, purposes and styles, so costs and services will differ considerably depending on your project. Below, we describe the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range from $200 to $1,200. 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 offer door installations, which will make your project cost more.
Whether or not you choose energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $290 a year on your energy bills in Hillside.
We recommend requesting free quotes from multiple window installers to find the one that works best for you.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
If you’re unsure which type of window installation service you should get, your installer can assist you. In general, the decision depends 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 Hillside
The EcoWatch Reviews team differs from most reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Hillside area so you can find a quality window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth 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 give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of parts, quality of installation, professionalism, cost, warranty and more.
Cost
This one is a give-and-take: as with other services, cheap window installers won’t always provide the highest quality service. Still, we want to make sure 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 be certain that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Hillside’s climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Hillside window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Hillside, NJ Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing one window is about $600 but can range between $200 and $1,200, depending on a few different factors. The price is generally dependent on the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which type of window is the best?
A window’s energy efficiency is influenced by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
What services do window replacement companies do?
Window installers will do the entire process — from replacing old windows with brand-new ones to cleaning up after the windows have been put in place. In addition, many companies offer window manufacturing, customization and repairs.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on energy costs, replacing all of the windows together is the only way to see a noticeable difference. However, if you have only a few windows that are damaged or leaky, you can replace just those.
