How Installing Energy-Efficient Windows in Greentree Saves You Money
There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Installing energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Greentree, that’s about 206 pounds per year on average.
Estimated Cost of Window Replacement in Greentree
Let’s take a look at the cost of replacing your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Although the typical cost of replacing a single window is about $600, it can range anywhere from $200 to $1,200. This is because the cost of window installations are based on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.
Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Another factor that affects the total cost is the material you select for your frame. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In general, there are two kinds of window replacement services you can get: full-frame and pocket installations.
Full-frame installations entail replacing the full window, including the trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has significant damage. Because these installations are more involved, they will increase the total cost. 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 carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
If you’re still trying to decide which type of installation you should get, you can ask your provider and get their advice. The decision mostly is influenced by the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Greentree
EcoWatch is different from most reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Greentree and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Greentree so you can find the best window installation company near you.
Work Quality
When selecting new windows, the quality and variety of services often plays 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 factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including professionalism, warranty, quality of parts, quality of installation, cost and more.
Cost
This one is a give-and-take: as with most services, cheap window installers may not 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 considerable investment, so you’ll want to make sure that investment is protected. Window installation companies that give you 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 proven track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Greentree, NJ Window Replacement FAQs
How much does window installation cost?
The average cost of replacing one window ranges from $450 to $650. There are a variety of factors that affect how much it costs, which include your property’s location, the number of windows, how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows and local labor costs.
What are the most common kinds of replacement windows?
The most common kinds of windows for homes include: transom windows, slider windows, bay windows, double-hung and single-hung windows, awning windows, casement windows and picture windows.
Can you replace your own windows?
Although it is possible to install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help ensure that the installation is done properly and that you won’t have to spend the time and effort to do it yourself.
When is it time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it’s probably time to replace all of them. By that point, they are typically less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
