How Installing Energy-Efficient Windows in Tenafly Saves You Money
When you upgrade to energy-efficient windows, you may see several benefits, such as:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- Save money on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Tenafly, that’s about 206 pounds per year on average.
- 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 Tenafly
Windows come in different purposes, styles and shapes, so costs and services will differ greatly depending on your project. Below, we describe the average cost and services that you’ll find from window installers.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range from $200 to $1,200. This is because of the fact that window installations are based on several factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.
It’s also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your Tenafly home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you’ll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are generally the most expensive, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
In general, there are two types of window replacement services you can get: full-frame and pocket installations.
Full-frame installations involve replacing the total window, including the sill, trim and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage or rot. These installations are more involved and will raise overall costs. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you’re still debating which type of installation to get, you can consult with your provider and get their advice. The choice mostly depends on the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Tenafly
The EcoWatch Reviews team differs from most reviewers because we look at these companies through a sustainability lens. We have decided to assess the best window installers in Tenafly mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Tenafly, we only included companies that cover the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Tenafly.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you opt for. 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
Customer feedback is another super important review factor. If most customers don’t have positive feedback about their experience with a certain installer, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installation companies won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer 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 with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Tenafly’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Tenafly window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Tenafly, NJ Window Replacement FAQs
What is the typical cost to replace windows?
The average cost of installing a window ranges from $450 to $650. There are a variety of factors that affect the price, including the materials used in designing the windows, your property’s location, how energy-efficient the windows are, styles and sizes of windows, local labor costs and the number of windows.
Which type of window is the best?
A window’s energy efficiency is affected by several 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.
Can you replace your own windows?
If you’re handy and know how to replace a window, you may be able to install your own windows. But if you don’t have the time or know-how, we don’t recommend it.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into the house, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on your energy bills, replacing all the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are broken or leaky, you can replace just those.
