Calculate how much you can expect to pay for window installation and replacement in Watchung, NJ using our customized window cost calculator.

How Installing Energy-Efficient Windows in Watchung Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more details about how switching out your windows could benefit you:
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Switching to energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- More efficient energy usage in your household: In Watchung where the winters can be very cold, energy-efficient windows lower how much heat is lost through your windows, which makes it easier to keep your home warm.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Watchung
Windows come in various shapes, purposes and styles, so costs and services will differ tremendously depending on several factors. Below, we go over the typical cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
On average, Watchung homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at approximately $600. But prices vary remarkably 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 provide door installations, which will add extra costs to your project.
It's also worth noting that energy-efficient windows will cost more upfront, but Energy Star estimates that switching out the windows on your Watchung home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, although it depends if 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 shown to be more efficient.
What Services do Window Installers Offer?
When it comes to window installations, in general there are two kinds that your installer will have: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window without taking out the complete frame, which is generally cheaper than a full-frame installation.
Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Watchung
EcoWatch is different from other reviewers, as we look at these companies through a sustainability lens. We've reviewed the best window replacement companies in Watchung mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Watchung so you can find a quality window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each company on this list to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have good things to say about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Watchung's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Watchung window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Watchung, NJ Window Replacement FAQs
How much does window installation cost?
The average cost to replace a window ranges between $450 and $650. There are many factors that affect how much it costs, such as the number of windows, the materials used in designing the windows, styles and sizes of windows, your property's location, how energy-efficient the windows are and local labor costs.
What are the different kinds of windows?
There are various kinds of windows you can get for your house, including awning windows, double-hung and single-hung windows, picture windows, slider windows, casement windows, transom windows and bay windows.
Can you install your own windows?
Although you can install your own windows, doing so requires a lot of time and handiness. Using a window replacement company can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
What time of year is a good time to replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
