How Installing Energy-Efficient Windows in Wantage Saves You Money
By upgrading to energy-efficient windows, you and your family can benefit in several ways, including:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of residential energy use. Installing energy-efficient windows can help lower that amount, which helps you save more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Better temperature control in your home: Living in a very cold place like Wantage often means depending on your heater to keep your house cool. Energy-efficient windows can reduce how hard your heating system needs to work to heat your home.
Estimated Cost of Window Replacement in Wantage
Windows come in different purposes, shapes and styles, so costs and services will vary remarkably depending on your project. Below, we detail the typical cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
According to our market research, the national average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. But costs will vary significantly depending on the number of windows you need, the quality of your products, the current condition of your home and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Wantage homeowners $289+ each year after replacing single-pane windows.
Asking for free quotes from multiple providers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
When considering window replacements, in general there are two types that your installer will offer: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, including insulation and drip edges, which raise the overall cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations are on the simpler end and won't carry as large a bill, as they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.
If you're unsure which window installation service you should get, your installer can help you out. Typically, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Wantage
In our search to find the most reliable, eco-friendly window installers in Wantage, EcoWatch chose the above companies as the top window installation companies in the city. We have decided to review the best window installers in Wantage mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Wantage, we paid more attention to companies that cover the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Wantage.
Work Quality
When choosing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you choose. We do give window installers higher marks 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 the majority of customers don't have nice things to say 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 installation companies are not going to provide the most quality service. Still, we want to make sure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a sizable investment, so you'll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Wantage's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Wantage window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Wantage, NJ Window Replacement FAQs
How much does window installation cost?
The national average cost to replace one window is around $600 but can range between $200 and $1,200, depending on several factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
The most common kinds of windows for homes are transom windows, awning windows, slider windows, bay windows, double-hung and single-hung windows, picture windows and casement windows.
Can you install your own windows?
Although it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, 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 need to be replaced.
