How Installing Energy-Efficient Windows in Newark Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more details about how switching out your windows could benefit you:
- Better temperature control in your home: Energy-efficient windows can cut back on the amount of heat lost through your windows when heating your home.
- Save on power bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save about $301 annually on your energy bills in Newark.
- 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 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- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty.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 value.
Estimated Cost of Window Replacement in Newark
When looking into window installation, each company provides different services and costs. Let's look at some average costs and services.
How Much Do New Windows Cost?
According to our market research, the average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. This is because of the fact that window installations are based on a variety of 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.
Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $301 a year on your energy bills in Newark.
We recommend getting free quotes from several window installation companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window without replacing the frame. This means instead of taking out the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Newark
EcoWatch reviews differ from most reviews, as we examine these companies through a sustainability lens. We've decided to review the top window installation companies in Newark mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you opt for. 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 patterns in recent online reviews 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 nearly every category, including professionalism, warranty, cost, quality of installation, quality of parts 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 ensure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Newark, DE Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost of installing one window is around $600 but can range between $200 and $1,200, based on several factors. The price is usually influenced by the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which kind of window should I get?
A window's energy efficiency is influenced by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
Can you install your own windows?
If you're handy and have the time and patience to do the job right, you may be able to install your own windows. But if you don't have the time or experience, we don't recommend it.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
