How Installing Energy-Efficient Windows in Morristown Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, including:
- Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Switching to energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
- Reduce your carbon footprint: In Morristown, you can reduce your indirect greenhouse gas emissions by about 206 pounds per year once you switch to energy-efficient windows.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Morristown
When looking into window installation, each company provides different services and prices. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. But prices vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which carry a higher price tag.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
We recommend getting free quotes from several window companies to find the one that works best for your budget.
What Services do Window Installers Offer?
Generally, there are two types of window installation services you can get: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which increase the overall 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 tearing out the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you’re hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Morristown, the choice will mostly be influenced by how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Morristown
In our search to find the most reliable, eco-friendly window installers in Morristown, EcoWatch landed on the above companies as the top window installation companies in the city. We’ve reviewed the top window installers in Morristown mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Morristown, we only included companies that cover the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Morristown.
Work Quality
When choosing new windows, the quality and range 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 consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have good feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to 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 provide a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that provide 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 installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Morristown, NJ Window Replacement FAQs
What is the average cost to install new windows in a home?
The typical cost of installing a single window can range from $450 to $650. There are several factors that affect the cost, including how energy-efficient the windows are, local labor costs, the number of windows, the materials used in designing the windows, your property’s location and styles and sizes of windows.
What type of window is the best for energy efficiency?
A window’s energy efficiency depends on a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
What services do window replacement companies offer?
Window installation professionals will do the entire process — from replacing old windows with new ones to cleaning up afterward. Additionally, many companies offer window manufacturing, customization and repairs.
Should I replace all my windows at the same time?
If you’re upgrading your windows because of energy-efficiency, replacing all of your windows at the same time is the only way to gain that benefit. However, if you have just one or two windows that are damaged or drafty, you can replace just those.
