Why you can trust EcoWatch
Although eco-friendly energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home's efficiency can also have a big impact on home energy conservation. The Department of Energy estimates that heat gained or lost through outdated or drafty windows could account for close to 30% of residential energy climate costs. In Jefferson, where the power bills are an average of $23 per month, that's almost $$83 per year wasted.
Fortunately, helping you save money with efficient windows also aligns with our goals of reducing energy usage for the environment.
Because windows are so important for your home, selecting the right company for you is a big decision to make. That's why the EcoWatch team has curated this list of the best window replacement companies, so you can more easily make an informed decision.

How Installing Energy-Efficient Windows in Jefferson Saves You Money
When you switch to energy-efficient windows, you may see a few perks, such as:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of household energy use. Upgrading to energy-efficient windows can help reduce that amount, which helps you save $287 a year on your bills.
- More efficient energy use in your home: In Jefferson where the winters can be very cold, energy-efficient windows cut back on the amount of heat that is lost through your windows, which makes it easier to keep your home warm.
Estimated Cost of Window Replacement in Jefferson
Let's go over the cost of replacing your windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range anywhere from $200 to $1,200. These figures vary based on specific characteristics of your installation, like type, material, the location of your home, number of windows, size and more.
Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material you choose for your window frames. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first step when considering an installation is to think about whether you need a full-frame or pocket installation.
Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the entire window, including the frame, sill and trim. A pocket installation entails installing a new window within the old frame. This means instead of removing the whole window and reinstalling it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're still debating which type of installation to get, you can consult with your provider and get their recommendation. 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 Jefferson
In our hunt to find the most reliable, eco-friendly window installers in Jefferson, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We have decided to review the top window replacement companies in Jefferson primarily 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 can lower energy 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 the Jefferson area so you can find the right window installation company near you.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
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 most other categories, including cost, quality of parts, warranty, quality of installation, professionalism and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers may not provide the most quality service. On the other hand, we want to make sure we're highlighting companies that offer a range 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 that provide lengthy warranties for products, parts and installation (aka workmanship) 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.
Jefferson, NJ Window Replacement FAQs
How much does a window install cost?
The average cost of installing a single window ranges from $450 to $650. There are a variety of factors that affect how much it costs, including how energy-efficient the windows are, the number of windows, the materials used in designing the windows, styles and sizes of windows, your property's location and local labor costs.
What are the different types of windows?
There are various kinds of windows you can get for your home, including slider windows, bay windows, picture windows, transom windows, double-hung and single-hung windows, casement windows and awning windows.
Do I really have to use a window installation company?
You should hire a window installation company whenever you need to upgrade your windows. Installing windows is a involved process that can be difficult to do on your own, so it's best left to the professionals.
What time of year is the best time to replace my windows?
Replacement windows can be installed any time of the year, 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 your home, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
