Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home's energy efficiency can also have a considerable impact on home energy conservation. According to the Department of Energy, heat gained or lost through outdated, drafty windows could represent 25-30% of heating and cooling usage.
Replacement windows improve your home's insulation, not only making you and your family more comfortable during the summer and winter, but also saving you money and helping the environment.
Efficient windows are particularly important in Flemington, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $259 each year.

How Installing Energy-Efficient Windows in Flemington Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to consider making the switch:
- 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.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Flemington, that's about 206 pounds per year on average.
- Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
- Save on electricity 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 decrease that amount, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Flemington
When researching window installation, each company offers varying services and prices. Let's look at some average costs and services.
How Much Do New Windows Cost?
Even though the national average of replacing one window is around $600, it can range anywhere from $200 to $1,200. How much it will cost varies depending on several factors, such as number of windows, type, size, material, the location of your home and more.
It's important to keep in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Flemington homeowners $259+ a year when replacing single-pane windows.
Getting free quotes from multiple installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first step of a window replacement is to decide whether you want a full-frame or pocket installation.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are on the simpler end and won't cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
Your window replacement company will be able to help you understand what's best for your needs. In Flemington, the decision will mostly be based on the age of your windows and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Flemington
In our hunt to find the most reliable, eco-friendly window installers in Flemington, EcoWatch evaluated many companies before deciding on these. We've decided to evaluate the top window installers in Flemington mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Because this is a guide for Flemington, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Flemington.
Work Quality
When it comes to new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including professionalism, cost, quality of installation, quality of parts, warranty and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Flemington's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Flemington window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Flemington, NJ Window Replacement FAQs
How much should a window install cost?
The national average cost of replacing a single window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is typically influenced by 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 upfront but can save you hundreds of dollars a year in energy bills.
What type of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies do?
Window installers travel to your house to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.
When is the best time of year to replace 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 house, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
How often do you need to replace windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
