How Installing Energy-Efficient Windows in West Windsor Saves You Money
There are quite a few perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 206 pounds per year on average.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in West Windsor
Each window installation company offers varying services and has varying costs based on a few factors.
How Much Do New Windows Cost?
Generally, West Windsor homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost is at around $600. This is because of the fact that the cost of 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.
It’s important to note that windows with the best 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 West Windsor homeowners $319+ a year when replacing single-pane windows.
Costs will also vary depending on the material you pick for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using 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 provide decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services you can get: full-frame and pocket installations.
A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will be more expensive than a pocket installation. Pocket installations are simpler and won’t cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
Your window installation company can advise you on the best type for your project. In West Windsor, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in West Windsor
In our search to make your home improvements easier and more eco-friendly in West Windsor, the EcoWatch team examined many companies before deciding on these. We have assessed the best window replacement companies in West Windsor 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 have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for West Windsor, we gave more points to companies that serve the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in West Windsor.
Work Quality
When picking 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 opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, cost, warranty, professionalism, quality of parts and more.
Cost
This one is a give-and-take: as with most services, cheap window installation companies may not provide the highest 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
Protecting your investment in new windows is important. For that reason, 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 installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
