How Installing Energy-Efficient Windows in Greenwich Saves You Money
There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 206 pounds per year on average.
- Save money on electricity bills: Once you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating 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 Greenwich
Each window replacement company provides varying services and has different price points based on a few factors.
How Much Do New Windows Cost?
Although the typical of installing a single window is about $600, it can range anywhere from $200 to $1,200. These amounts are based on specific characteristics of your installation, including type, material, number of windows, size, the location of your home and more.
It's important to bear in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Greenwich homeowners $284+ a year when replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but offer 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 offer decent insulation for your home.
What Services do Window Installers Offer?
The first step when planning an installation is to decide whether you want a full-frame or pocket installation.
Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your professionals will replace the total window, including the frame, trim and sill. A pocket installation means replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.
If you're still debating which type of installation you need, you can consult with your provider and get their advice. The choice mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Greenwich
EcoWatch reviews differ from most reviews since we examine these companies through a sustainability lens. We've reviewed the top window installation companies in Greenwich primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut 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 Greenwich, we only included companies that provide services to the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Greenwich.
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 give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including cost, warranty, professionalism, quality of parts, quality of installation and more.
Cost
This one is a give-and-take: similar to most services, cheap window companies won't always provide the highest quality service. Still, we want to ensure 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. That's why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Greenwich's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Greenwich window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Greenwich, NJ Window Replacement FAQs
How much does window installation cost?
The national average cost of replacing one window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is typically dependent on the location of your property, the type and material of the window and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What type of window is the most energy-efficient?
A window's energy efficiency is affected by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
When do I need to use a window installation company?
You should use a window installation professional whenever you want new windows. Installing windows is a complex process that can be difficult to do on your own, so it's best handled by the professionals.
What time of year is a good time to replace my windows?
While you can install windows any time of year, warmer weather is typically better for installing replacement windows. Additionally, it shouldn't be raining, as rain can make the installation more difficult.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
