How Installing Energy-Efficient Windows in Nanuet Saves You Money
When you upgrade to energy-efficient windows, you may see several benefits, such as:
- Reduce your carbon footprint: By using less energy after you upgrade to energy-efficient windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that number, which helps you save some money on your bills.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in Nanuet
Windows come in different styles, purposes and shapes, so costs and services will vary greatly depending on your project. Below, we detail the typical cost and services that you’ll find from window installation companies.
How Much Do New Windows Cost?
The national average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. But costs will differ considerably based on the current condition of your home, the number of windows you need, the quality of your products and your location. A lot of window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.
It’s important to bear in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Nanuet homeowners $333+ a year when replacing single-pane windows.
We advise requesting free quotes from several window companies to find the one that works best for your budget.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations are usually recommended when you want a new style or your window has significant rot. With this service, your installers will replace the whole window, including the sill, frame and trim. A pocket installation involves installing a new window within the existing frame. So, instead of tearing out the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window replacement company should be able to help you decide what’s best for your needs. In Nanuet, the decision will mostly be based on how old your home is 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 examine your frames and window sills.

How We Choose the Best Window Installers in Nanuet
In our hunt to make your home improvements easier and more eco-friendly in Nanuet, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Nanuet area so you can find the right window installation company near you.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have good feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you’ll want to be certain that investment is well protected. Window installation companies that give you 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.
Nanuet, NY Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is typically dependent on 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 a decent amount of money a year in energy bills.
Which type of window should I get?
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 typically the most energy-efficient since they are certified by the U.S. Department of Energy.
Can I install my own windows?
If you’re handy and have experience with installing a replacement window, it’s possible to install your own windows. However, if you don’t have the time or experience, we recommend hiring a professional.
What time of year is the best time to replace my windows?
Replacement windows can be installed at any time, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your house, so the temperature outside doesn’t necessarily matter that much. What’s most important is that the weather should be dry.
