Why you can trust EcoWatch
A guide on the best window installation companies in Nassau may not seem like the most compelling article on the EcoWatch site, but trust us, windows have a more direct impact on your life than you might realize. The Department of Energy estimates that heat or cool air lost through old or damaged windows could make up close to 30% of residential energy climate costs. In Nassau, where the power bills are an average of $21 per month, that's almost $$73 per year wasted.
That's bad for both your bank account and the environment, but one of the best window installation companies can help with that.
So if you're constructing a new home, renovating or replacing your windows in Nassau, you've found the best place to get started.

How Installing Energy-Efficient Windows in Nassau Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to consider making the switch:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Decrease your carbon footprint: By using less energy after you switch to Energy Star certified windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Save on power bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save about $257 annually on your energy bills in Nassau.
Estimated Cost of Window Replacement in Nassau
Windows come in varying purposes, styles and shapes, so costs and services will vary tremendously based on several factors. Below, we detail the typical cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
On average, Nassau homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. But prices differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which will add extra costs to your project.
It's also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that upgrading the windows on your Nassau home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Another factor that affects the total cost is the material of the frame you choose. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
There are generally two types of window installation services: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which increase the total cost of the project. It's also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves installing a new window within the old frame. This means instead of removing the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company can recommend the best type for your project. In Nassau, the choice will mostly be influenced by the efficiency of your home and the age of your existing frames.

How We Choose the Best Window Installers in Nassau
In our hunt to make your home improvements easier and more eco-friendly in Nassau, the EcoWatch Reviews team 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 self-explanatory, but we've chosen to highlight window installers that serve Nassau so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you choose. 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 customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of installation, warranty, cost, professionalism, quality of parts and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, 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 to many homeowners. That's why window installation companies that offer 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 been in the industry for a while. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Nassau, NY Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is generally dependent on the type and material of the window, the location of your property and the size 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.
What kind of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be 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 — that means they're certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies offer?
Window installation professionals go to your property to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others install their own windows. The installer will also clean up after the installation.
What time of year is a good time to replace my windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
