How Installing Energy-Efficient Windows in Nassau Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:
- Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by about 65 pounds.
- Save money on energy bills: Because energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save around $386 annually on your energy bills in Nassau.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Nassau
Each window installer provides varying services and has varying prices depending on several factors.
How Much Do New Windows Cost?
Typically, Nassau homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. But prices vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which have a higher price tag.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — especially during the winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Nassau homeowners $386+ a year after replacing single-pane windows.
Asking for free quotes from multiple providers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
The first step of a window installation is to think about whether you want a full-frame or pocket installation.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Nassau
EcoWatch reviews are different from other reviews since we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and ranked them using the following methodology:
Service Area
This one is pretty 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
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good things to say about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies may not provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a range 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 that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Nassau's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Nassau window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Nassau, NY Window Replacement FAQs
What is the typical cost to install windows?
The national average cost of installing one window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is often dependent on the location of your property, the size of the window and the type and material of the window. Also, remember 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 is the best?
Generally, double-pane windows will be 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 — that means they're certified energy-efficient by the U.S. Department of Energy.
When do I have to use a window installation company?
You should hire a window installation professional whenever you need new windows. Installing windows is a involved process that can be difficult to do on your own, so it's best handled by the professionals.
When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is often better for installing replacement windows. In addition, it shouldn't be raining, because rain can make the installation more difficult.
