Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's energy efficiency can also have a considerable impact on home energy conservation. Drafty windows can make your home uncomfortable in the summer or winter.
Replacement windows improve your home's insulation, not only making you and your family more comfortable during the summer and winter, but also saving you money and helping the environment.
Efficient windows are particularly important in Westchester, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $295 each year.

How Installing Energy-Efficient Windows in Westchester Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how switching out your windows could help you:
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Better temperature control in your home: When you reside in a place like Westchester where the winters can be very cold, you usually have to rely on your heater to keep your house warm. Energy-efficient windows can decrease how hard your heater needs to work to heat your home.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Upgrading to energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Westchester
Windows come in various styles, purposes and shapes, so costs and services will differ remarkably depending on your project. Below, we describe the typical cost and services that you'll find from window replacement companies.
How Much Do New Windows Cost?
Typically, Westchester homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at around $600. These numbers vary depending on the specifics of your installation, like size, the location of your home, material, number of windows, type and more.
It's important to remember that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Westchester homeowners $295+ a year when replacing single-pane windows.
The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services companies offer: full-frame and pocket installations.
A full-frame installation replaces the entire window, such as the sill, frame, trim and the window panes. Because this kind of installation is more involved, it will cost more than a pocket installation. Pocket installations are on the simpler end and won't carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.
If you're still debating which kind of installation to get, you can ask your installer and get their recommendation. The decision mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Westchester
EcoWatch reviews are different from most reviews, as we assess these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them using the following methodology:
Service Area
Since this is a guide for Westchester, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Westchester.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you opt for. 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
We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including quality of installation, cost, quality of parts, professionalism, warranty and more.
Cost
This one is a give-and-take: as with other services, cheap window installers won't always provide the most 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 to many homeowners. That's why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Westchester's climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Westchester window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Westchester, IL Window Replacement FAQs
How much does window installation cost?
The typical cost to replace a window ranges from $450 to $650. There are many factors that influence the cost, which include how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, the number of windows, local labor costs and your property's location.
What are the different kinds of windows?
The most common kinds of windows for homes include: awning windows, transom windows, casement windows, slider windows, bay windows, picture windows and double-hung and single-hung windows.
Can you replace your own windows?
If you're handy and have experience with similar home improvement projects, it's possible to install your own windows. However, if you don't have the time or know-how, we recommend hiring a professional.
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. Most importantly, the weather should be dry.
