How Installing Energy-Efficient Windows in Westchester Saves You Money
There are several perks of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- Save on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Westchester, that’s about 449 pounds per year on average.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Westchester
Each window installer provides varying services and has different price points based on several factors.
How Much Do New Windows Cost?
The typical cost to replace a single window is about $600 but can range from $200 to $1,200. How much it will cost is based on several factors, such as type, number of windows, size, the location of your home, material and more.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Westchester homeowners $295+ each year after replacing single-pane windows.
Another factor that affects the total cost is the material of the frame you select. 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 are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
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 installers will replace the whole window, including the sill, trim and frame. Pocket installations are on the simpler end and won’t cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.
Your window installation company should be able to help you choose what’s best for your needs. In Westchester, the decision will mostly depend on how old your home is and if there’s any moisture damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Westchester
EcoWatch reviews differ from most reviews since we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Westchester and assigned rankings based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
When picking new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the highest rates of 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 cost, professionalism, quality of parts, warranty, quality of installation and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a serious investment, so you’ll want to be certain that investment is well protected. 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 a good track record in the industry. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Westchester, IL Window Replacement FAQs
What is the typical cost to install new windows in a home?
The typical cost to install a window ranges between $450 and $650. There are a variety of factors that affect the cost, including your property’s location, the number of windows, local labor costs, styles and sizes of windows, how energy-efficient the windows are and the materials used in designing the windows.
What type of window is the most energy-efficient?
A window’s energy efficiency is influenced by several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
Can you replace your own windows?
If you’re handy and have the time and patience to do the job right, it’s possible to install your own windows. However, if you don’t have the time or know-how, we don’t recommend doing it on your own.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is often better for replacing windows. Additionally, the weather should be dry, as rain can make the installation more difficult.
