How Installing Energy-Efficient Windows in Clarkstown Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways switching out your windows could help you:
- Better temperature control in your home: Living in a hot place like Clarkstown can often mean depending on your air conditioner to keep your home cool. Energy-efficient windows can lower how hard your AC needs to work to cool your home.
- More efficient energy usage in your household: Because the winters can get very cold in Clarkstown, homeowners usually rely on their heater during that time. Energy-efficient windows cut back on the amount of heat that is lost through your windows, making it easier to keep your home warm.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- Decrease your carbon footprint: By using less energy once switching to Energy Star certified windows, you'll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Clarkstown
Windows come in different purposes, styles and shapes, so costs and services will differ remarkably depending on several factors. Below, we go over the typical cost and services that you'll find from window installation companies.
How Much Do New Windows Cost?
On average, Clarkstown homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. These numbers are based on specific characteristics of your installation, such as the location of your home, size, material, type, number of windows and more.
With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more off the bat, 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 Clarkstown homeowners $333+ a year after replacing single-pane windows.
The cost of your window installation will also vary based on the type of window material you choose for the frames. Wood windows are generally the most expensive, though it depends if they are 100% 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?
The first step of a window installation is to decide whether you should get a full-frame or pocket installation.
A full-frame installation is a replacement of the full window. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won't cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.
Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Clarkstown
EcoWatch reviews are different from most reviews because we look at these companies through a sustainability lens. We've assessed the top window installers in Clarkstown primarily based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Clarkstown, we only included companies that cover the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Clarkstown.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company included on this list to ensure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including cost, warranty, professionalism, quality of installation, quality of parts and more.
Cost
This one is a give-and-take: similar to other services, cheap window installers won't always provide the most quality service. Still, we want to ensure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a sizable investment, so you'll want to make sure that investment is 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 good 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.
Clarkstown, NY Window Replacement FAQs
What is the average cost to replace windows in a home?
The typical cost to replace a single window can range from $450 to $650. There are a variety of factors that affect how much it costs, which include the number of windows, your property's location, how energy-efficient the windows are, local labor costs, styles and sizes of windows and the materials used in designing the windows.
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 are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
Even though you can install your own windows, doing so is time-consuming and requires a lot of handiness. Hiring a professional can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.
Should I replace all my windows at the same time?
If your windows are more than 20 years old, it's most likely time to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less time.
