How Installing Energy-Efficient Windows in Lewisboro Saves You Money
There are quite a few benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch are the following:
- Reduce your carbon footprint: In Lewisboro, you can cut your indirect greenhouse gas emissions by about 65 pounds per year once you upgrade to energy-efficient windows.
- More efficient energy usage in your household: Because the winters can get very cold in Lewisboro, homeowners usually rely on their heater a lot. Energy-efficient windows reduce the amount of heat that is lost through your windows, making it easier to keep your home warm.
- Better temperature control in your home: Living in a hot place like Lewisboro can often mean depending on your air conditioner to keep your house cool. Energy-efficient windows can reduce how hard your AC needs to work to cool your home.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
Estimated Cost of Window Replacement in Lewisboro
Let's go over the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
According to our research, the national average cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. This is because of the fact that the cost of window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.
Bear in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
When it comes to window replacements, there are typically two kinds that your provider will have: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, like insulation and drip edges, which increase the overall 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 entails replacing a window without removing the entire frame, which is usually cheaper than a full-frame installation.
Your window replacement company should be able to help you choose what's best for your needs. In Lewisboro, the decision will mostly depend on how old your home is and if there's any moisture damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Lewisboro
EcoWatch reviews are different from most reviews since we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them based on the following methodology:
Service Area
This one is 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 right window installation company near you.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer included on this list to make sure its contractors are well-qualified and that the company has received a lot 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 nice things to say about their experience with a certain window installation company, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, 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.
Lewisboro, NY Window Replacement FAQs
What is the typical cost to install new windows?
The national average cost to install one window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is often influenced by the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which kind of window should I get?
A window's energy efficiency is affected 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.
When do I need to use a window installation company?
You should hire a window installation company whenever you want to replace your windows. Installing windows is a complex process that can be difficult to do on your own, so it's best left to the professionals.
How long does window installation typically take?
Because the average installation time is 30 minutes per window, around 16 windows can be installed during an 8-hour work day.
