How Installing Energy-Efficient Windows in Elwood Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change are the following:
- Reduce your carbon footprint: In Elwood, you can reduce your indirect greenhouse gas emissions by about 307 pounds per year when you upgrade to energy-efficient windows.
- Better temperature control in your home: When you reside in a city like Elwood where the summers can be quite hot, you often need to depend on your air conditioner to keep your home cool. Energy-efficient windows can lower how much cool air is lost through your windows when cooling your home.
- Better temperature control in your home: When you live in a city like Elwood where the winters can be very cold, you usually need to rely on your heater to keep your house warm. Energy-efficient windows can reduce how hard your heater needs to work to heat your home.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
Estimated Cost of Window Replacement in Elwood
When considering window installation, each company provides varying services and costs. Let's take a look at some typical costs and services.
How Much Do New Windows Cost?
Even though the national average of replacing a single window is about $600, it can range anywhere from $200 to $1,200. But prices vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which have a higher price tag.
With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Elwood homeowners $215+ each year after replacing single-pane windows.
Requesting free quotes from several installers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
There are typically two types of window replacement services: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of deterioration. With this service, your professionals will replace the complete window, including the frame, trim and sill. A pocket installation entails replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
Your window installation company will be able to recommend the best type for your project. In Elwood, the decision will mostly be influenced by the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Elwood
In our search to find the most reliable, eco-friendly window installers in Elwood, EcoWatch examined many companies before settling on these. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings using the following methodology:
Service Area
Since this is a guide for Elwood, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Elwood.
Work Quality
We're certain that you're looking for professionals who do a great 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 a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have nice feedback about their experience with a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installation companies may not provide the most quality service. On the other hand, we want to make sure 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 give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. 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.
Elwood, NY Window Replacement FAQs
How much does a window install cost?
The national average cost of installing a window is about $600 but can range between $200 and $1,200, based on several factors. The price is generally influenced by the location of your property, the type and material of the window and the size of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars 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 do not open will be more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
What do window installers do?
Window installers go to your property to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is complete.
How do you know it's time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
