How Installing Energy-Efficient Windows in Sullivan Saves You Money
When you switch to energy-efficient windows, you may see several benefits, including:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
- More efficient energy usage in your household: Because the winters can get very cold in Sullivan, homeowners usually rely on their heater a lot. Energy-efficient windows decrease the amount of heat that is lost through your windows, making it easier to keep your house warm.
- Save money on energy bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll require less energy to heat or cool your house.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in Sullivan
When considering window installation, each company offers varying services and prices. Let's take a look at some average costs and services.
How Much Do New Windows Cost?
According to our research, the national average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. Costs will vary significantly based on the current condition of your home, the quality of your products, the number of windows you need and your location. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase overall project costs.
With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Sullivan homeowners $311+ a year after replacing single-pane windows.
Costs will also vary depending on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
In general, there are two types of window installation services companies provide: full-frame and pocket installations.
Full-frame installations are usually recommended when you want a new style or your window has a lot of rot or deterioration. With this service, your professionals will replace the full window, including the sill, frame and trim. A pocket installation entails installing a new window without replacing the frame. This means instead of tearing out the whole window and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installer can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Sullivan
In our search to find the most reliable, eco-friendly window installers in Sullivan, the EcoWatch Reviews team examined many companies before settling on these. We've assessed the best window installation companies in Sullivan mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
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 best window installation company near you.
Work Quality
When installing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, quality of installation, cost, professionalism, quality of parts and more.
Cost
This one is a give-and-take: as with other services, cheap window installers may not provide the most quality service. Still, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, 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 proven track record in the industry. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Sullivan, IL Window Replacement FAQs
What is the average cost to install new windows in a home?
The typical cost to install a window can range from $450 to $650. There are many factors that affect how much it costs, including the materials used in designing the windows, local labor costs, styles and sizes of windows, how energy-efficient the windows are, your property's location and the number of windows.
Which kind of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't 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.
Do you really have to use a window installation company?
Unless you're handy and have the time to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.
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, they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
