How Installing Energy-Efficient Windows in Fulton Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
- Save on electricity bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- More efficient energy use in your home: Because the winters can get very cold in Fulton, homeowners often rely on their heater during that time. Energy-efficient windows lower how much heat is lost through your windows, making it easier to keep your house warm.
Estimated Cost of Window Replacement in Fulton
When researching window installation, each company provides different services and prices. Let's look at some average costs and services.
How Much Do New Windows Cost?
Typically, homeowners in Fulton can expect that most window installations will range from $250 to $1,200, with the most common installations sitting at about $600. But costs will vary significantly depending on the quality of your products, your location, the number of windows you need and the current condition of your home. A lot of window companies also offer door installations and other add-ons like coating, baths, shutters and more. These extra services will increase overall project costs.
Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material you choose for your window frames. Aluminum frames are the least expensive. 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 from 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 kinds of window installation services companies provide: full-frame and pocket installations.
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 extra materials, such as insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you should opt for 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 Fulton
In our search to find the most reliable, eco-friendly window installers in Fulton, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated each installer and ranked them 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 choosing new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the type of window you get. 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 determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of installation, quality of parts, warranty, cost, professionalism and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try 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 previously, windows are a significant investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. 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.
Fulton, IL Window Replacement FAQs
How much does window installation cost?
The average cost to install a window can range from $450 to $650. There are several factors that affect the cost, such as your property's location, styles and sizes of windows, local labor costs, the materials used in designing the windows, the number of windows and how energy-efficient the windows are.
Which kind of window should I get?
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're getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
If you're handy and have experience with installing a replacement window, it's possible to install your own windows. However, if you don't have the time or know-how, we recommend hiring a professional.
What time of year is a good time to replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the home, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.
