Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house’s efficiency can also have a big impact on home energy conservation. Traditional, outdated windows can cost you in power bills. As a matter of fact, the Department of Energy estimates that about 30% of your house’s heat or cool air could be lost through your windows.
Installing new, efficient windows on your home can help you save money each month on your electric bills — and you can help the environment, too.
So if you’re constructing a new home, renovating or changing out old windows in Wood River, this is the best place to get started.

How Installing Energy-Efficient Windows in Wood River Saves You Money
There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Save on power bills: Because energy-efficient windows decrease the amount of energy used to heat or cool your home, they can help you save about $313 annually on your energy bills in Wood River.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
- Reduce your carbon footprint: In Wood River, you can lower your indirect greenhouse gas emissions by about 642 pounds per year once you install energy-efficient windows.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in Wood River
When considering window installation, each company provides varying services and costs. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
According to our research, the national average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. Costs will vary significantly based on the number of windows you need, the current condition of your home, your location and the quality of your products. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. These extra services will increase your overall project costs.
Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 per 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.
We recommend getting free quotes from several window installation companies to find the one that works best for your budget.
What Services do Window Installers Offer?
When considering window replacements, in general there are two kinds that your installer will have: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which raise 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 (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.
If you’re still trying to decide which kind of installation you should get, you can consult with your provider and get their recommendation. The decision mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Wood River
In our hunt to find the most reliable, eco-friendly window installers in Wood River, the EcoWatch Reviews team evaluated dozens of companies before landing on these. Along with energy efficiency, we assessed several window installers in Wood River and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve the Wood River area so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and variety 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 higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of parts, cost, warranty, professionalism, quality of installation and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a serious investment, so you’ll want to make sure that investment is protected. Window installation companies that have 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 experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Wood River, IL Window Replacement FAQs
How much should window installation cost?
The national average cost of installing a single window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is generally dependent on 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 is the best?
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’re getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
Do you really need to use a window installation company?
Unless you’re handy and have the tools needed to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and safer option.
What time of year is a good time to replace my windows?
Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside doesn’t necessarily matter that much. What’s more important than the temperature is that the weather should be dry.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on your energy bills, replacing all of the windows together is the only way to see a noticeable difference. However, if you have just a few windows that are damaged or drafty, you can replace just those.
