How Installing Energy-Efficient Windows in South Moline Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by about 478 pounds.
- Save money on power bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll require less energy to heat or cool your house.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in South Moline
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?
Although the average cost to replace one window is about $600, it can range from $200 to $1,200. How much it will cost is based on several factors, like number of windows, material, the location of your home, size, type and more.
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 per year when you install single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your savings will 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 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 with 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?
When considering window installations, there are generally two types that your provider will have: 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 can also involve extra materials, including insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves replacing a window without replacing the frame. So, instead of tearing out the whole unit and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you’re hiring a reputable window installation company, your company will be able to recommend the best type for your project. In South Moline, the choice will mostly be influenced by the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in South Moline
In our hunt to find the most reliable, eco-friendly window installers in South Moline, EcoWatch examined dozens of companies before deciding on these. We’ve evaluated the top window installation companies in South Moline mostly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve South Moline 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 you choose. 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 trends in recent online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including quality of parts, quality of installation, professionalism, cost, warranty and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that have 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 installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
South Moline, IL Window Replacement FAQs
How much should window installation cost?
The average cost to install a single window can range from $450 to $650. There are several factors that influence how much it costs, such as how energy-efficient the windows are, local labor costs, your property’s location, styles and sizes of windows, the number of windows and the materials used in designing the windows.
What are the types of windows?
The most common kinds of windows for homes are awning windows, transom windows, picture windows, bay windows, casement windows, double-hung and single-hung windows and slider windows.
Can I replace my own windows?
Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window replacement company can help ensure that the installation is done properly and that you won’t have to spend the time and effort to do it yourself.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.
When is it time to replace your windows?
Windows usually have a lifespan of around 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have an expert take a look at them to determine if they are in need of a repair or replacement.
