Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home's energy efficiency can also have a considerable impact on home energy conservation. According to the Department of Energy, heat or cool air lost through old or damaged windows could represent 25-30% of residential energy climate control use.
Installing new, efficient windows on your property can help you save money every month on your power bills — and you can help the environment, too.
Efficient windows are particularly important in Rock Island, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $323 per year.

How Installing Energy-Efficient Windows in Rock Island Saves You Money
When you switch to energy-efficient windows, you may see some perks, such as:
- Save money on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
- Better temperature control in your home: Residing in a very cold place like Rock Island often means needing your heater to keep your house cool. Energy-efficient windows can cut back on how much heat is lost through your windows when heating your home.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient 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 Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way.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.
- 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 harmful UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Rock Island
When looking into window installation, each company provides different services and prices. Let's go over some average costs and services.
How Much Do New Windows Cost?
Even though the typical of replacing a single window is around $600, it can range from $200 to $1,200. This is because the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.
It's important to bear in mind that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Rock Island homeowners $323+ a year when replacing single-pane windows.
Getting free quotes from several companies is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first thing to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?
Full-frame installations entail replacing the full window, including the frame, sill and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage or rot. Because full-frame installations are more involved, they will increase overall costs. A pocket installation involves installing a new window without replacing the frame. This means instead of taking out the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still debating which type of installation you need, you can ask your installer and get their advice. The choice mostly depends on the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Rock Island
The EcoWatch Reviews team is different from other reviewers, as we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Rock Island and ranked them based on the following methodology:
Service Area
Because this is a guide for Rock Island, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Rock Island.
Work Quality
When it comes to 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 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 patterns in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including professionalism, quality of parts, warranty, quality of installation, cost and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like 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, windows are a significant investment, so you'll want to make sure that investment is well protected. Window installation companies that offer 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 a while. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
