How Installing Energy-Efficient Windows in Rock Island Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to take the plunge and make the switch:
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Switching to energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: In Rock Island, you can cut your indirect greenhouse gas emissions by about 478 pounds per year once you upgrade to energy-efficient windows.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
Estimated Cost of Window Replacement in Rock Island
When looking into window installation, each company offers varying services and prices. Let's go over some average costs and services.
How Much Do New Windows Cost?
Generally, Rock Island homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost is at about $600. These figures vary based on specific characteristics of your installation, including the location of your home, material, size, number of windows, type and more.
It's important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Rock Island homeowners $323+ a year when replacing single-pane windows.
Costs will also vary based on the material you pick for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first question to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the total window. This service involves removing 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 overall 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. A pocket installation entails replacing a window without replacing the frame. This means instead of taking out the whole window and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window replacement company should be able to help you decide what's best for your needs. In Rock Island, the decision will mostly be based on the age of your home and if there's any damage. Wood can decay if not maintained properly over the years, so it's good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Rock Island
In our hunt to find the most reliable, eco-friendly window installers in Rock Island, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed each installer and ranked them based on the following methodology:
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 right window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand you get. We do rate window installers higher 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. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including cost, professionalism, quality of installation, warranty, quality of parts and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing providers' prices, we gave higher scores 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 have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Rock Island's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Rock Island window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Rock Island, IL Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, depending on several factors. The price is usually influenced by the location of your property, the size of the window and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What type of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have 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?
Even though you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window installation company can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does window installation generally take?
Each window takes around 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
What time of year is the best 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 ensure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
