    How Installing Energy-Efficient Windows in Downers Grove Saves You Money

    By switching to energy-efficient windows, you can enjoy several benefits, such as:

    • Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
    • Reduce your carbon footprint: In Downers Grove, you can reduce your indirect greenhouse gas emissions by about 449 pounds per year after you switch to energy-efficient windows.
    • Save money on electricity bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save around $300 annually on your energy bills in Downers Grove.
    • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

    Estimated Cost of Window Replacement in Downers Grove

    Windows come in varying styles, purposes and shapes, so costs and services will vary remarkably depending on your project. Below, we describe the average cost and services that you’ll find from window installation companies.

    How Much Do New Windows Cost?

    On average, Downers Grove homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. This is because of the fact that window installations are based on several factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.

    It’s important to remember that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Downers Grove homeowners $300+ a year when replacing single-pane windows.

    Getting free quotes from several companies is the best way to figure out which one is right for you.

    What Services do Window Installers Offer?

    In general, there are two kinds of window replacement services companies provide: full-frame and pocket installations.

    Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations are simpler and won’t carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.

    Your window replacement company should be able to help you choose what’s best for your needs. In Downers Grove, the decision will mostly be based on how old your windows are and if there’s any moisture damage. Wood can decay if not properly maintained over the years, so it’s good to have a professional assess your frames and window sills.

    How We Choose the Best Window Installers in Downers Grove

    EcoWatch reviews are different from other reviews because we look at these companies through a sustainability lens. We have decided to review the top window replacement companies in Downers Grove primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

    Service Area

    Since this is a guide for Downers Grove, we only included companies that provide services to the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Downers Grove.

    Work Quality

    When installing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

    Customer Reviews

    Customer feedback is another super important review factor. If the majority of customers don’t have nice feedback about their experience with a certain installer, it won’t be featured on EcoWatch.

    Cost

    This one is a give-and-take: similar to most services, cheap window companies may not provide the highest quality service. On the other hand, we want to make sure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

    Warranty

    Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) 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 experience earn higher rankings by our standards. We like to see at least ten years of experience.

    Downers Grove, IL Window Replacement FAQs

    What is the average cost to install windows in a home?

    The average cost to replace a window ranges between $450 and $650. There are several factors that influence the price, which include the number of windows, local labor costs, how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows and your property’s location.

    What kind of window is the most energy-efficient?

    Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you’re getting the most energy-efficient windows, look for models that have the blue Energy Star certification — this means they’re certified energy-efficient by the U.S. Department of Energy.

    What do window installation companies do?

    Window installation professionals cover the entire process — from replacing old windows with new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.

    What time of year should I 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 the home, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.

    Should I replace all my windows at once?

    If you want to get more efficient windows and save money on energy costs, replacing all the windows together is the only way to gain that benefit. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
