    How Installing Energy-Efficient Windows in Freeport Saves You Money

    When you upgrade to energy-efficient windows, you may see some perks, such as:

    • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.
    • Save money on power bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save about $326 annually on your energy bills in Freeport.
    • 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 Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
    • Protect your valuables: Many energy-efficient 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 Freeport

    Let’s go over the cost of window replacement and the kinds of services you may need for your home.

    How Much Do New Windows Cost?

    Generally, homeowners in Freeport can expect that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. These figures are based on the specifics of your installation, including type, number of windows, material, size, the location of your home and more.

    Whether or not you want energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $326 a year on your energy bills in Freeport.

    Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. 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 using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive 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 thing to ask yourself when considering a window replacement is: Should you get a full-frame installation or a pocket installation?

    A full-frame installation is a total window replacement. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves installing a new window without replacing the frame. So, instead of removing the whole unit and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

    If you’re still trying to decide which kind of installation you need, you can ask your provider and get their recommendation. The choice mostly is influenced by how old the frames are and if there’s any damage present.

    How We Choose the Best Window Installers in Freeport

    EcoWatch reviews differ from other reviews, as we evaluate these companies through a sustainability lens. We’ve evaluated the best window installation companies in Freeport primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

    Service Area

    Because this is a guide for Freeport, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Freeport.

    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 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

    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 reflects the quality of services across nearly every category, including professionalism, cost, quality of installation, quality of parts, warranty and more.

    Cost

    This one is a give-and-take: as with other services, cheap window installers won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

    Warranty

    As discussed previously, windows are a hefty investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

    Due to Freeport’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of Freeport window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

    Freeport, IL Window Replacement FAQs

    How much should window installation cost?

    The national average cost of replacing a window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is usually influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

    What kind of window is the best for energy efficiency?

    A window’s energy efficiency depends on a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

    When do I need to use a window installation company?

    Unless you have home repair skills and have the time to replace your own windows, we recommend hiring the pros. The process of installing windows is complex and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer option.

    When is it time to replace your windows?

    Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.

    Should I replace all my windows at once?

    If your windows are more than 20 years old, you most likely need to replace all of them. At that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
