    How Installing Energy-Efficient Windows in Freeport Saves You Money

    Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more details about how switching out your windows could help you:

    • Decrease your carbon footprint: In Freeport, you can cut your indirect greenhouse gas emissions by about 449 pounds per year when you install energy-efficient windows.
    • Save on power bills: Because energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save around $326 annually on your energy bills in Freeport.
    • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way.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 from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.

    Estimated Cost of Window Replacement in Freeport

    Windows come in varying styles, shapes and purposes, so costs and services will differ considerably based on your project. Below, we detail the typical cost and services that you’ll find from window replacement companies.

    How Much Do New Windows Cost?

    The national average cost to replace one window is about $600 but can range from $200 to $1,200. This is due to the fact that the cost of window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

    With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Freeport homeowners $326+ a year after replacing single-pane windows.

    Asking for free quotes from multiple installers is the best way to find out which one will work best for your budget.

    What Services do Window Installers Offer?

    The first step when planning a window installation is to clarify whether you should get a full-frame or pocket installation.

    A full-frame installation is a replacement of the total window. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which raise the total cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.

    If you’re not sure which kind of window installation service you should get, your installer should be able to assist you. Typically, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

    How We Choose the Best Window Installers in Freeport

    In our search to make your home improvements easier and more eco-friendly in Freeport, EcoWatch assessed many companies before deciding on these. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:

    Service Area

    This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Freeport area so you can find a quality window installation company near you.

    Work Quality

    When installing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you choose. We do rate window installers higher 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 most customers don’t have nice feedback about their experience with a certain window installation company, you won’t see it featured on EcoWatch.

    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

    Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

    Because of Freeport’s climate, homeowners need to be wary of low efficiency, water damage and rot. 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

    What is the average cost to install new windows?

    The average cost to install a window can range from $450 to $650. There are several factors that affect the cost, including your property’s location, how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, the number of windows and local labor costs.

    Which kind of window should I get?

    Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. If you want to be sure you’ll get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.

    Do I really need to use a window installation company?

    You should use a window installation professional whenever you want new windows. Installing windows is a involved process that can be difficult to do on your own, so it’s best left to the professionals.

    How often should you replace windows?

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

    Should I replace all my windows at the same time?

    If your windows are more than 20 years old, it’s most likely time to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
