    How Installing Energy-Efficient Windows in Decatur Saves You Money

    Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to consider making the switch:

    • Save on power bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you need less energy.
    • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
    • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
    • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

    Estimated Cost of Window Replacement in Decatur

    When researching window installation, each company offers different services and prices. Let’s take a look at some typical costs and services.

    How Much Do New Windows Cost?

    According to our research, the national average cost of installing a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost is based on several factors, like number of windows, material, size, the location of your home, type and more.

    It’s also worth noting that energy-efficient windows will typically cost more initially, but Energy Star predicts that switching out the windows on your Decatur home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

    Getting free quotes from several installers is the best way to figure out which one will work best for your budget.

    What Services do Window Installers Offer?

    Generally, there are two types of window installation services you can get: full-frame and pocket installations.

    A full-frame installation is a replacement of the full window. It involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, such as insulation and drip edges, which raise 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 entails installing a new window without replacing the frame. So, instead of removing the whole window and rebuilding it, the installer 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 to get, you can ask your installer and get their recommendation. The choice mostly is influenced by how old the frames are and if there’s any damage.

    How We Choose the Best Window Installers in Decatur

    In our search to make your home improvements easier and more eco-friendly in Decatur, EcoWatch chose the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated several window installers in Decatur 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 the Decatur area so you can find a quality window installation company near you.

    Work Quality

    We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included on this list to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

    Customer Reviews

    We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including warranty, professionalism, quality of parts, cost, quality of installation and more.

    Cost

    Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we gave 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. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

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

    Decatur, IL Window Replacement FAQs

    What is the average cost to install new windows?

    The national average cost to replace one window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is typically dependent on 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 a decent amount of money a year in energy bills.

    What are the different types of windows?

    The most common types of windows for homes are casement windows, double-hung and single-hung windows, slider windows, bay windows, picture windows, awning windows and transom windows.

    Can you install your own windows?

    Although you can install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window installation company can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

    When is the best time of year to replace 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 make sure 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 more important than the temperature is that the weather should be dry.

    How do you know it’s time to replace your windows?

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