    How Installing Energy-Efficient Windows in St. Peters Saves You Money

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

    • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In St. Peters, that’s about 763 pounds per year on average.
    • Save money on energy bills: Since energy-efficient windows decrease the amount of energy needed to heat or cool your home, they can help you save about $382 annually on your energy bills in St. Peters.
    • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
    • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.

    Estimated Cost of Window Replacement in St. Peters

    Each window installation company offers various services and has different costs based on several factors.

    How Much Do New Windows Cost?

    Typically, homeowners in St. Peters can expect that most replacement window installations will range from $250 to $1,200, with the average cost at about $600. This is because of 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 install, as well as the location of your property.

    Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $382 a year on your energy bills in St. Peters.

    We recommend requesting free quotes from multiple window installation companies to find the one that works best for your budget.

    What Services do Window Installers Offer?

    There are generally two kinds of window replacement services: full-frame and pocket installations.

    A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, like 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 within the existing frame. This means instead of tearing out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

    Your window installation company can advise you on the best type for your project. In St. Peters, the choice will mostly be based on the efficiency of your home and how old your existing frames are.

    How We Choose the Best Window Installers in St. Peters

    EcoWatch reviews are different from other reviews, as we look at these companies through a sustainability lens. We have decided to assess the best window replacement companies in St. Peters mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your electricity 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 St. Peters, we gave more points to companies that cover the city. There are other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in St. Peters.

    Work Quality

    We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to make sure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

    Customer Reviews

    We analyzed patterns in recent customer feedback 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 indicates the quality of services across most other categories, including quality of parts, quality of installation, professionalism, cost, warranty and more.

    Cost

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

    Years of Experience

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

    St. Peters, MO Window Replacement FAQs

    How much does window installation cost?

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

    Which kind of window is the best?

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

    Can you replace your own windows?

    If you’re handy and have experience with similar home improvement projects, you may be able to install your own windows. However, if you don’t have the time or experience, we recommend getting a professional to do it for you.

    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 need to be replaced.
