    How Installing Energy-Efficient Windows in St. Ann 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 ways upgrading your windows could help you:

    • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
    • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
    • Save on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
    • Decrease your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.

    Estimated Cost of Window Replacement in St. Ann

    Windows come in various shapes, styles and purposes, so costs and services will vary considerably depending on several factors. Below, we go over the typical cost and services that you can get from window installation companies.

    How Much Do New Windows Cost?

    Typically, St. Ann homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. This is because the cost of window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

    Whether or not you want to install energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $376 a year on your energy bills in St. Ann.

    We recommend requesting free quotes from several window companies to find the right windows and the company that works best for you.

    What Services do Window Installers Offer?

    The first step when considering a replacement is to figure out whether you should get a full-frame or pocket installation.

    A full-frame installation replaces the full window, such as the sill, frame, trim and the window panes. Because this type of installation requires more time, it will cost more than a pocket installation. Pocket installations (or retrofits) involve replacing a window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

    If you’re still trying to decide which type of installation to get, you can talk to your installer and get their recommendation. The choice mostly depends on the age of your window frames and if there’s any damage present.

    How We Choose the Best Window Installers in St. Ann

    EcoWatch is different from other reviewers since we assess these companies through a sustainability lens. We’ve assessed the best window replacement companies in St. Ann mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your energy 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. Ann, 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 St. Ann.

    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 in our guide to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

    Customer Reviews

    Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have good feedback about their experience with a certain company, it won’t be featured on EcoWatch.

    Cost

    This one is a give-and-take: as with other services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer 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 give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

    Years of Experience

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

    St. Ann, MO Window Replacement FAQs

    How much does window installation cost?

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

    What type of window is the best for energy efficiency?

    Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. 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.

    When do I have to use a window installation company?

    Unless you’re handy and have all the necessary tools to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to save money by doing it yourself, hiring a professional is a faster, more efficient and much safer option.

    When is the best time of year to replace windows?

    Although you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, it shouldn’t be raining, as rain can make the installation more difficult.

    Should I replace all my windows at the same time?

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