    How Installing Energy-Efficient Windows in Affton Saves You Money

    There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:

    • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
    • Decrease your carbon footprint: In Affton, you can reduce your indirect greenhouse gas emissions by about 763 pounds per year after you install energy-efficient windows.
    • Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that amount, which helps you save $376 a year on your bills.
    • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.

    Estimated Cost of Window Replacement in Affton

    Windows come in various shapes and sizes, so costs and services will vary considerably. Here are the typical costs and the primary services that you’ll find from the average window installation company.

    How Much Do New Windows Cost?

    Though the typical cost of replacing a single window is around $600, it can range from $200 to $1,200. But costs will vary considerably depending on your location, the number of windows you need, the quality of your products and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase overall project costs.

    Whether or not you choose energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $376 a year on your energy bills in Affton.

    Something else that influences the total cost is the material of the frame you choose. Aluminum frames are generally the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

    What Services do Window Installers Offer?

    The first thing to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?

    Full-frame installations entail replacing the complete window, including the trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has significant damage. These installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are on the simpler end and will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

    Your window installation company will be able to help you figure out what’s best for your needs. In Affton, the decision will mostly depend on the age of your home and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional assess your frames and window sills.

    How We Choose the Best Window Installers in Affton

    EcoWatch reviews are different from other reviews because we look at these companies through a sustainability lens. We’ve evaluated the top window installation companies in Affton primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

    Service Area

    Since this is a guide for Affton, we gave more points to companies that cover the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Affton.

    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 featured on this list to ensure its contractors are well-qualified and that the company has gotten tons 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 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 nearly every category, including quality of installation, cost, quality of parts, warranty, professionalism and more.

    Cost

    This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.

    Warranty

    Protecting your investment in new windows is important. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

    Years of Experience

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

    Affton, MO Window Replacement FAQs

    What is the average cost to install new windows?

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

    What kind of window is the most energy-efficient?

    Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open are more efficient than windows that do. If you want to be sure you’ll have 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 a professional installer. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and much safer option.

    How often do you need to replace windows?

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