    How Installing Energy-Efficient Windows in Sterling Saves You Money

    When you upgrade to energy-efficient windows, you may see some benefits, including:

    • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
    • Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
    • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
    • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Sterling, that’s about 376 pounds per year on average.

    Estimated Cost of Window Replacement in Sterling

    Let’s go over the cost of replacing your windows and the kinds of services offered by installers.

    How Much Do New Windows Cost?

    The national average cost to install one window is about $600 but can range anywhere from $200 to $1,200. How much it will cost varies based on several factors, such as material, type, number of windows, the location of your home, size and more.

    With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Sterling homeowners $353+ each year after replacing single-pane windows.

    The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

    What Services do Window Installers Offer?

    The first thing to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?

    Full-frame installations involve replacing the complete window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable damage or rot. Because these installations are more involved, they will increase overall costs. A pocket installation involves replacing a window without replacing the frame. This means instead of taking out the whole unit and rebuilding it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

    Your window installation company should be able to help you choose what’s best for your needs. In Sterling, 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 good to have a professional evaluate your frames and window sills.

    How We Choose the Best Window Installers in Sterling

    In our search to make your home improvements easier and more eco-friendly in Sterling, the EcoWatch Reviews team evaluated dozens of companies before landing on these. We’ve assessed the best window installers in Sterling primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

    Service Area

    Because this is a guide for Sterling, we paid more attention 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 Sterling.

    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 featured in our guide to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

    Customer Reviews

    Customer feedback is another very important review factor. If most customers don’t have positive things to say about their service from a certain window installation company, it won’t be featured on EcoWatch.

    Cost

    This one is a give-and-take: as with other services, cheap window installation companies won’t always provide the highest quality service. On the other hand, we want to make sure 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 to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

    Years of Experience

    Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

    Sterling, VA Window Replacement FAQs

    How much does window installation cost?

    The typical cost of installing a single window can range between $450 and $650. There are several factors that influence the price, such as your property’s location, styles and sizes of windows, the number of windows, how energy-efficient the windows are, local labor costs and the materials used in designing the windows.

    Which type of window is the best?

    A window’s energy efficiency is affected by several factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

    Do I really have to use a window installation company?

    Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring a professional. The process of installing windows is complicated and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.

    Should I replace all my windows at the same time?

    If you’re upgrading your windows because of energy-efficiency, replacing all your windows at the same time is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are damaged or leaky, you can replace just those.
