    How Installing Energy-Efficient Windows in Loudoun Valley Estates Saves You Money

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

    • Save on electricity bills: Because energy-efficient windows reduce the amount of energy used to heat or cool your home, they can help you save about $353 annually on your energy bills in Loudoun Valley Estates.
    • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
    • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
    • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.

    Estimated Cost of Window Replacement in Loudoun Valley Estates

    Windows come in various shapes and sizes, so costs and services will differ greatly. Here are the typical costs and the primary services that you’ll find from window installation companies.

    How Much Do New Windows Cost?

    Although the national average cost to replace one window is around $600, it can range anywhere from $200 to $1,200. Costs will vary considerably based on the quality of your products, your location, the number of windows you need and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.

    Whether or not you choose 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 $353 a year on your energy bills in Loudoun Valley Estates.

    How much your window installation costs will also vary based on the type of material you choose for the frames. Wood windows are generally the most expensive, though it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

    What Services do Window Installers Offer?

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

    Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations are simpler and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.

    If you’re still trying to decide which kind of installation you should get, you can consult with your provider and get their recommendation. The decision mostly depends on how old the frames are and if there’s any damage present.

    How We Choose the Best Window Installers in Loudoun Valley Estates

    EcoWatch reviews are different from most reviews because we examine these companies through a sustainability lens. We’ve assessed the top window installers in Loudoun Valley Estates mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

    Service Area

    Since this is a guide for Loudoun Valley Estates, we only included companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Loudoun Valley Estates.

    Work Quality

    When installing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

    Customer Reviews

    Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have good feedback about their experience with a certain installer, you won’t see it featured on EcoWatch.

    Cost

    This one is a give-and-take: as with most services, cheap window companies won’t always provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a range of price and financing options so they’re accessible to most homeowners.

    Warranty

    As discussed previously, windows are a sizable investment, so you’ll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and labor 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 installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

    Loudoun Valley Estates, VA Window Replacement FAQs

    What is the average cost to install new windows in a home?

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

    What type of window is the best for energy efficiency?

    A window’s energy efficiency is influenced by several factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

    What do window installers do?

    Window installation professionals travel to your home to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

    How long does it typically take to install windows?

    Each window takes about 30 minutes to install based on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
