    How Installing Energy-Efficient Windows in Clayton Saves You Money

    By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:

    • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
    • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Upgrading to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
    • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
    • Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 117 pounds per year on average.

    Estimated Cost of Window Replacement in Clayton

    When looking into window installation, each company offers different services and costs. Let’s look at some typical costs and services.

    How Much Do New Windows Cost?

    Generally, Clayton homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. How much it will cost varies based on several factors, including size, number of windows, type, the location of your home, material and more.

    It’s important to bear in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Clayton homeowners $579+ a year when replacing single-pane windows.

    How much your window installation costs will also vary based on the type of material you choose for the frames. Wood windows are typically the most expensive, but 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 shown to be more efficient.

    What Services do Window Installers Offer?

    In regard to window installations, in general there are two types that your provider will have: full-frame and pocket installations.

    Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations are more time-consuming 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 type of installment if you have any pre-existing rot or water damage.

    If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Clayton, the choice will mostly depend on how much damage there is currently and the age and condition of your existing frames.

    How We Choose the Best Window Installers in Clayton

    EcoWatch reviews differ from other reviews, as we examine these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them using the following methodology:

    Service Area

    This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Clayton so you can find the best window installation company near you.

    Work Quality

    When selecting new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

    Customer Reviews

    We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, warranty, professionalism, cost, quality of parts and more.

    Cost

    This one is a give-and-take: similar to other services, cheap window installers won’t always provide the most quality service. On the other hand, we want to make sure 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. For that reason, window installation companies that offer 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 been in the industry for a while. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

    Clayton, CA Window Replacement FAQs

    How much does window installation cost?

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

    What are the different kinds of windows?

    The most common types of windows for homes include: awning windows, double-hung and single-hung windows, transom windows, picture windows, slider windows, bay windows and casement windows.

    What do window installers do?

    Window installers will do the entire process — from replacing your old windows with brand-new ones to cleaning up after the installation. Additionally, many companies offer window manufacturing, customization and repairs.

    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, 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.

    How long does it typically take to install windows?

    Since a window takes about 30 minutes to install, around 16 windows can be installed in an 8-hour work day.
