    How Installing Energy-Efficient Windows in Saratoga Saves You Money

    Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here's more information on how upgrading your windows could benefit you:

    • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
    • Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 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.
    • Decrease your carbon footprint: By using less energy once you switch to Energy Star certified windows, you’ll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
    • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if your home is on the older side.

    Estimated Cost of Window Replacement in Saratoga

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

    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. But costs will vary significantly depending on the quality of your products, your location, the current condition of your home and the number of windows you need. Many window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.

    With windows, efficiency is one of the most important factors for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Saratoga homeowners $562+ a year after replacing single-pane windows.

    Something else that influences the overall cost is the material you choose for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

    What Services do Window Installers Offer?

    In regard to window replacements, there are generally two types that your installer will have: full-frame and pocket installations.

    A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, such as insulation and drip edges, which raise the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails replacing a window without removing the complete frame, which tends to be less expensive than a full-frame installation.

    If you’re unsure which kind of window installation service you should get, your installer should be able to advise you. Typically, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

    How We Choose the Best Window Installers in Saratoga

    In our hunt to find the most reliable, eco-friendly window installers in Saratoga, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. We’ve evaluated the top window installers in Saratoga mostly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

    Service Area

    This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the right window installation company near you.

    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 company on this list to make sure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

    Customer Reviews

    We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including professionalism, quality of parts, warranty, cost, quality of installation and more.

    Cost

    Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

    Warranty

    Protecting your investment in new windows is important. That’s why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

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

    Saratoga, CA Window Replacement FAQs

    What is the typical cost to install windows in a home?

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

    Which type of window is the best?

    A window’s energy efficiency is influenced by a number of factors, such as the quality of the installation and the kind of window. 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 installation companies do?

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

    What time of year should I replace my windows?

    Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside isn’t necessarily a big factor. Most importantly, the weather should be dry.

    Should I replace my windows all at once?

    If you’re upgrading your windows to save on your energy bills, replacing all of the windows together is the only way to gain that benefit. However, if you have just one or two windows that are broken or leaky, you can replace just those.
