    How Installing Energy-Efficient Windows in Klamath Falls Saves You Money

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

    • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
    • Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient windows can help lower that amount, which helps you save $523 a year on your bills.
    • Reduce your carbon footprint: In Klamath Falls, you can reduce your indirect greenhouse gas emissions by about 271 pounds per year when you switch to energy-efficient windows.
    • Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.

    Estimated Cost of Window Replacement in Klamath Falls

    Each window replacement company offers varying services and has varying costs depending on several factors.

    How Much Do New Windows Cost?

    On average, Klamath Falls homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost sits at about $600. These amounts vary depending on specific characteristics of your installation, such as size, type, the location of your home, material, number of windows and more.

    It’s also worth keeping in mind that energy-efficient windows will cost more initially, but Energy Star predicts that upgrading the windows on your Klamath Falls home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

    Requesting free quotes from several installers is the best way to figure out which one will work best for your budget.

    What Services do Window Installers Offer?

    When it comes to window installations, in general there are two kinds that your provider will offer: full-frame and pocket installations.

    Full-frame installations entail replacing the full window, including the trim, sill and frame. You most likely need a full-frame installation when you want a new style or your window has considerable deterioration. Because these installations are more involved, they will increase the total cost. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

    Your window installation company should be able to help you choose which type of installation you need.

    How We Choose the Best Window Installers in Klamath Falls

    In our search to make your home improvements easier and more eco-friendly in Klamath Falls, EcoWatch examined many companies before deciding on these. We have decided to assess the best window replacement companies in Klamath Falls mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

    Service Area

    Because this is a guide for Klamath Falls, we gave more points to companies that serve the city. There are other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Klamath Falls.

    Work Quality

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

    Customer Reviews

    Customer feedback is another super important review factor. If most customers don’t have good feedback about their experience with a certain window installation company, it won’t be featured on EcoWatch.

    Cost

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

    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

    Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

    Klamath Falls, OR Window Replacement FAQs

    How much does window installation cost?

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

    What are the types of windows?

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

    What services do window installation companies offer?

    Window installation professionals go to your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation is done.

    What time of year is the best time to replace my windows?

    Replacement windows can be installed during any season, but warmer weather is typically better. No matter 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 doesn’t necessarily matter that much. What’s most important is that the weather should be dry.

    Should I replace all my windows at once?

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