    How Installing Energy-Efficient Windows in Kalispell Saves You Money

    There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:

    • 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 money on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
    • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
    • Reduce your carbon footprint: By using less energy once upgrading to energy-efficient windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.

    Estimated Cost of Window Replacement in Kalispell

    Each window installation company offers varying services and has varying prices depending on several factors.

    How Much Do New Windows Cost?

    Though the national average cost to install a single window is around $600, it can range anywhere from $200 to $1,200. How much it will cost depends on several factors, including size, type, number of windows, material, the location of your home and more.

    With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Kalispell homeowners $465+ a year after replacing single-pane windows.

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

    What Services do Window Installers Offer?

    The first thing to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

    A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which raise the total cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails installing a new window within the existing frame. So, instead of tearing 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 replacement company will be able to help you figure out what’s best for your needs. In Kalispell, the decision will mostly be based on how old your windows are and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional evaluate your frames and window sills.

    How We Choose the Best Window Installers in Kalispell

    EcoWatch reviews differ from other reviews because we assess these companies through a sustainability lens. We have reviewed the top window replacement companies in Kalispell primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

    Service Area

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

    Work Quality

    We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer on this list to ensure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

    Customer Reviews

    Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good things to say about their service from a certain company, it won’t be featured on EcoWatch.

    Cost

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

    Warranty

    As discussed, windows are a hefty investment, so you’ll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

    Years of Experience

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

    Kalispell, MT Window Replacement FAQs

    How much does window installation cost?

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

    What kind of window is the most energy-efficient?

    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 installation companies do?

    Window installation professionals will do the entire process — from replacing your old windows with brand-new ones to cleaning up afterward. In addition, some companies offer window manufacturing, customization and repairs.

    When is the best time of year to replace windows?

    Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into your home, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.

    How often do you need to replace your windows?

    Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may need to be replaced.
