Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

A guide on the top window replacement companies in Mount Kisco may not seem like the most interesting article on EcoWatch, but trust us, windows have more of an impact on your life than you might realize. If you have traditional, outdated windows, your AC or heating system could be working overtime to heat or cool your house. This means spending more on power bills.

That’s also bad news for the environment because the additional energy required by leaky windows increases your carbon footprint.

Unlike other review sites, EcoWatch ranks window replacement companies on energy efficiency while also balancing cost, customer satisfaction and service area.

    How Installing Energy-Efficient Windows in Mount Kisco Saves You Money

    Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to think about making the switch:

    • Save on energy bills: Since energy-efficient windows lower the amount of energy needed to heat or cool your home, they can help you save about $331 annually on your energy bills in Mount Kisco.
    • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
    • Decrease your carbon footprint: By using less energy once upgrading 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    • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.

    Estimated Cost of Window Replacement in Mount Kisco

    Each window installer provides varying services and has varying prices depending on several factors.

    How Much Do New Windows Cost?

    According to our market research, the national average cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. How much it will cost depends on several factors, like size, material, the location of your home, type, number of windows and more.

    Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

    We recommend requesting free quotes from several window installation companies to find the one that works best for your budget.

    What Services do Window Installers Offer?

    When considering window installations, in general there are two kinds that your installer will have: full-frame and pocket installations.

    Full-frame installations involve replacing the full window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has noticeable damage. These installations are more involved and will raise 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 will be able to help you decide what’s best for your needs. In Mount Kisco, the decision will mostly depend on the age of your home and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional assess your frames and window sills.

    How We Choose the Best Window Installers in Mount Kisco

    EcoWatch differs from most reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and ranked them using the following methodology:

    Service Area

    This one is self-explanatory, but we’ve chosen to highlight window installers that serve Mount Kisco so you can find a quality window installation company near you.

    Work Quality

    When picking new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

    Customer Reviews

    Customer feedback is another super important review factor. If most customers don’t have nice things to say about their experience with 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

    Protecting your investment in new windows is important. For that reason, window installation companies that give you 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 quite some time. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

    Mount Kisco, NY Window Replacement FAQs

    How much should a window install cost?

    The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is often dependent on the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

    Which type of window should I get?

    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 cover the entire process — from replacing old windows with new ones to cleaning up after the installation. Additionally, a lot of companies offer window manufacturing, customization and repairs.

    How long does it typically take to install windows?

    Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
