    Calculate how much you can expect to pay for window installation and replacement in Kenmore, NY using our customized window cost calculator.

    Estimated Window Cost:
    161 homeowners have requested a free estimate in the last 3 days.

    Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

    How Installing Energy-Efficient Windows in Kenmore Saves You Money

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

    • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
    • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
    • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
    • Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 65 pounds.

    Estimated Cost of Window Replacement in Kenmore

    Each window replacement company provides varying services and has different prices based on several factors.

    How Much Do New Windows Cost?

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

    With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Kenmore homeowners $368+ each year after replacing single-pane windows.

    The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are generally the most expensive, though it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.

    What Services do Window Installers Offer?

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

    A full-frame installation is a total window replacement. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves other materials, like insulation and drip edges, which increase 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 involves installing a new window within the old frame. So, instead of removing the whole window and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

    If you’re unsure which window installation service you should get, your installer should be able to advise you. Typically, the decision depends on 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 Kenmore

    EcoWatch reviews are different from most reviews, as we assess these companies through a sustainability lens. We’ve reviewed the best window installation companies in Kenmore mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can reduce your energy 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 Kenmore so you can find a quality window installation company near you.

    Work Quality

    When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand of window you choose. 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

    Customer feedback is another very important review factor. If the majority of customers don’t have positive feedback about their experience with a certain installer, you won’t see it featured on EcoWatch.

    Cost

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

    Warranty

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

    Years of Experience

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

    Kenmore, NY Window Replacement FAQs

    What is the average cost to install new windows?

    The average cost to replace one window ranges from $450 to $650. There are many factors that affect the price, including the number of windows, your property’s location, the materials used in designing the windows, how energy-efficient the windows are, styles and sizes of windows and local labor costs.

    What are the most common types of replacement windows?

    There are several different kinds of windows you can get for your home, including slider windows, double-hung and single-hung windows, transom windows, casement windows, bay windows, picture windows and awning windows.

    Can you replace your own windows?

    Although it is possible to install your own windows, doing so is time-consuming and requires a lot of handiness. Using a window replacement company can help ensure that the installation is done properly and that you won’t have to spend the time and effort to do it yourself.

    How long does it generally take to install windows?

    Since the average installation time of a window is 30 minutes, around 16 windows can be installed in an 8-hour work day.
