    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 Dunkirk Saves You Money

    There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch include the following:

    • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
    • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
    • Save on electricity bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.
    • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.

    Estimated Cost of Window Replacement in Dunkirk

    Windows come in all shapes and sizes, so costs and services will differ considerably. Here are the typical costs and the primary services that you’ll find from window installation companies.

    How Much Do New Windows Cost?

    The typical cost to install a single window is about $600 but can range anywhere from $200 to $1,200. This is because the cost of window installations are based on several factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.

    It’s important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars via returns on your energy bills. Investing in certified energy-efficient windows can save Dunkirk homeowners $386+ a year when replacing single-pane windows.

    We advise getting free quotes from multiple window installation companies to find the right windows and the company that works best for you.

    What Services do Window Installers Offer?

    When considering window replacements, there are generally two types that your provider will offer: full-frame and pocket installations.

    Full-frame installations involve replacing the complete window, including the frame, sill and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage. These installations are more involved and will raise overall costs. A pocket installation involves replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

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

    How We Choose the Best Window Installers in Dunkirk

    In our hunt to find the most reliable, eco-friendly window installers in Dunkirk, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We’ve decided to review the top window installation companies in Dunkirk mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

    Service Area

    Since this is a guide for Dunkirk, we paid more attention to companies that cover the city. There are certainly reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Dunkirk.

    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 featured in our guide to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

    Customer Reviews

    We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including cost, professionalism, quality of parts, quality of installation, warranty and more.

    Cost

    This one is a give-and-take: similar to other services, cheap window installers may not provide the most quality service. Still, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

    Warranty

    Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

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

    Dunkirk, NY Window Replacement FAQs

    How much does a window install cost?

    The national average cost of replacing one window is around $600 but can range between $200 and $1,200, depending on a few different factors. The price is generally dependent on the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

    Which kind of window is the best?

    Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. If you want to be sure you’re getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.

    Can I replace my own windows?

    If you’re handy and have the time and patience to do the job right, you may be able to install your own windows. However, if you don’t have the time or experience, we recommend hiring a professional.

    How often should you replace your windows?

    Windows generally last around 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have them checked by an expert to see if they are in need of a repair or replacement.
