    How Installing Energy-Efficient Windows in New Milford Saves You Money

    By switching to energy-efficient windows, you can enjoy several benefits, such as:

    • Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
    • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
    • Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.
    • Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.

    Estimated Cost of Window Replacement in New Milford

    Let’s take a look at the cost of installing new windows and the types of services you may need for your home.

    How Much Do New Windows Cost?

    Generally, homeowners in New Milford can expect that most replacement window installations will cost between $250 and $1,200, with the average cost at about $600. But costs vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which carry a higher price tag.

    It’s also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star predicts that switching out the windows on your New Milford home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

    Costs will also vary based on the material you pick for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

    What Services do Window Installers Offer?

    There are generally two kinds of window replacement services: full-frame and pocket installations.

    Full-frame installations entail replacing the total window, including the trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has noticeable rot. Because these installations are more involved, they will increase the total cost. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler 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.

    If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In New Milford, the choice will mostly be influenced by the efficiency of your home and how old your existing frames are.

    How We Choose the Best Window Installers in New Milford

    In our search to make your home improvements easier and more eco-friendly in New Milford, the EcoWatch team evaluated many companies before settling on these. We’ve evaluated the top window installers in New Milford primarily based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can cut 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 self-explanatory, but we’ve chosen to highlight window installers that serve New Milford so you can find the best window installation company near you.

    Work Quality

    We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company 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 trends in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, warranty, cost, quality of installation, professionalism and more.

    Cost

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

    Warranty

    Protecting your investment in new windows is important. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

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

    New Milford, CT Window Replacement FAQs

    What is the average cost to replace windows?

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

    What kind of window is the best for energy efficiency?

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

    What do window installers do?

    Window installation professionals go to your home to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.

    How often do you need to replace windows?

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