        How Installing Energy-Efficient Windows in Watertown Saves You Money

        When you switch to energy-efficient windows, you may see several perks, such as:

        • Reduce your carbon footprint: In Watertown, you can lower your indirect greenhouse gas emissions by about 147 pounds per year after you upgrade to energy-efficient windows.
        • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
        • Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its value.
        • Save money on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.

        Estimated Cost of Window Replacement in Watertown

        Let’s take a look at the cost of installing new windows and the kinds of services offered by installers.

        How Much Do New Windows Cost?

        Typically, homeowners in Watertown can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. These numbers vary depending on specific characteristics of your installation, like the location of your home, material, type, size, number of windows and more.

        It’s important to note that windows with higher efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Watertown homeowners $486+ a year when replacing single-pane windows.

        How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.

        What Services do Window Installers Offer?

        In general, there are two kinds of window installation services companies provide: full-frame and pocket installations.

        Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of deterioration. With this service, your professionals will replace the whole window, including the frame, sill and trim. A pocket installation involves installing a new window within the existing frame. So, instead of taking out the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

        Your window replacement company will be able to help you understand what’s best for your needs. In Watertown, 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 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 Watertown

        The EcoWatch Reviews team is different from other reviewers since we assess these companies through a sustainability lens. Along with energy efficiency, we reviewed several window installers in Watertown and assigned rankings using the following methodology:

        Service Area

        Since this is a guide for Watertown, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Watertown.

        Work Quality

        We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company featured on this list to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

        Customer Reviews

        We analyzed patterns in recent customer feedback 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 most other categories, including quality of parts, quality of installation, professionalism, cost, warranty and more.

        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 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 that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

        Years of Experience

        Lastly, we like to see companies that have been in the industry for a while. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

        Watertown, CT Window Replacement FAQs

        How much should window installation cost?

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

        Which kind of window should I get?

        A window’s energy efficiency is influenced by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

        When do I need to use a window installation company?

        You should use a window installation company whenever you need to replace your windows. Installing windows is a complicated process that can be difficult to do on your own, so it’s best left to the professionals.

        How often should you replace windows?

        Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
