    How Installing Energy-Efficient Windows in Cromwell Saves You Money

    By switching to energy-efficient windows, you can benefit in several ways, including:

    • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
    • Save on electricity bills: Because energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $403 annually on your energy bills in Cromwell.
    • Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 147 pounds per year on average.
    • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

    Estimated Cost of Window Replacement in Cromwell

    Each window installation company provides various services and has varying costs depending on a few factors.

    How Much Do New Windows Cost?

    The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. This is because of the fact that the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.

    It’s also worth keeping in mind that energy-efficient windows will cost more upfront, but Energy Star estimates that upgrading the windows on your Cromwell home can mean 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 switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

    Getting free quotes from several companies is the best way to find out which one will work best for your budget.

    What Services do Window Installers Offer?

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

    Full-frame installations involve replacing the full window, including the sill, frame and trim. You most likely need a full-frame installation when you want a new style or your window has noticeable rot or deterioration. Because these installations are more involved, they will raise the overall cost. Pocket installations are on the simpler end and won’t cost as much, as they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

    Your window replacement company will be able to help you figure out what’s best for your needs. In Cromwell, the decision will mostly depend on the age of your windows and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional examine your frames and window sills.

    How We Choose the Best Window Installers in Cromwell

    EcoWatch is different from other reviewers because we examine these companies through a sustainability lens. We have decided to assess the best window replacement companies in Cromwell mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. 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 pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.

    Work Quality

    We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer included in our guide to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.

    Customer Reviews

    Customer feedback is another very important review factor. If most customers don’t have positive things to say about their service from a certain window installation company, it won’t be featured on EcoWatch.

    Cost

    This one is a give-and-take: as with other services, cheap window companies are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.

    Warranty

    As discussed previously, windows are a hefty investment, so you’ll want to make sure that investment is protected. Window installation companies that have 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 a proven track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

    Cromwell, CT Window Replacement FAQs

    How much does a window install cost?

    The national average cost to replace a window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

    What kind of window is the most energy-efficient?

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

    When should I use a window installation company?

    Unless you have experience with home improvement projects and have the time to replace your own windows, we recommend hiring the pros. The process of installing windows is complicated and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.

    When is the best time of year to replace windows?

    Though you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, the weather should be dry, as rain can make the installation more difficult.

    Should I replace my windows all at the same time?

    If your windows are greater than 20 years old, it’s probably time to replace all of them. By that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
