    How Installing Energy-Efficient Windows in Brunswick Saves You Money

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

    • 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 fading of your furniture, carpet and other valuables.
    • Protect your investment: When you have an older home, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
    • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Brunswick, that’s about 163 pounds per year on average.
    • Save on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.

    Estimated Cost of Window Replacement in Brunswick

    When considering window installation, each company offers different services and prices. Let’s take a look at some typical costs and services.

    How Much Do New Windows Cost?

    On average, homeowners in Brunswick can anticipate that most window installations will range from $250 to $1,200, with the average cost sitting at about $600. This is due to the fact that the cost of window installations depend 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.

    Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

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

    What Services do Window Installers Offer?

    The first step of an installation is to clarify whether you want a full-frame or pocket installation.

    Full-frame installations involve replacing the complete window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has significant damage or rot. These installations are more involved and will raise the total cost. A pocket installation entails replacing a window without taking out the complete frame, which is usually less expensive than a full-frame installation.

    Your window installation company should be able to help you understand what’s best for your needs. In Brunswick, the decision will mostly depend on how old your home is and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional assess your frames and window sills.

    How We Choose the Best Window Installers in Brunswick

    In our hunt to make your home improvements easier and more eco-friendly in Brunswick, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed window companies all across the state and ranked them using the following methodology:

    Service Area

    This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.

    Work Quality

    When installing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

    Customer Reviews

    Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive feedback about their experience with a certain company, 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 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 to many homeowners. For that reason, 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 earn higher rankings by our standards. We like to see at least ten years of experience.

    Brunswick, ME Window Replacement FAQs

    What is the typical cost to install new windows in a home?

    The national average cost to install a window is about $600 but can range from $200 to $1,200, based on several factors. The price is often dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

    What are the kinds of windows?

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

    Do I really have to use a window installation company?

    You should use a window installation professional whenever you need new windows. Installing windows is a complex process that can take a lot of time, so it’s best left to the professionals.

    Should I replace my windows all at once?

    If your windows are greater than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
