    How Installing Energy-Efficient Windows in Mastic Beach Saves You Money

    There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:

    • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Mastic Beach, that’s about 307 pounds per year on average.
    • Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its value.
    • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
    • Save money on power bills: Installing energy-efficient windows reduces your energy bills by about 12% since you need less energy.

    Estimated Cost of Window Replacement in Mastic Beach

    Let’s go over the cost of window replacement and the types of services you may need for your home.

    How Much Do New Windows Cost?

    The national average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. How much it will cost varies depending on several factors, including material, type, size, number of windows, the location of your home and more.

    Bear in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

    The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are solid 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?

    There are typically two types of window installation services: full-frame and pocket installations.

    A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve other materials, like insulation and drip edges, which increase the total cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won’t carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you should opt for a full-frame installation instead.

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

    How We Choose the Best Window Installers in Mastic Beach

    In our hunt to find the most reliable, eco-friendly window installers in Mastic Beach, EcoWatch landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on 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 often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

    Customer Reviews

    We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across most other categories, including professionalism, quality of installation, cost, warranty, quality of parts and more.

    Cost

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

    Warranty

    Protecting your investment in new windows is important. That’s why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

    Years of Experience

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