    How Installing Energy-Efficient Windows in Derry Saves You Money

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

    • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
    • Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can lower your carbon footprint by about 12%, according to Energy Star.
    • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
    • Save money on electricity bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll use less energy to heat or cool your home.

    Estimated Cost of Window Replacement in Derry

    Each window replacement company offers various services and has varying prices based on a few factors.

    How Much Do New Windows Cost?

    Though the average cost to replace one window is around $600, it can range from $200 to $1,200. Costs will differ significantly based on the current condition of your home, your location, the quality of your products and the number of windows you need. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase overall project costs.

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

    Asking for free quotes from multiple companies is the best way to find out which one is right for you.

    What Services do Window Installers Offer?

    In general, there are two types of window replacement services you can get: full-frame and pocket installations.

    A full-frame installation is a replacement of the full window. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves other materials, such as insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won’t cost as much, as they involve simply replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.

    If you’re still debating which kind of installation you need, you can consult with your installer and get their advice. The decision mostly depends on how old the frames are and if there’s any damage present.

    How We Choose the Best Window Installers in Derry

    In our search to make your home improvements easier and more eco-friendly in Derry, the EcoWatch team chose the above companies as the best window installation companies in the city. We’ve evaluated the top window replacement companies in Derry mainly based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

    Service Area

    Because this is a guide for Derry, we only included companies that cover the city. There are certainly reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Derry.

    Work Quality

    When selecting new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand 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

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

    Cost

    This one is a give-and-take: similar to most services, cheap window installation companies won’t always provide the most quality service. Still, 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 to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

    Last but not least, we like to see companies that have a good track record in the industry. 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.
