    How Installing Energy-Efficient Windows in Exeter Saves You Money

    When you upgrade to energy-efficient windows, you may see a few perks, including:

    • Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 152 pounds per year on average.
    • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
    • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
    • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.

    Estimated Cost of Window Replacement in Exeter

    Windows come in different shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and services that you’ll find from the average window installation company.

    How Much Do New Windows Cost?

    Typically, Exeter homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at around $600. This is because of the fact that window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.

    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 per year when you install single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your 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, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

    What Services do Window Installers Offer?

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

    Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot or deterioration. With this service, your professionals will replace the complete window, including the trim, sill and frame. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.

    Your window installation company will be able to advise you on the best type for your project. In Exeter, the choice will mostly be influenced by the efficiency of your home and the age of your existing frames.

    How We Choose the Best Window Installers in Exeter

    In our hunt to make your home improvements easier and more eco-friendly in Exeter, EcoWatch chose the above companies as the best window installation companies in the city. We have decided to review the best window installation companies in Exeter mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

    Service Area

    Since this is a guide for Exeter, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Exeter.

    Work Quality

    When picking new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

    Customer Reviews

    Customer feedback is another very important review factor. If the majority of customers don’t have nice feedback about their experience with a certain installer, you won’t see it featured on EcoWatch.

    Cost

    Cheaper windows don’t necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

    Warranty

    As discussed, windows are a considerable investment, so you’ll want to make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

    Years of Experience

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

    Exeter, NH Window Replacement FAQs

    What is the average cost to replace windows in a home?

    The typical cost of installing one window ranges from $450 to $650. There are several factors that affect the price, including local labor costs, styles and sizes of windows, the number of windows, the materials used in designing the windows, how energy-efficient the windows are and your property’s location.

    What kind of window is the best for energy efficiency?

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

    What do window installers do?

    Window installation professionals will do the entire process — from replacing old windows with brand-new ones to cleaning up afterward. In addition, many companies offer window manufacturing, customization and repairs.

    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 probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.

    Should I replace my windows all at once?

    If you’re upgrading your windows to save on your energy bills, replacing all the windows at the same time is the only way to gain that benefit. On the other hand, if you have just one or two windows that are broken or leaky, you can replace just those.
