    How Installing Energy-Efficient Windows in Winchester Saves You Money

    When you switch to energy-efficient windows, you may see several perks, including:

    • Reduce your carbon footprint: In Winchester, you can lower your indirect greenhouse gas emissions by about 147 pounds per year once you install energy-efficient windows.
    • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
    • Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that amount, which helps you save some money on your bills.
    • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its real estate value.

    Estimated Cost of Window Replacement in Winchester

    Windows come in various shapes and sizes, so costs and services will differ considerably. Here are the typical costs and the primary services that you’ll find from window installers.

    How Much Do New Windows Cost?

    The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. But prices vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations and replacements, which will add extra costs to your project.

    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. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.

    Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

    What Services do Window Installers Offer?

    In regard to window replacements, there are typically two types that your provider will offer: full-frame and pocket installations.

    Full-frame installations involve replacing the total window, including the frame, sill and trim. Full-frame installations are necessary when you want a new style or your window has noticeable deterioration. Because these installations are more involved, they will raise the total cost. A pocket installation entails replacing a window within the frame that’s already there. This means instead of tearing out the whole unit and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

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

    How We Choose the Best Window Installers in Winchester

    In our hunt to find the most reliable, eco-friendly window installers in Winchester, the EcoWatch team examined dozens of companies before settling on these. We’ve assessed the top window installers in Winchester mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your energy 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 installers that serve the Winchester area so you can find the best window installation company near you.

    Work Quality

    When it comes to new windows, the quality and range 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

    Customer feedback is another very important review factor. If the majority of customers don’t have nice things to say about their service from a certain installer, it won’t be featured on EcoWatch.

    Cost

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

    Warranty

    As discussed, windows are a sizable investment, so you’ll want to make sure that investment is protected. Window installation companies that have 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 experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

    Winchester, CT Window Replacement FAQs

    How much should window installation cost?

    The national average cost of replacing one window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is generally dependent on the type and material of the window, the location of your property and the size 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 various types of windows you can get for your house, such as bay windows, casement windows, double-hung and single-hung windows, picture windows, awning windows, slider windows and transom windows.

    Can I replace my own windows?

    While it is possible to install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help ensure that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

    What time of year should I replace my windows?

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

    Should I replace my windows all at the same time?

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