    How Installing Energy-Efficient Windows in Derby Saves You Money

    There are several perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

    • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
    • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out damaging UV rays.
    • Reduce your carbon footprint: By using less energy once upgrading to energy-efficient windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
    • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease that amount, therefore saving you about 12% more on your bills.

    Estimated Cost of Window Replacement in Derby

    Windows come in varying purposes, styles and shapes, so costs and services will differ tremendously depending on several factors. Below, we detail the typical cost and services that you can get from window installation companies.

    How Much Do New Windows Cost?

    On average, Derby homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at approximately $600. Costs will differ considerably depending on the quality of your products, the number of windows you need, the current condition of your home and your location. Many window companies also offer replacement door installations and other add-ons like coating, baths, shutters and more. These extra services will increase your overall project costs.

    It’s important to keep in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Derby homeowners $420+ a year when replacing single-pane windows.

    We advise getting free quotes from multiple window companies to find the one that works best for your budget.

    What Services do Window Installers Offer?

    The first step of an installation is to think about whether you need a full-frame or pocket installation.

    Full-frame installations entail replacing the total window, including the frame, trim and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable damage or rot. These installations are more involved and will increase the total cost. A pocket installation entails replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

    If you’re not sure which kind of window installation service you need, your installer should be able to advise you. Generally, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

    How We Choose the Best Window Installers in Derby

    In our hunt to make your home improvements easier and more eco-friendly in Derby, the EcoWatch team evaluated dozens of companies before landing on these. We have reviewed the top window installation companies in Derby mostly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

    Service Area

    This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Derby area so you can find the best window installation company near you.

    Work Quality

    We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer featured in our guide to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

    Customer Reviews

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

    Cost

    This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to ensure 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. For that reason, window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

    Years of Experience

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

    Derby, CT Window Replacement FAQs

    How much should window installation cost?

    The average cost to replace a window can range from $450 to $650. There are a variety of factors that affect the price, including local labor costs, the materials used in designing the windows, styles and sizes of windows, your property’s location, the number of windows and how energy-efficient the windows are.

    What are the kinds of windows?

    The most common types of windows for homes are double-hung and single-hung windows, casement windows, awning windows, slider windows, picture windows, transom windows and bay windows.

    Can you replace your own windows?

    If you’re handy and know how to replace a window, you may be able to install your own windows. However, if you don’t have the time or experience, we recommend hiring a professional.

    When is it time to replace your windows?

    Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
