    How Installing Energy-Efficient Windows in Cary Saves You Money

    Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways switching out your windows could help you:

    • Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
    • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Cary, that’s about 449 pounds per year on average.
    • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
    • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.

    Estimated Cost of Window Replacement in Cary

    Windows come in varying styles, purposes and shapes, so costs and services will vary tremendously depending on several factors. Below, we detail the average cost and services that you’ll find from window installation companies.

    How Much Do New Windows Cost?

    The national average cost to install one window is about $600 but can range from $200 to $1,200. Costs will differ considerably depending on the number of windows you need, the quality of your products, your location and the current condition of your home. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.

    It’s also worth noting that energy-efficient windows will cost more initially, but Energy Star estimates that switching out the windows on your Cary home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

    We recommend requesting free quotes from multiple window installation companies to find the right windows and the company that works best for you.

    What Services do Window Installers Offer?

    There are generally two kinds of window replacement services: full-frame and pocket installations.

    A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window within the frame that’s already there. So, instead of taking out the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

    Your window installer can help you choose which type of installation you should get.

    How We Choose the Best Window Installers in Cary

    The EcoWatch Reviews team differs from most reviewers since we’re examining these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Cary and assigned rankings using the following methodology:

    Service Area

    Since this is a guide for Cary, we only included companies that serve the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Cary.

    Work Quality

    We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company on this list to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

    Customer Reviews

    Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive feedback about their service from a certain company, you won’t see it featured on EcoWatch.

    Cost

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

    Warranty

    As discussed previously, windows are a hefty investment, so you’ll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

    Years of Experience

    Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

    Cary, IL Window Replacement FAQs

    How much should window installation cost?

    The national average cost to install one window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically influenced by 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 initially but can save you a decent amount of money a year in energy bills.

    What are the different types of windows?

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

    Can I install my own windows?

    Although it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Using a window replacement company can help ensure that the job is done properly and that you won’t have to spend the time and effort to do it yourself.

    When is the best time of year to replace windows?

    Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your home, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.

    How long does it typically take to install windows?

    Each window takes around 30 minutes to install based on the type of window. However, the window installation can take two days or more if you have a lot of windows that need to be installed.
