      How Installing Energy-Efficient Windows in Grayslake Saves You Money

      Energy-efficient windows can offer benefits in several ways. Here are a few reasons you may want to make the switch:

      • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
      • Reduce your carbon footprint: In Grayslake, you can cut your indirect greenhouse gas emissions by about 449 pounds per year once you upgrade to energy-efficient windows.
      • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.
      • Save money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you need less energy.

      Estimated Cost of Window Replacement in Grayslake

      Each window installation company provides various services and has varying costs based on a few factors.

      How Much Do New Windows Cost?

      Though the national average cost of replacing a single window is around $600, it can range anywhere from $200 to $1,200. This is because window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.

      It’s important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Grayslake homeowners $298+ a year when replacing single-pane windows.

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

      What Services do Window Installers Offer?

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

      Full-frame installations are necessary when you want a new style or your window has significant rot. With this service, your installers will replace the whole window, including the trim, frame and sill. Pocket installations are simpler and won’t carry as large a bill, as they involve simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.

      If you’re still debating which type of installation to get, you can ask your provider and get their recommendation. The choice mostly depends on the age of your window frames and if there’s any damage present.

      How We Choose the Best Window Installers in Grayslake

      EcoWatch reviews differ from most reviews since we’re examining these companies through a sustainability lens. We have reviewed the top window installation companies in Grayslake mostly 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 takes the following factors into consideration:

      Service Area

      This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Grayslake so you can find a quality window installation company near you.

      Work Quality

      When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

      Customer Reviews

      Customer feedback is another super important review factor. If most customers don’t have nice things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.

      Cost

      This one is a give-and-take: similar to other services, cheap window installation companies won’t always provide the highest quality service. Still, 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

      As discussed previously, windows are a serious investment, so you’ll want to be certain 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 Grayslake’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Grayslake window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

      Grayslake, IL Window Replacement FAQs

      How much should window installation cost?

      The typical cost of installing a single window can range between $450 and $650. There are a variety of factors that affect how much it costs, such as the materials used in designing the windows, your property’s location, how energy-efficient the windows are, the number of windows, styles and sizes of windows and local labor costs.

      What type of window is the best for energy efficiency?

      A window’s energy efficiency depends on 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 and are certified by the U.S. Department of Energy.

      When do I need to use a window installation company?

      You should hire a window installation professional whenever you want to upgrade your windows. Installing windows is a complex process that can be difficult to do on your own, so it’s best handled by the professionals.

      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, they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.

      How long does it usually take to install windows?

      Because the average installation time of a window is 30 minutes, around 16 windows can be installed in an 8-hour work day.
