How Installing Energy-Efficient Windows in Mercer Saves You Money

There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:

  • Decrease your carbon footprint: By using less energy after upgrading to energy-efficient windows, you'll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
  • Save on electricity bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll require less energy to heat or cool your home.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Mercer

Windows come in various purposes, shapes and styles, so costs and services will differ considerably depending on your project. Below, we go over the typical cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range from $200 to $1,200. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which will add extra costs to your project.

With windows, efficiency is the most important factor for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Mercer homeowners $323+ per year after replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from 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 provide decent insulation for your home.

What Services do Window Installers Offer?

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

A full-frame installation replaces the total window, including the sill, frame, trim and the window panes. Because this type of installation is more involved, it will cost more than a pocket installation. A pocket installation means replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

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

How We Choose the Best Window Installers in Mercer

The EcoWatch Reviews team differs from most reviewers, as we look at these companies through a sustainability lens. We have reviewed the best window installation companies in Mercer mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality 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 on this list to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If most customers don't have nice feedback about their service from a certain window installation company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: as with other services, cheap window companies won't always provide the highest 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

As discussed previously, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Mercer, IL Window Replacement FAQs

How much should a window install cost?

The national average cost to replace one window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is generally dependent on the size of the window, the location of your property and the type and material 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.

Which kind of window is the best?

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 since they are certified by the U.S. Department of Energy.

Can I replace my own windows?

If you're handy and have the time and patience to do the job right, you may be able to install your own windows. However, if you don't have the time or know-how, we recommend hiring a professional.

How do you know it's time to replace your 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 any damage on them, or they have become difficult to open or close, they may need to be replaced.

Should I replace all my windows at once?

If you want to get more efficient windows and save money on energy costs, replacing all the windows together is the only way to see a noticeable difference. However, if you have just a few windows that are broken or leaky, you can replace just those.
