How Installing Energy-Efficient Windows in Libertyville Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to make the switch:

• Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that amount, which helps you save some money on your bills.
• 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 harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if you have an older home.
• Decrease your carbon footprint: In Libertyville, you can lower your indirect greenhouse gas emissions by about 449 pounds per year once you upgrade to energy-efficient windows.

Estimated Cost of Window Replacement in Libertyville

When researching window installation, each company offers different services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

Though the typical cost of replacing a single window is around $600, it can range from $200 to $1,200. But costs will vary considerably based on the current condition of your home, the quality of your products, the number of windows you need and your location. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.

It’s also worth keeping in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that upgrading the windows on your Libertyville home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Requesting free quotes from several companies is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the complete window, including the sill, trim and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot. Because these installations are more involved, they will increase the total cost. A pocket installation involves replacing a window without taking out the entire frame, which is generally 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 assist you. Generally, the decision is influenced by factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Libertyville

EcoWatch reviews differ from other reviews since we look at these companies through a sustainability lens. We have decided to evaluate the best window replacement companies in Libertyville mainly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce your electricity 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 a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive things to say about their service from 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 companies won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a spectrum 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 give you 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 been in the industry for a while. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
