20 Best Window Companies in Forest Park, IL (2025 Reviews)

How Installing Energy-Efficient Windows in Forest Park Saves You Money

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

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

Estimated Cost of Window Replacement in Forest Park

Each window replacement company offers varying services and has varying price points depending on a few factors.

How Much Do New Windows Cost?

On average, Forest Park homeowners can expect their window installations to range from $250 to $1,200. The average cost sits at about $600. How much it will cost varies depending on several factors, including size, type, material, the location of your home, number of windows and more.

It’s also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that switching out the windows on your Forest Park home can mean 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 installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Requesting free quotes from several installers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

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

A full-frame installation replaces the total window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time, it will be more expensive than a pocket installation. A pocket installation entails replacing a window within the old frame. This means instead of tearing out the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to advise you on the best type for your project. In Forest Park, the choice will mostly be influenced by how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Forest Park

The EcoWatch Reviews team is different from other reviewers because we examine these companies through a sustainability lens. We have evaluated the top window installation companies in Forest Park mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Forest Park, we only included companies that serve the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Forest Park.

Work Quality

When choosing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do rate window installers higher 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 good feedback about their experience with a certain installer, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that offer 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 installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
