20 Best Window Companies in Frankfort, IL (2025 Reviews)

How Installing Energy-Efficient Windows in Frankfort Saves You Money

By switching to energy-efficient windows, you can enjoy several benefits, including:

• 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 fading of your furniture, carpet and other valuables.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
• Save money on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of household energy use. Switching to energy-efficient windows can help lower that amount, which helps you save more on your bills.
• Decrease your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Frankfort

When considering window installation, each company offers varying services and costs. Let’s go over some average costs and services.

How Much Do New Windows Cost?

Though the typical cost of replacing one window is about $600, it can range anywhere from $200 to $1,200. Costs will differ considerably depending on the current condition of your home, your location, the quality of your products and the number of windows you need. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase overall project costs.

Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $307 a year on your energy bills in Frankfort.

Something else that influences the overall cost is the material you select for your frame. Aluminum frames are typically the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

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

A full-frame installation is a total window replacement. This service involves taking out the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, like insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves replacing a window without taking out the complete frame, which is generally less expensive than a full-frame installation.

If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Frankfort, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Frankfort

EcoWatch reviews differ from most reviews because we examine these companies through a sustainability lens. We have decided to assess the best window replacement companies in Frankfort mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. 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

Since this is a guide for Frankfort, we paid more attention to companies that serve the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Frankfort.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company in our guide 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

We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including cost, quality of parts, professionalism, quality of installation, warranty and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Because of Frankfort’s climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of Frankfort window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
