Calculate how much you can expect to pay for window installation and replacement in Freeburg, IL using our customized window cost calculator.
Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.
How Installing Energy-Efficient Windows in Freeburg Saves You Money
When you upgrade to energy-efficient windows, you may see some perks, including:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
- More efficient energy use in your household: Because the winters can get very cold in Freeburg, homeowners often depend on their heater during that time. Energy-efficient windows reduce the amount of heat that is lost through your windows, which makes it easier to keep your house warm.
- Save money on power bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll use less energy to heat or cool your home.
Estimated Cost of Window Replacement in Freeburg
Let's take a look at the cost of replacing your windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
Even though the average of replacing a single window is around $600, it can range anywhere from $200 to $1,200. How much it will cost varies depending on several factors, including the location of your home, material, number of windows, size, type and more.
It's important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Freeburg homeowners $316+ a year when replacing single-pane windows.
We advise getting free quotes from several window installers to find the one that works best for you.
What Services do Window Installers Offer?
The first thing to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations are on the simpler end and won't carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.
Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Freeburg
In our hunt to make your home improvements easier and more eco-friendly in Freeburg, the EcoWatch Reviews team assessed dozens of companies before settling on these. Along with energy efficiency, we reviewed several window installers in Freeburg and ranked them using the following methodology:
Service Area
Because this is a guide for Freeburg, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Freeburg.
Work Quality
When choosing new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive things to say about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you'll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Freeburg's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Freeburg window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Freeburg, IL Window Replacement FAQs
What is the typical cost to install new windows in a home?
The typical cost to replace a window ranges between $450 and $650. There are several factors that affect how much it costs, which include how energy-efficient the windows are, local labor costs, your property's location, the number of windows, styles and sizes of windows and the materials used in designing the windows.
What are the most common kinds of replacement windows?
The most common types of windows for homes include: awning windows, picture windows, bay windows, slider windows, casement windows, double-hung and single-hung windows and transom windows.
Can you replace your own windows?
If you're handy and have experience with similar home improvement projects, you may be able to install your own windows. But if you don't have the time or experience, we recommend hiring a professional.
How often do you need to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
