Calculate how much you can expect to pay for window installation and replacement in Oshkosh, WI 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 Oshkosh Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to consider making the switch:
- Better temperature control in your home: When you live in a city like Oshkosh where the winters can get cold, you usually have to rely on your heater to keep your home warm. Energy-efficient windows can cut back on how hard your heater needs to work to heat your home.
- Better temperature control in your home: Living in a warm place like Oshkosh usually means needing your AC to keep your house cool. Energy-efficient windows can cut back on how hard your AC needs to work to cool your home.
- Save money on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of residential energy use. Switching to energy-efficient windows can help lower that number, which helps you save $522 a year on your bills.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if you have an older home.
Estimated Cost of Window Replacement in Oshkosh
Each window installation company offers various services and has different costs based on a few factors.
How Much Do New Windows Cost?
Although the average to install one window is about $600, it can range from $200 to $1,200. These numbers vary based on the specifics of your installation, such as type, size, material, the location of your home, number of windows and more.
It's important to keep in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Oshkosh homeowners $522+ a year when replacing single-pane windows.
Asking for free quotes from multiple providers is the best way to figure out which one will work best for your budget.
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 entail replacing the complete window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable rot or deterioration. Because full-frame installations are more involved, they will raise the total cost. A pocket installation involves replacing a window within the existing frame. So, instead of taking out the whole unit and rebuilding it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company will be able to help you understand what's best for your needs. In Oshkosh, the decision will mostly depend on the age of your home and if there's any moisture damage. Wood can decay if it's not properly maintained over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Oshkosh
EcoWatch is different from other reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in Oshkosh and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve the Oshkosh area so you can find the right window installation company near you.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each company included on this list to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have nice feedback 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 most services, cheap window installers won't always provide the most quality service. On the other hand, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Oshkosh's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Oshkosh window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Oshkosh, WI Window Replacement FAQs
What is the average cost to replace windows?
The average cost of replacing a single window can range between $450 and $650. There are several factors that affect how much it costs, including the number of windows, styles and sizes of windows, how energy-efficient the windows are, local labor costs, your property's location and the materials used in designing the windows.
What are the kinds of windows?
There are several different types of windows you can get for your home, such as transom windows, double-hung and single-hung windows, picture windows, casement windows, awning windows, slider windows and bay windows.
What do window installation companies do?
Window installation professionals will do the entire process — from replacing old windows with brand new ones to cleaning up afterward. In addition, some companies offer window manufacturing, customization and repairs.
How long does it usually take to install windows?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you have a lot of windows that need to be installed.
What time of year is a good time to replace my windows?
Even though you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, it shouldn't be raining, because rain can make the installation harder.
