Calculate how much you can expect to pay for window installation and replacement in Portage, 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 Portage Saves You Money
By upgrading to energy-efficient windows, you can benefit in several ways, such as:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- 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.
- Better temperature control in your home: Living in a warm place like Portage usually means relying on your air conditioner to keep your home cool. Energy-efficient windows can reduce how hard your AC needs to work to cool your home.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help lower that amount, which helps you save some money on your bills.
Estimated Cost of Window Replacement in Portage
Each window installer provides varying services and has different costs depending on several factors.
How Much Do New Windows Cost?
According to our market research, the average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. But prices vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations and replacements, which will add extra costs to your project.
Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
Something else that influences the overall cost is the material you select for your frame. Aluminum frames are typically the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as 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?
When considering window installations, in general there are two kinds that your provider will offer: full-frame and pocket installations.
A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. As this type of installation requires more time, it will be more expensive than a pocket installation. Pocket installations are simpler and won't cost as much, as 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.
If you're still trying to decide which kind of installation to get, you can ask your installer and get their advice. The choice mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Portage
In our hunt to find the most reliable, eco-friendly window installers in Portage, the EcoWatch team chose the above companies as the best window installation companies in the city. We have evaluated the top window installers in Portage mostly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
When installing 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
Customer feedback is another very important review factor. If the majority of customers don't have positive feedback about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a substantial investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Portage's climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of Portage window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Portage, WI Window Replacement FAQs
What is the average cost to install windows in a home?
The national average cost to install one window is around $600 but can range from $200 to $1,200, depending on several factors. The price is usually dependent on the size of the window, the location of your property and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which kind of window should I get?
A window's energy efficiency is affected by a variety of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
Can you replace your own windows?
If you're handy and have the time and patience to do the job right, you may be able to install your own windows. However, if you don't have the time or skills, we recommend hiring a professional.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, it's most likely time to replace all of them. By that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
