How Installing Energy-Efficient Windows in Waukesha Saves You Money
When you upgrade to energy-efficient windows, you may see several benefits, such as:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
- Save money on power bills: Because energy-efficient windows reduce the amount of energy needed to heat or cool your home, they can help you save about $483 annually on your energy bills in Waukesha.
- Decrease your carbon footprint: By using less energy after you upgrade to Energy Star certified windows, you’ll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
Estimated Cost of Window Replacement in Waukesha
Windows come in different purposes, shapes and styles, so costs and services will vary tremendously based on several factors. Below, we go over the average cost and services that you’ll find from window replacement companies.
How Much Do New Windows Cost?
According to our market research, the typical cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 for each window. How much it will cost varies depending on several factors, including type, size, number of windows, the location of your home, material and more.
With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially during the winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Waukesha homeowners $483+ per year after replacing single-pane windows.
Getting free quotes from multiple companies is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first question to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations entail replacing the total window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has significant damage. Because these installations are more involved, they will increase the total cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are simpler and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.
If you’re still trying to decide which kind of installation you need, you can talk to your provider and get their advice. The choice mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in Waukesha
EcoWatch reviews differ from other reviews since we examine these companies through a sustainability lens. We have decided to assess the best window installers in Waukesha mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower 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 Waukesha, we paid more attention to companies that serve the city. There are certainly reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Waukesha.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the type 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
We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, quality of parts, quality of installation, warranty, cost and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers may not provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a sizable investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Waukesha, WI Window Replacement FAQs
How much does window installation cost?
The average cost of replacing a window ranges from $450 to $650. There are many factors that affect how much it costs, which include the materials used in designing the windows, your property’s location, local labor costs, styles and sizes of windows, how energy-efficient the windows are and the number of windows.
What kind of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you’ll get the most energy-efficient windows, look for models with the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.
What do window installation companies do?
Window installers travel to your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation.
How do you know it’s time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
