Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home’s energy efficiency can also have a considerable impact on home energy conservation. If your windows are made of traditional materials, or are outdated or damaged, you could be sending 25-30% of your home’s heat or cool air out of them.
Installing efficient windows on your home can help you save money every month on your electricity bills — and you can help the environment, too.
Efficient windows are of particular importance in New Berlin, where winters are long and cold. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $483 a year.

How Installing Energy-Efficient Windows in New Berlin Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways switching out your windows could benefit you:
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by 497 pounds per year on average.
- Save money on electricity bills: After you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll require less energy to heat or cool your house.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
Estimated Cost of Window Replacement in New Berlin
Each window installation company offers varying services and has varying prices based on a few factors.
How Much Do New Windows Cost?
According to our market research, the typical cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. This is because of the fact that the cost of window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.
It’s important to keep in mind that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save New Berlin homeowners $483+ a year when replacing single-pane windows.
Costs will also vary based on the material you choose for your window frames. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
Generally, there are two types of window installation services companies offer: full-frame and pocket installations.
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant deterioration. Full-frame installations require more time and labor and will increase overall costs. A pocket installation involves replacing a window without taking out the whole frame, which is usually less expensive than a full-frame installation.
Your window replacement company should be able to help you decide what’s best for your needs. In New Berlin, the decision will mostly depend on how old your home is and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in New Berlin
In our search to find the most reliable, eco-friendly window installers in New Berlin, the EcoWatch Reviews team examined dozens of companies before settling on these. Along with energy efficiency, we analyzed several window installers in New Berlin and ranked them using the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve New Berlin so you can find the right window installation company near you.
Work Quality
We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each installer featured on this list to ensure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good things to say about their experience with a certain installer, you won’t see it featured on EcoWatch.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of New Berlin’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of New Berlin window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
New Berlin, WI Window Replacement FAQs
What is the average cost to install windows in a home?
The national average cost of installing a window is around $600 but can range between $200 and $1,200, based on a variety of factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which type of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
When do I have to use a window installation company?
Unless you have home repair skills and have all the necessary tools to replace your own windows, we recommend hiring a professional. The window installation process is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and safer alternative.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, you probably need to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
How long does it usually take to install windows?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed in a typical 8-hour work day.
