Why you can trust EcoWatch
A guide on the top window replacement companies in Germantown may not seem like the most captivating article on the EcoWatch site, but trust us, windows have a more direct impact on your life than you might think. If you have traditional, outdated windows, your HVAC system could be working extra hard to heat or cool your home. This means higher power bills.
Replacement windows improve the insulation in your home, not only making you and your family more comfortable during the summer and winter, but also saving you some money and helping the environment.
Efficient windows are especially important in Germantown, where winters are long and cold. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $489 a year.

How Installing Energy-Efficient Windows in Germantown Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to take the plunge and make the switch:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- 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.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that amount, which helps you save more on your bills.
- Reduce your carbon footprint: In Germantown, you can reduce your indirect greenhouse gas emissions by about 497 pounds per year when you install energy-efficient windows.
Estimated Cost of Window Replacement in Germantown
Let's take a look at the cost of updating your windows and the types of services you may need for your home.
How Much Do New Windows Cost?
According to our research, the average cost of replacing a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. Costs will differ significantly based on your location, the number of windows you need, the current condition of your home and the quality of your products. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase your overall project costs.
With windows, efficiency is one of the most important factors for most homeowners. Efficient windows may cost more upfront, but by increasing the efficiency of your home — particularly during the winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Germantown homeowners $489+ each year after replacing single-pane windows.
Asking for free quotes from multiple companies is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won't cost as much, as they entail merely 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 replacement company will be able to help you understand what's best for your needs. In Germantown, the decision will mostly be based on how old your home is and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Germantown
EcoWatch is different from most reviewers, as we're examining these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Because this is a guide for Germantown, we gave more points to companies that serve the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Germantown.
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 brand 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 very important review factor is customer feedback. If the majority of customers don't have positive feedback about their service from a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window companies may not provide the most quality service. Still, we want to ensure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial investment, so you'll want to make sure that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor 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 installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Germantown, WI Window Replacement FAQs
How much should a window install cost?
The national average cost of replacing a window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is often influenced by the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What type of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
What do window installers do?
Window installation companies cover the entire process — from replacing old windows with brand new ones to cleaning up afterward. Additionally, many companies offer window manufacturing, customization and repairs.
How long does it typically take to install windows?
Each window takes around 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is typically better for installing replacement windows. Additionally, the weather should be dry, since rain can make the installation harder.
