Why you can trust EcoWatch

The Department of Energy estimates that heat or cool air lost through traditional or outdated windows could account for around 30% of residential energy climate use. In Greendale, where the energy bills are an average of $54 per month, that's almost $$195 per year wasted.
Replacement windows improve your home's insulation, not only making you and your family more comfortable during the summer and winter, but also saving you some money and helping the environment.
Because windows are so important for your home, choosing the best company for you is a big decision to make. That's why the EcoWatch team has curated this list of the best window replacement companies, so you can more easily make an informed decision.

Window Install & Replacement
Calculate how much you can expect to pay for window installation and replacement in Greendale, 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 Greendale Saves You Money
Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to take the plunge and make the switch:
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
- More efficient energy usage in your home: Because the winters can get cold in Greendale, homeowners usually rely on their heater a lot. Energy-efficient windows decrease how much heat is lost through your windows, which makes it easier to keep your house warm.
- Save on power bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save around $426 annually on your energy bills in Greendale.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Greendale
Windows come in varying shapes, purposes and styles, so costs and services will differ considerably depending on your project. Below, we describe the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
Generally, Greendale homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. But prices differ considerably 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 provide door installations and replacements, which carry a higher price tag.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — particularly during the winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Greendale homeowners $426+ a year after replacing single-pane windows.
We advise requesting free quotes from multiple window companies to find the one that works best for you.
What Services do Window Installers Offer?
In regard to window installations, there are generally two kinds that your provider will have: full-frame and pocket installations.
A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. A pocket installation involves replacing a window within the existing frame. This means instead of taking out the whole window and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installer can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Greendale
EcoWatch differs from most reviewers since we're examining these companies through a sustainability lens. We have evaluated the best window installers in Greendale mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Greendale so you can find the best 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 in our guide to ensure its contractors are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, warranty, quality of parts, professionalism, quality of installation and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a significant investment, so you'll want to be certain that investment is well protected. Window installation companies that provide 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 years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
