Why you can trust EcoWatch
Whether you're updating for aesthetics or have damaged windows, windows play a crucial role in conserving your home's electricity. Poor windows can decrease your home's energy efficiency by up to 30%, according to the Department of Energy. In Muskego, that's nearly $483 a year that you could save on your power bills after making the switch.
That's also bad for the environment because the extra energy used by old windows increases your carbon footprint.

Calculate how much you can expect to pay for window installation and replacement in Muskego, WI using our customized window cost calculator.

How Installing Energy-Efficient Windows in Muskego Saves You Money
When you switch to energy-efficient windows, you may see some benefits, including:
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- Save money on electricity bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll use less energy to heat or cool your home.
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- More efficient energy usage in your home: Because the winters can get cold in Muskego, homeowners usually rely on their heater a lot. Energy-efficient windows lower how much heat is lost through your windows, making it easier to keep your home warm.
Estimated Cost of Window Replacement in Muskego
Each window installation company offers various services and has varying price points based on a few factors.
How Much Do New Windows Cost?
Even though the average to install a single window is around $600, it can range from $200 to $1,200. But prices differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which have a higher price tag.
Whether or not you want to install energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $483 a year on your energy bills in Muskego.
The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the entire window, including the trim, frame and sill. A pocket installation involves replacing a window without replacing the frame. This means instead of tearing out the whole window and reinstalling it, the window installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're not sure which window installation service you should get, your installer can assist you. In general, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Muskego
In our hunt to make your home improvements easier and more eco-friendly in Muskego, EcoWatch examined many companies before deciding on these. We have assessed the top window installers in Muskego mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Muskego so you can find the right window installation company near you.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns 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
Cheaper windows certainly don't 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 scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. 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.
Muskego, WI Window Replacement FAQs
What is the typical cost to replace windows in a home?
The typical cost of replacing a window ranges from $450 to $650. There are several factors that affect the price, such as the materials used in designing the windows, how energy-efficient the windows are, the number of windows, styles and sizes of windows, local labor costs and your property's location.
Which type of window should I get?
A window's energy efficiency is influenced by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
Do you really need to use a window installation company?
Unless you're handy and have all the tools you need to replace your own windows, we recommend hiring a professional installer. 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 save some money by doing it yourself, hiring a company is a faster, more efficient and safer alternative.
Should I replace my windows all at once?
If you're upgrading your windows because of energy-efficiency, replacing all of the windows together is the only way to gain that benefit. However, if you have just a few windows that are damaged or leaky, you can replace just those.
