How Installing Energy-Efficient Windows in Milan Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to take the plunge and make the switch:
- More efficient energy use in your home: In Milan where the winters can be very cold, energy-efficient windows lower how much heat is lost through your windows, making it easier to keep your house warm.
- 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.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Reduce your carbon footprint: By using less energy after upgrading to Energy Star certified windows, you'll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Milan
Each window installer offers varying services and has different costs depending on several factors.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range anywhere from $200 to $1,200. This is because the cost of window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Milan homeowners $323+ per year after replacing single-pane windows.
Getting free quotes from several companies is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
The first step when considering a replacement is to clarify whether you should get a full-frame or pocket installation.
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 other materials, such as insulation and drip edges, which raise the overall cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation means replacing a window without taking out the entire frame, which is generally cheaper than a full-frame installation.
Your window installation company should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Milan
In our hunt to make your home improvements easier and more eco-friendly in Milan, EcoWatch evaluated dozens of companies before deciding on these. Along with energy efficiency, we evaluated several window installers in Milan and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Milan so you can find the best window installation company near you.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company on this list to make sure its technicians are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If most customers don't have good things to say about their experience with a certain window installation company, 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 the prices of providers, 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. That's why window installation companies with 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 a proven track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Milan, IL Window Replacement FAQs
What is the typical cost to replace windows in a home?
The national average cost of replacing one window is around $600 but can range between $200 and $1,200, depending on a variety of factors. The price is typically dependent on the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which kind of window should I get?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
Do I really have to use a window installation company?
Unless you're handy and have the tools needed to replace your own windows, we recommend hiring a professional installer. The window installation process is complex 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 much safer alternative.
How often should you replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from 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.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all the windows at once is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are damaged or leaky, you can replace just those.
