Awning and Casement Windows in Mankato

Our Industry-Leading Vertical Casement Windows 

You must check out our casement window replacements if you want high-quality work and durability that leads the industry at a reasonable price.

They include strong mechanics and heavy-duty hinges to ensure years of maintenance-free operation. Our casement windows at The Window Source of Mankato have a mechanical crank system and open to a full 90-degree angle. Plus, you can count on the multipoint locking system to keep your home safe and secure in addition to excellent airflow.

Or Try Horizontal Awning Windows Instead

These horizontally oriented awning windows function similarly to casement windows, opening from the top or bottom of the window using strong hinges. Our awning windows at The Window Source of Mankato offer all the benefits of casement windows and, depending on where they are situated, can also serve as the ideal passthrough window for your upcoming outdoor gathering.

Where Do Awning and Casement Windows Work Well?

Anywhere there is natural light, or you want better ventilation. Our casement and awning windows are the ideal choice for confined spaces. Consider how much simpler it would be to open a window in a bay or bow window, or above the kitchen sink. Even in smaller areas, you can easily open and close the window with the single crank handle. 

Our superior casement and awning windows are nearly maintenance-free and withstand Southern Minnesota’s harsh weather conditions. These casement and awning windows won’t need to be painted and are made of the highest grade weather-resistant vinyl. They also won’t chip, crack, or peel.

See What Our Customers Are Saying About Us

We just had The Window Source install 6 new windows and a sliding door. They look fantastic! All the windows are triple pane and are very efficient and high quality. The fact that they were about 1/2 the price of the competition was a sweet bonus! Aaron and his team did a great job and showed up on time and were very professional. And no high pressure sales tactics – very refreshing. I would recommend The window Source to all my friends and family.

I am so happy with our new windows and new door. Ben installed everything for us, and he did an amazing job! I cannot say enough about the installer, he was on time, professional, fast, and his quality of work is superb . His work ethic is none like I’ve ever seen. We will definitely be using The Window Source again in the future!

Great experience even given the unpredictable product delivery industry this past couple of years. Lots of communication and they were there when they said they would be and finished on time.
