And, for security, our doors have a lovely, color-coordinated locking handle.

Why Purchase Your New Sliding Patio Doors from Us?

We want to make sure that your new sliding patio doors perfectly fit your backyard oasis. The Window Source of Mankato provides a range of ultra-durable, fashionable, and reasonably priced configurations and custom sizes.  

Depending on the layout and design aesthetic of your home, you might wish to select from a variety of types for improved strength and longevity. We have two-, three-, and four-panel variants with vertical stiles strengthened with aluminum and steel. We also provide a complete selection of Low E insulating glass alternatives that satisfy the most stringent standards set by the industry for the ENERGY STAR® Most Efficient program. Tempered safety glass is used in the construction of each sliding patio door in order to meet or exceed code requirements.

The security of your loved ones is paramount when it comes to security. For your peace of mind, we offer single, dual, and multi-point locking systems on each of our sliding patio doors. A secondary, foot-operated security bolt that creates an ultra-safe atmosphere with improved ventilation and air flow is an additional option. 

Our doors also have moving panels that glide silently on huge twin ball bearing rollers, which guarantee years of trouble-free use. These steel rollers effortlessly travel on a stainless steel roller track that is enclosed inside an extra-strong threshold.

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.
Andrew Ehlert
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!

Down to workmanship, Ben Ryman was amazing installing my windows. I felt very comfortable with everyone who was Involved. If you want excellent quality windows, customer service and installation for the price, I highly recommend The Window Source.
Deanna Liddy
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. Ben installed the windows and was polite, efficient and so knowledgeable. Professionalism from top to bottom!
Jeanne Marriott
Had several windows including a slider door and large picture window replaced. Ben and Andrea were very pleasant to work with. Very professional. Cleaned up everything while they were working and after as well. I am so happy I went with Window Sources of Western Michigan.
