Window Depot of Mankato & Rochester came through in a pinch. I had just about enough of the salesman from two competitors and was completely fed up with the lies and false discounts they kept pushing on me. Thanks to a friend who knew I was fed up gave me a # to Bob’s Construction our Local Window Depot of Rochester. I called the owner Kelly Madson and explained my situation and he said I promise you we will make you happy and you’ll pay a fair price….With that being said Kelly and Jaime came to our house a day later and did everything right…first they educated us in the current technology put into window manufacturing. Then they instructed us on the differences between double and triple pane windows and explained the proper installation and operation of Window Depot windows. So after showing us a price that was almost 30% cheaper than the competitors for triple pane windows our mind was made up. Three or four weeks later we got a call to schedule our install and three days after that call our install was complete and all debris was removed and the clean up was meticulous. We highly recommend Bob’s Construction our local Window Depot to all of our friends and family.


Megan & Roger

Triple pane windows for the cost of double-pane is what intrigued us to place the call to Bob’s Construction our Local Window Depot. That was the best phone call we ever made. The entire process from the first call to final installation was about seven weeks or so but we are extremely pleased and absolutely love our new custom manufactured windows.

Sam & Olivia
