(WXYZ) - Patients and their families had quite the surprise when they looked outside of their windows today at C.S. Mott Children's Hospital.
They were greeted by superhero window washers.
Armed with squeegees, a team of men dressed as superheroes propelled off of the roof to wash the windows on the 12-story building.
The windows of C.S. Mott Children's Hospital are washed four times a year.
