Abstract
A method of replacing an existing fenestration unit secured in a rough opening in a wall having a finished exterior includes releasing an existing fenestration unit from the wall by cutting around the existing fenestration unit, including cutting into the finished exterior of the wall and through a perimeter portion of the existing fenestration unit to release the fenestration unit from the wall. The method also includes removing the existing fenestration unit from the rough opening in the wall, installing a water management system along a sill of the rough opening, and inserting a new fenestration unit into the rough opening. The new fenestration unit is secured in the rough opening.
