In the center of the below picture, I recently had a cable installer come out and they drilled a 1" hole (effectively cutting the stud) right through the middle of the stud with the electrical box on it! Since this is a load bearing wall, I'm trying to figure ways to repair that stud.
I can see that there is a sistered stud on the left of the damaged stud, but it doesn't extend all the way to the floor. What is the purpose of this stud? Can I fix the damaged stud by mending the sistered stud to extend all the way to the floor?
