I am pricing a job of grounding outlets in an old house. The house is 2 story and has all (app 75) the outlets cut into the baseboards. Two questions. Am I better to remove the box, install ground wire and use a rework box for the new outlet. What is the best way to get to the second floor outlets. Do I remove the box and fish a ground down to the box(hopefully no purlins). There is a wide open attic with walking space. There is a old plank flooring down that can be removed if necessary. I haven't grounded outlets in a job like this before.
