I had an electrician over yesterday and they ran BX and a flex conduit for a TV I want to hang over my fireplace. I was examining the notch they made in a stud immediately next to the chimney masonry and I'm concerned that it is too deep. The member is a single 2x4 and the notch depth is slightly over 2", so I would consider this stud compromised. Complicating this further is that there is pretty much no way to adequately install a stud shoe on this thing because it is directly next to the masonry of the chimney.
Directly behind this stud is what I believe is the sheathing, it's hard to tell because it's full of old insulation, but there is some kind of lumber there.
Should I be concerned? I've already contacted the electrician and am waiting to hear back. I don't know if being near masonry helps or hurts and whether my house being brick on frame matters (I suspect it doesn't).
