Hello, My name is Jacob and I am new to this forum. I have attached a couple of pictures of a room that I am renovating. I had a suspicion there could be water damage at the corner of the house because the gutter downspout on that corner had gotten clogged and burst its seam, leading to some water damage on the exterior trim. When I pulled out the room's carpet and the baseboard trim and cut out some drywall, I found that the sole plates at the corner are rotting away (and still moist.) My house was built in 1975 and seems to be a normal platform framing. I assume that I need to replace parts of the sole plates (probably about a foot in either direction) and also the corner post, which I haven't actually seen yet but I assume the base of it must be rotting just as much as the sole plates. My main question is this - how do I go about properly reinforcing the walls before I replace the corner post? Does the corner post bear more weight because it is on the corner or do I just consider it to be similar to another stud? My carpentry books give examples for putting windows or doors in an exterior wall and show how to put up a temporary stud wall for reinforcement. But they don't mention my scenario - having to replace the corner post and sole plates. Any suggestions would be more than welcome since I am still very new at this. I hope my pictures make what I said more clear.
