Just purchased this 1950's ranch that had some pretty extensive termite damage to the subfloor. After repairing the subfloor I have moved onto the fire place and surprise surprise, more termite damage to the load bearing wall that separates the living room from the garage. I have attached some pictures of the wall. I would like to replace the double 2x4 top plates that the ceiling joists are resting on, but want to make sure I am taking the correct approach to this repair. The ceiling joist in the living room run parallel with the wall I want to repair. From what I can tell the ceiling joist from the garage rest on the wall that I want to repair ( i think 6 joists rest on the wall). My plan is to build a temporary wall in the garage to support the load of the ceiling joists while I sawzal the top plate out and replace with new 2x4s. Do this sound correct or am I way off here.
