I just started replacing clapboard on my house only to find a major infestitation of carpenter ants after removing some of the sheathing where it had rotted away from the runoff from a drain spout. Yes that will be fixed.

One of the studs behind the sheathing was damaged by the ants, but the carpenter I had working on the house said the 2x4 stud was still good; that the major 3.5" of the stud width was still good.

With the extermination completed, he will be replacing the sheathing, installing Tyvek and new clapboard.

Given there was some damage to the stud and one of the garage roof joists for the attached garage, is there anything else that should be done with the damaged wood to avoid its further deteriation over time?? Or is buttoning it up as planned sufficient based on my carpenter's recommendation?
