There's an alternative to replacing the wood; there are several ways to repair it using resins. One approach involves four steps. First, any loose material is removed, but intact, soft material can remain. Second, a thin resin is applied to penetrate deeply into the wood, seal it, and provide a solid surface. Third, an epoxy putty, often filled with wood fibers, is used to fill and restore the original shape. The last step is sanding and finishing. This link illustrates the process: [LINK] . A simpler three-step process is to grind away the rotted wood down to good, solid wood.

I am hoping most of the damage is surface, but in order to to repair the joists w/o full replacement (as recommended here [LINK] ), I would follow the below laid out plan. In addition to the joists, the header joists also has small dry rot area. That would be a straight replacement of the said header joist. I would appreciate any feedback on the process. My brief research shows that best practice is to repair the
