I purchased my current home 3 years ago, the house is all of 18 years old. During installation of a new front deck, we discovered a fair amount of water damage to our Door box, and the wall adjacent to the box. We later learned the house had sustained storm damage, was "fixed", but apparently sealed up with wet wood; or so we're guessing (FYI - I had to replace the entire roof 3 months after I moved in, so if it were a bad roof, we've resolved that).
One of the joists between my first and second floors has rotted completely out at one end (about 2 feet of it). The subfloor above has also started to rot. My question is how much of the wood, the joist, do I need to cut back before splicing in a new piece?
What about treatment(s) for the remaing "good" wood near the damaged area?
If additional information is needed, let me know (just trying to keep this short).
