rotten wood on corner post

cord12 | Posted in General Questions on

Hello, I have a corner post (3 sandwiched 2x4s) of our garage where the bottom has some rot (roughly 1/5th of the longways width of two of the 2×4 are rotten from the mud sill up to about 6″ on the post).  I know how the water was getting in (tear in the house wrap). What is the best long-term fix for the corner post. I was thinking remove all the rot, treat the balance with wood preserver and then “sister” in some additional support. I’m going to liquid flash the new sheathing once the corner post is sound. Thanks, David

    The best approach would be to replace the post entirely. If you have truly fixed the water infiltration problem, sistering the post would likely work as well, but it wouldn't be much more work to just do it right.
