I am repairing my bathroom subfloor which had a leak from the shower step that caused the floor to rot. So far I have demoed the shower floor and will demo the remaining bathroom floor and install completely new 5/8" plywood. It appears that not too much of the floor joist have any damage other than a single one which has visible water stains but no rotting. I want to sister another joist to this one just in case, I will do one as long as possible, end to end. My problem is as you can see from the image, the joist hanger of the original joist will hinder the new joist from having a firm connection with the beam. What is the recommended solution to this?
