 The subfloor is rotten where the bathtub was, and one floor joist has termite damage. I dealt with the termites, but I'm wondering what is the best way to repair that damaged joist? Can it be sistered? I mean, that's really kind of your only option here, right? Well, I'll tell you, when I was a home inspector, Leslie, I used to do this all the time. I would go into these bathrooms and check for rotted floors. I would put one foot on one side of the bowl and one foot on the other side of the bowl.
