Structural Floor Joist Damage
You can see how badly this floor joist is damaged
and if you look to the right in the picture you can see the tub trap and
drain.
The structural floor joist is completely destroyed and will definitely
need to be replaced. Sometimes when I run across situations like this, I
wonder how many years the floor would have lasted until it completely
caved in.
This floor joist was damaged by a leaking bathtub and tile shower
surround.
