I have some water damage to a floor joist, as a result the bathroom sags in one side approximately 1 inch. What can I do to level the floor?
Here are the pics with some labeling: http://imgur.com/a/e3azJ
Now for the details:
House was built in 1986
2 Story Cape-Cod on a dirt crawl, no basement.
Bathroom in question is in center of first floor.
As seen in one of the images, there is a steel I Beam running perpendicular to the floor joists under the 1st floor.
About 2 feet from the I beam is the down drain for the toilet. The joist was CUT some to allow for the down drain to be 12" from the wall when the house was built. We bought the house this year, it appears that in the past there was both a toilet leak around the wax seal, as well as a small pipe leak around the toilet-water supply. This lead to a slight rotting of the subfloor, which I have remove most of the offending area.
The floor is sagging about an inch, maybe a little more, in the one direction. (pics).
The other joists appear to be level from underneath, though I think the one joist is causing some strain on them.
The joist that had the water damage does NOT look rotten, at all. It just sags, like a mild hockey stick. I assume some of its weakness comes from the cut.
We're looking to install 1'x2' ceramic tiles in this bathroom, and I believe that joist, right there, has the weight of the shower, toilet, and load bearing wall that supports the 2nd story on it, which is why it has deflected so much.
There is not much give, if any, if I jump on the floor, or try to see if its weak. It more looks like a strong piece of wood that has deformed over time.
What would be the best path to repairing this so we can install tile? I will most likely remove the subfloor completely in the room, from wall to wall, and recut the ply, after leveling the joists.
Thank you for any suggestions!
