Our 1930's house has damage to the subfloor and joists under the bathroom. A while back (before we owned the house) there was a water leak and the floor joists have rotted away, causing the subfloor to sag. This has caused the tile floor in the bathroom to crack significantly.
I have looked at this from the crawlspace, and there is damage to 4 joists, 2 on each side of the toilet.
In the past 6 months the cracks have increased in our tile floor so i'm looking for a short term fix (we are planning to remodel our bathroom at some point and rip out the tile floor and also redo the sub floor/joists.
For a short term fix, i'm planning on nailing on new floor joists next to the damaged ones, and extending them all the way out to the band. I may need to jack up the floor a bit to get the joists in.
Will this be a good short term fix? I'd appreciate any comments / suggestions.
