I had same problem with a house built in 91 had to tear it out 4 ft up and replace wallboard and base tile. I was not impressed with the building techniques used they were to code but for another 40 dollars it could have been done to last. Cement board in the walls instead of blueboard and using cement blocks for the riser instead of pressure treated lumber as well as a one piece marble cap instead of tile would have prevented the problem of water entering through the tile and wicking down the 2x4's into the wall. Don't know what techniques they have been using lately or if you can get villages to pay for it but I can't imagine being able to go back after 5 years. Make sure you get it done right the second time. Good luck.
