Call three licensed tile guys in your area and ask them to estimate the job for you. Don't tell any of them about what you were told, and ask them intelligent questions, and respectfully listen to what they have to say. It won't cost you much, and you'll learn a lot. The durock should have held the tile just fine for many years. It may have been applied right, but may not have been sealed well. Tile is non porous and repels water well, but the grout is porous and can allow seepage of water into the back of the tile and soften the cement. A Sealer is applied to a finished tile job to make a waterproof seal, to prevent such seepage. Durock is a water resistant backer board that is rough, and allows a good bond for the cement, Contractors that don't use Durock use a felt paper that is water resistant, and then an expanded wire lath that is rough and makes a good bonding surface for the cement.
Remember to contact LICENSED tile persons, to get reliable information.

: We are building a house and are ready to have a tiled shower. Previously, we had tile installed over a durock backer board. The tile fell off in a little less than a year. That one was replaced by one that was mudded over a metal mesh. The guy doing the shower now says that the water repelant backer will be fine. What should we do? Is there a best way? He even suggested that he mud on top of the backer board. We need a good answer because we don't want to have to redo it later.
