Dear James: The grout in our master bathroom shower stall is looking pretty bad and some pieces are crumbling. Do I have to remove some tiles, or can I just fix the bad spots and regrout?—Angie M.
Dear Angie: In most cases, you probably won’t have to remove any tiles. As long as they are still in good condition and only the grout is falling apart, you only have to fix the grout, not all the tiles. Old, worn-out grout can allow moisture to get through the tiles and ruin the walls. If your shower walls are already at this point, you probably will have to remove the tiles to rectify the backer board.
