Well, maybe its not replacing and only repairing and I'm not doing it. My neighbor's laminate kitchen countertop is coming up horribly. So bad, the builder is having someone come out (they've been in the house 4 years!). However, the repair guy says he'll have to remove some of the tiles from the backsplash to fix it. The tile is grouted, but only caulked where it sits over the countertop. Is that absolutely necessary? I think there's a million ways to do it without breaking the tile, including pulling the entire countertop off and setting it on the floor. Comments? Need more information?
