I feel your pain, I just had central air & heat put in and at the same time tiled my den. The air and heat was a breeze, they finished before the tile guy. The grout in the tile is the wrong color, the mess he left was horrible, the tile company said it's not their fault the grout is wrong, they just went by the color on the sack. We are still negotiating on the balance of the tile job, he said they would change out the grout, but holy moly the mess again, I don't know what I'm going to do yet.
