No, I don't think he's saying anything to get me to back off. I think he was being really sincere about trying to rectify the situation. He just said we were going to have to talk to the sub to see if there was something we could do to try and fix it. But I know we paid extra for the upgraded tile installation and we feel we didn't get it. When I was looking at the pictures I posted more closely, I noticed even more mistakes. I ended up telling my husband I think we might be better off if he fixed the tile himself. But if he has to fix their mistakes, I think we need to offset the remaining balance that we owe on the pool the day the plaster goes on.
