Were they drunk or something???  We've had bad carpenters over before, they installed this entire sheet of wood panel on the floor, and A: it was crooked, B: they didn't install the lower softener so it was physically lower than the kitchen's wood, and C: they really did a number on some of the walls with their equipment.  Now I don't expect a 100% amazing job or anything, nobody's perfect, but DAAAAMn, at least have some respect for people's houses ya know.
   -I think there's some offices you can contact if these people don't offer to fix all of the wood they messed up, and you could probably get a nice settlement from them, like a new free installation of wood with guys that aren't gonna mess it up.  Just a suggestion.
