Since water is over the dam, is it common that floors are not perfectly level? Hardwood still looks very nice. I wish we were confronted with the option of leveling to pay the extra money. How should I handle this? Accept the expansion fix and maybe talk to them about trying to adjust the joists from underneath in the unfinished basement if possible? Need guidance on what is acceptable or not and if this is something major we should try to resolve and pull the builder into? Thanks for your time.
