How do we fix this without redoing the whole floor? Every search term I’ve tried on Google does not lead me to helpful blogs or YT videos. Unfortunately it’s a flipped house and they must not have fixed the subfloor in this room before laying the flooring because we can feel gaps all over, and as evidenced the flooring broken in to one spot that was clearly not supported. Not trying to spend an arm and a leg as we’re hoping to just be out of this house before too long.
