Thanks for responding so quickly, Ron. I wanted to clarify: the drywall was in piles on the floor when the heavy rain came, three weeks ago, and it was soaked all the way through (huge water spots run in identical places, covering every piece). The insulation, however, was not in at that point. The builder let the drywall dry out, then put in the insulation, and then put up all of the rain-soaked drywall. (We were shocked!) What are the implications if the builder says that "he does this all the time and he's never had a problem"? This is our dream home, and it is part of a development, not our private builder. Our home was the only one which was neglected- "an oversight" they said. Well, last night the rain started again, and my husband went out to the sight to put up tarps on the two sliding glass doors which were not in yet. We have already put $25,000 in deposits on upgrades for this home, so we really need to know how to handle this situation. We love the home, but don't want to be foolish and end up with less than what we deserve. What do you suggest that we do?
