Our builder forgot to cover the vents in the roof and let our new home get drenched during the last rain storm. We were shocked when he used the water stained drywall all over our new home- literally every piece is water marked. He also let our fireplace stand in water, and the a/c evaoporator coil was dripping wet. We don't work in this field, and need your advice. Will this harm the integrity of our home in the future, and if so how?
