The Nineteenth Hole

Approximately 3 years ago, we purchase a brand new spec home. The house is a tri-level house, with the basement portion approximately 1/2 below grade. When we purchased the house, the basement was completely finished, and only one room (the furnace room) has exposed 2x4's with insulation and plastic covering the exterior walls. Recently when a Satelite Dish installer pulled back some of the insulation to pass the cable wire through, he noticed that there was ice and moisture on the wall. Pulling back the insulation revealed that the entire wall was infected with mold. I contacted the builder and they are currently working to remove the mold and reseal the room, but I am wondering if I need to have them do more than that. Do I need to have the rest of the house inspected (difficult because it is all behind finished sheet rock)? They are removing mold from the inside, will there also be mold on the outside? Once they do clean it will the be permanent damage to my house? Thnks 4 ne help.
