I've read some of your other posts and I hope I don't come across as a complete bumbling idiot...but I'm not familiar with home repairs. We have a leak in our family room which is located below the bedrooms. The leak in the ceiling to me looks like it has come from condensation from the air/heat vent. We have a tri-level home and our garage is located next to the family room and this vent. We also live in the midwest and have had a lot of high humidity. There are no leaks in the bedrooms located above the family room. Does anyone know if the leaks would be caused from condensation from the air/heat vent? If so, any ideas on how we would resolve this? I cut out part of the ceiling over the weekend because mold is now starting to form. I have two little girls and I'm worried this is going to be on ongoing problem? Any advice you could suggest would be wonderful! Kellie
