We have encountered a problem with constant humidity in the basement of our home. Since it is located right on a lake we used the special drywall normally used in bathrooms, however, the moisture still builds up so much that the doors are corroding and the ceiling and floors have water stains. Water can regularly be sopped up with towels. What else can we do? Does a special ventilation system have to be installed?
Any ideas are greatly appreciated. Thank you!
