  2. Our mildew smell is strong in our basement. The basement is 1200 sq ft so it’s hard to tell from where it originates. We had a small leak from a toilet above, but we replaces the ceiling tiles and checked for moisture. We’ve had trays of baking soda out for weeks. I could probably get rid of the smell, but I am afraid of getting mold.
