Hi I am in my 2nd month now. My husband and I live at his parent's old house. We found a few cracks in the basement of the house. My husband thinks it's better to do exterior waterproofing in the entire house. But I am scared if any chemicals involved in the waterproofing procedure might affect my baby's health if I inhale it. But my husband thinks that it should be done now as it's going to be more difficult once the baby is born. What do you guys think?
