My father lives in a 100+ year old home that he purchased 7 years ago. In the last several years he has discovered that there is a spring under his home that is leaking into the basement and causing mold throughout the house, especially the basement. The mold is causing him health problems, especially since he already has COPD. In fact, he has developed a fungal infection in his lungs. Is there anything he can do since he cannot get rid of the mold?
