Please don’t take this wrong I just want to make sure I learn right and we are all on the same page. According to what I posted below dry rot does exist in homes and they even called it Dry rot during the show. The Dry rot problem became very expensive for the young man trying to flip the house plus the city inspector wouldn’t pass the construction inspection until the dry rot and the plumbing was fixed.

Dry rot is a disease of trees, often caused by the fungal species Merulius lacrymans, Poria incrassata, and/or Serpula lacrymans. The fungus invades and deteriorates the cellulose in the woody parts of the tree.
It is probably better known as an architectural](http://en.wikipedia.org/wiki/Architecture) problem, as it can continue destroying wood after a tree has been processed into **lumber](http://en.wikipedia.org/wiki/Lumber), causing instability and collapse in houses, ships’ hulls, and other wooden structures.**
It is known as ‘dry rot’ due to its abililty to affect wood with a very low moisture content (typically 20-30%). It forms large orange/brown fruiting body at the point of moisture and will send out white tendrils into adjoining brick work as it seeks more wood to infest.
Dry rot can also refer to anything that “rots” without the presence of moisture, such as when rubber tires crack and begin to disintegrate. In addition, the term can be used as a metaphor for grave underlying problems within a large organization (such as political corruption in government or low morale in the armed forces) that show no symptoms until a sudden, catastrophic failure.
