AMERICAN HOME INSPECTION

The following article will give you a some idea of what confronts home Inspectors and causes them to dig deep  into the possible problems of each house they inspect.  This is just one of the many unknown land mines that await an inspector when they walk on to a property.  This article was written by Keith Swift, PhD, vice president of the National Association of Certified Home Inspectors (NACHI). Even though most Inspectors will have a fungi-mold disclaimer, the possibility of being sued for it is still very real.

One of the worst cases of Poria Incrassata that I learned about began innocently enough. Escrow had closed on an expensive two-story house, and a painter was finishing the inside of a kitchen cabinet when his brush broke through the surface of a wall. After further probing, it was decided that the cabinets and the countertop would have to be removed to expose a greater area. The new owners were opposed to this at first, but then agreed. But, it didn’t end there. Eventually, the entire wall had to be opened up, and revealed dank cavities and the remains of studs that looked like mummified skin, but which were all that remained supporting some of the second story floor joists. This explained why two bedroom floors were sloping, which no one had questioned before. But, to jump to the end of the story, the owners never did move into their dream home, and a lawsuit ensued with claims that far exceeded the purchase price of the house. Would a first-rate inspector have discovered this? It is possible, because the sloping bedroom floors were certainly symptomatic of movement that should have been recommended for evaluation by a specialist.

The case in which I was personally involved also began innocently enough. During my inspection of a foundation crawlspace, I noticed that a section of cripple wall had been replaced, and deduced that the original one had rotted out, probably because parts of it had been below the exterior grade. The quality of the repair work was poor, the studs were not sixteen inches on center, the nail pattern was sloppy, and shear paneling had not been added, as it should have been to meet current standards, all of which was noted in my report. However, without going into details, the work was relatively recent, and the once negative grading had been corrected, so I was content to describe what I’d seen, recommend that my clients obtain the necessary documentation to confirm that the work was done by professionals, and to upgrade the cripple walls to include shear paneling. Several weeks later, my clients requested that I return to look at a dust-like substance adjacent to a baseboard in their bedroom. They told me that they had wiped it away, but that it had returned the next day. Realizing that I was looking at spores from a fruiting body, I crawled into the foundation space once more and was greeted by the view of the Poria that you see in the long-shot and close-up pictures below. 
 
 
 
It was hard for me to believe how quickly it had appeared and spread. The cripple walls were pristine just a few weeks before. In fact, as you can see, the wood still looks new, and a termite report that was issued three weeks after my original inspection hadn’t noted any evidence of it. Of course, I advised them to also call the termite inspector immediately, because state law actually prohibited me from identifying damage from termites, mold and fungi, and any other wood-destroying organism.

My clients, who were expecting their first baby, were quite naturally concerned about their health and that of their unborn child, but I assured them that to the best of my knowledge Poria Incrassata was not a health-hazard, and gave them the name of a specialist who had educated me about Poria years earlier. They were relieved and thanked me, and I left feeling like a Good Samaritan. A few weeks later, they sued me, the sellers, the termite inspector, both real estate agents, and a host of others for all I know. Their attorney failed to get my name right, misrepresented me as the owner of a termite inspection company, and related a long and overstated account of the pain and suffering and emotional distress that my alleged negligence had caused. Significantly, it failed to mention one indisputable truth, which was that I was the first person to come to their aid, and had made the appropriate recommendation for a specialist evaluation. Of course, their attorney had to have asked them how they became aware of the Poria in the first place, and yet this materially significant fact was conveniently forgotten.

I never heard of the house-eating fungus. Does it occur in all areas of the US?

Where there is moisture, oxygen, the right temperature, and something to feed on, fungi can thrive.  There are over 100,000 different kinds of fungi.  The word fungi includes mold, mildew, yeast, various other things, etc...  (Fungi is everywhere, but different kinds do different things).
