Do you see anything wrong with this picture in a New Orleans crawl space? There is no light shining through the sides. So there is no ventilation at all on the front half under the home. This can cause a buildup of mold. It is South Louisiana, right, we have high humidity. Fortunately, the back half of the home was very well ventilated so that was helping the front half, and I didn’t see mold on the joists and subfloor. But the contractor should not have built it this way, so I wrote it up in my report as a deficiency but seemed to be performing well anyway. The higher humidity and dead air was apparent when I crawled into that section though. Home inspectors are quickly aware of this when we get attacked by the mosquitoes in that area. Then we have to giddy up, because we are a sitting duck under there. That in turn hurts the thoroughness of the inspection in the crawl. We just do the best we can but when small animals are injecting a serum into our bodies to thin our blood and suck it out, you can’t help but move faster. I mean they do carry diseases. I sometimes write in my inspection reports that mosquitoes “limited my inspection”.
