These are some pics I took in the vented crawl space of a 4-year old home in our area! There's all sorts of gnarly organic growth, insulation is rotting and falling from the joists, the floor above is collapsing in two places due to wood rot and the entire living space wreaks of musty odors. The unfortunate homeowners face a hefty bill for remediation and structural repair. This all could have been prevented. Had a basic measure of common sense by those who ran the HVAC ducts through the trusses and then installed insulation underneath been deployed in conjunction with an effective sealing and conditioning of the crawl space, there would have been no reason for us to visit this home. Instead, they created a condensation-rich "dead zone" that was exacerbated exponentially by the constant intrusion of humid outdoor air through the foundation vents and ground moisture via exposed earthen crawl space surface.
It is imperative to know what is going on in your crawl space before it affects your health, your home and your wallet!!!
