Rotting Crawl Spaces
Crawl spaces are widely known as rotting, humid, dank spaces. There's a reason for this: they ARE, more often than not, rotting, humid, and dank. Unfortunately, what happens in the crawl space does not stay in the crawl space- as part of your home, a rotting, sagging crawl space will eventually affect everyone and every room in the house.
A rotting, sagging crawl space will eventually have to be fixed. Failing to do so will lead to the first floor sagging and caving in, wood support beams and sub floors failing, odors, and an unhealthy home environment. Additionally, if your crawl space is rotting, it's almost definitely vented. Besides being the source of the problem, crawl space vents will also allow in cold air in the winter and warm air in the summer, resulting in a drafty home and higher utility bills.
The "Stack Effect"
This means that you're breathing in the air in your crawl space. And along with this air, you're breathing everything in it, including mold spores, dust mite waste, dander from rodents, odors, and anything else.
Vented Crawl Spaces
Unfortunately, venting a crawl space is, simply put, a bad idea. In fact, it's debatably the worst building policy ever introduced. Crawl space vents introduce outdoor temperatures, humidity, mold, insects, and animals to the space. And because of the stack effect, the air doesn't go out through though one vent and out the other, it goes upwards.
Crawl Space Humidity
As the humidity reaches over 100%, the excess moisture in the air is deposited on anything nearby, including wood, metal, and all other cool surfaces. And as the air rises upwards, so does the humidity. Because humid air is much harder for an air conditioning system to cool than dry air, and this causes your cooling bills to rise significantly.
