But I Never Go In My Crawl Space, So Why Should I Care?

Your house is one building. It operates as a system. You can't have one part of the building that is sick and another part that is healthy. You can't rationalize that since you never go in the crawl space you aren't affected by it.

Crawl space air is in your building envelope. This is caused by -the stacking effect! As warm air rises in a home it leaks out the upper levels.  New air must enter to replace the air that escaped. This creates a suction at the lower levels to draw in replacement air. What 'stack effect' does is create an airflow in your home from bottom to top. So air from the basement is drawn upwards into the first floor, and then to the second floor. Building scientists say that up to 50% of the air you breathe on the first floor is air that came from the crawl space. Therefore, whatever is in your crawl space air is in your house and affecting you, whether you spend any time in the crawl space or not. If there is high humidity downstairs, there is higher humidity upstairs than there would be otherwise. If there is mold in the crawl space, there are mold spores upstairs. 

Having a damp environment in your crawl space is very unhealthy and destructive. Mold thrives and reproduces by producing airborne spores by the millions, and some mold can be toxic. Once mold has grown large enough to be recongized visibly, a much more serious issue exists somewhere in the building envelope. The solutions necessary to properly correct this type of mold ALWAYS will involve identifiying the source of the problem - a leak, condensation, or high relative humidity. The solution is to make the environment dry.

Healthy Spaces proudly uses CleanSpace, a 20-mil thick plastic liner that can be fitted in your crawl space or basement to completely isolate your home from the earth. This dramatically reduces the humidity level in the air which, when combined with sealing outside air and dehumidificaiton, will eliminate mold growth and rot from your crawl space and make the whole house healthier.
