The Facts
The theories behind the control of humidity in crawlspaces of buildings have changed over the years. It has been previously believed that the proper way to control humidity has been to utilize foundation vents to increase air flow within the crawlspace. The increase of air flow was designed to allow humidity to escape through the foundation vents to the outside of the building. Building codes required installing foundation vents according to the size of the crawlspace. Building codes have now changed throughout the country to allow for “conditioned crawlspaces”. A dehumidifier is a must to condition the crawl space.
The foundation vents that were originally designed to eliminate humidity actually help to increase the level of humidity in most crawlspaces. Instead of allowing humidity to escape, the foundation vents allowed hot, humid air in the summer to enter the cool crawlspace. The humid air then condensed on the cool water pipes and air conditioning pipes and dramatically increased the level of humidity in the crawlspace. Indoor air quality is at risk when this condition is allowed to exist.
The increase of humidity created conditions suitable for mold and fungus growth. “Conditioned crawlspaces” eliminate excessive humidity in crawlspaces and help eliminate the conditions that allow for mold and mildew growth. We are experts in designing and installing full crawl space encapsulation and dehumidification. Basement dehumidifiers and crawl space dehumidifiers are available in sizes that are matched to each individual application according to square footage and structure. Encapsulation and dehumidification is not a form of mold remediation.
