On today's blog we will discuss when you will need a vent fan and dehumidifier in the crawl space. How we at Crawl Space Ninja determine the best way to install them. Why both are crucial to crawl space encapsulation.
Crawl Space Ventilation Fan
The reason for the vent fan is to move soil gases that might be present in your crawl space out. We are located in East Tennessee where there can be radon present. This doesn't mean you have a radon problem but other gases can also be present so we like to take precautions.
Crawl Space Dehumidifier
Remember this is only the case when the dehumidifier is a standalone unit within the crawl space. That means that the dehumidifier will not be pulling in air from the living space above.
The only thing you have to keep in mind is that one vent fan can cover up to 5,000 square feet. Make sure crawl space vents are sealed properly. If you have a larger crawl space, multiple units may be needed.
