Crawlspace VentilationNote: Radon Mitigation is a
separate field outside of the scope of our work.
In the old days, crawlspaces were ventilated. The idea was that air moving through the crawlspace would keep it dry. Sometimes fans on himidistats were installed to really move the air. Problems arose in the winter because pipes would freeze, not to mention cold floors and high heat bills. In the summer, when the warm moist air contacts the cool crawlspace, the moisture condenses out of the air like on a glass of iced tea. Instead of drying out the crawlspace it would get more moisture. Now, building professionals have decided that the crawlspace is considered to be INSIDE the house. It is called a conditioned crawlspace. We want the crawlspace to be the same temperature and humidity as the rest of the home. If moisture is a problem, keep the water from coming in. Make sure the downspouts have extensions. If there is a high water table, install a sump pump. Insulate the crawlspace walls, not the underside of the floor. Put a heavy liner on the crawlspace floor and wrap it up the walls. We used to do crawlspace ventilation but I spent most of my time telling people they do not need crawlspace ventilation. Except in rare cases, Vent Masters Inc. no longer does crawlspace ventilation. |
