Re: Why is my crawlspace dirt moist?
It may be that groundwater is a normal occurrence where you are. As DJ said, install a vapor barrier on the ground in the crawlspace. Make sure that foundation vents are kept open, especially in the winter. If your floors are not insulated, insulate them. In the Seattle area, you will have greater moisture problems in the winter than in the summer.

I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
