 Now, the third thing that you can do is just to be very careful with your outdoor drainage maintenance. So by that, I mean make sure you have gutters on the house, that the downspouts are discharging away from the house, and that the soil around the crawl space perimeter slopes away from the house. By trying to keep that water away from those walls, you'll reduce the amount of moisture that's building up in the crawl space. Does that make sense? It does. I think I've got all that covered at this point. What about a heat humidifier? I've been told that's the next step.
