Door on sealed crawlspace
The previous owner of my home had the crawlspace professionally encapsulated. It was very expensive and they did a good job except for one detail: they left the original, leaky, rotten, plywood door. This meant that the “sealed” crawlspace was not very sealed at all.
I’ve taken a stab at building a custom door with the goal of making it durable, rot-resistant, and air-tight. I think I have mostly accomplished this, but I have identified a potential problem due to the unprotected nature of a crawlspace entrance: because the door is so close to the ground, there is a lot of splashback from rain. There is a roof overhang, but that is too high to provide any real protection here.
I have attached a couple of photos showing how much splashback is on the door after a hard rain. You can also see that water gets on top of the threshold and sits there. The door fits tightly right now, which means the bottom of the door is sitting in this water – not good. As it stands, I think the new door will rot out quite quickly.
Any ideas on how to alter my design to result in a long-lasting door?
