I own a home in the far north, and have a small heated crawlspace under the house. (The house itself is on pilings so the whole thing, crawlspace included is up off the ground a few feet). A section of this crawlspace floor has obviously seen some water in the past and needs to be replaced. I am not having a lot of luck finding out good information (and more importantly things to watch out for) when trying to do a repair to an enclosed and small crawlspace. I am just looking for the benefit of any experience others may have before I dive into this.
I am expecting it to look something like this top down:
1. Main level floor
2. Floor joists
4. plywood floor in crawlspace (requiring partial replacement, last layer I am sure of)
5. Insulation / frame to support insulation
6. Additional layer of plywood
7. floor joists visible on underside of structure.
