I'm slightly concerned about the deck skirting on the elevated side and
back decks, since it clearly violates the wood/ground contact rules.
It's just 1/4" plywood and I don't care too much if it rots out and
needs to be replaced periodically, but if it's a significant termite
issue then I'd like to consider some alternative design.
To the extent reasonable I'd like to cat and rodent-proof it, because
the deck crawlspaces and the house crawlspace are contiguous. (You can
see some tunneling has been going on to the left of the steps.)
So what are the usual (or even unusual) approaches to this issue? I can
think of a few home-brew concepts but there must be some standard ways
of dealing with it.
FWIW, the house is in California's central valley, was originally built
in 1930, added onto twice, and completely remodeled just prior to our
acquisition 18 months ago. I have no idea how old the decks are.
