I know from 134:11 in the Kitzur Shulchan Aruch that one may assemble a Sukkah during Chol Hamoed. May one disassemble a Sukkah during Chol Hamoed in order to prevent the Sukkah from being damaged by, say, a hurricane?
I saw the title of that and my first thought was "you left it up all winter and into Pesach?". :-) No, not what the OP meant, as is clear in the body. (I wasn't considering that there might be reasons to take it down during Sukkot.)
