This may seem like a stupid question, but I have a camp cabin and I'd like to take up the subfloor to look at some joists. We are getting new carpet for it in two weeks, so want to pull up the subfloor to deal with some things underneath. I'm thinking of setting the depth of a circular saw and cutting a section to the joist, the sistering on a new piece of wood to reattach it. Does this sound like a plan? The reason I'm doing it, there is not real crawl space access (lack of space as it is almost on the ground) and I want to check out the condition of the joists underneath and put down a vapor barrier since it is just dirt now.
