There's a margin where rot might not begin, but it will continue. If
you're talking about housebuilding carpentry attached to a damp
masonry wall, then this could be a problem for you. It also depends
on the type of rot you have, and a little on the timber species.
If you're talking about storage damage on timber, then just saw it off
and don't worry. You shouldn't be storing timber at anything like the
humidity needed for rot to be an issue.
Largely though, any timber, including treated, will rot if the
moisture conditions are right. You _must_
remove the moisture to stop
this. Chemical rot treatment achieves little on rotten wood, it's
mainly a way of putting a guard zone around on the good stuff. Fungal
rots will propagate far better on the surface of masonry than on
timber, even though these "threads" might not themselves be damaging.
