I have a client who wants me to install fiber cement over his existing T1-11. I'm concerned about rot issues that would come with this. I guess another contractor suggested just cutting the bottom off where its starting to swell and replacing that portion them just cover up. Is this a good Idea. Is there typically already a vapor barrier behind the T1-11, and would putting another layer of house wrap cause problems. Any advice is much appreciated.
