Hi, thanks for the responses on my previous post. I have now dug out "most" of the affected timber and will now be inserting new wood where necessary. However, I cannot get to some of it but I have found the leak and have sorted it and its drying nicely now. If I can keep this dry will the rot I cannot get to just stick around ? or will it continue to spread ?. I am working on the assumption that wet rot stops spreading if the moisture source disappears. Thank you.
