115 yo spruce log cabin – leveling and log replacement

Great questions. It’s tricky to estimate such a project without seeing it but if I were you, I would consult with a reputable contractor AND log home repair specialist in your area. So many factors go into cost and project course of action. In our area, the log home repair specialist would replace the logs while the licensed contractor would do the rest of the work. Sorry we couldn’t be of more help.
