We are considering buying a Pan Abode Log home in Upstate NY. We noticed that all of the corners on the outside of the house were caulked and we noticed water marks in the corners on the inside of the house. Is caulking a normal required maintenance step on one of these homes? If so, how oftem and does the old caulk need to be removed first? Could the problem just be that the owners did not tighten the logs with the threaded rod/cranks on the outside of the house?
