We are looking at a log cabin that was built in the 1800’s in NC or TN and relocated to central GA. Some of the logs are rotten and the cement in between is falling off. How do you replace whole logs(will they match the others) and what kind of price are we looking at. We noticed that there were blankets at the bottom of all doors for drafts, also, and some of the doors stick at the top and do not at the bottom. Can we put siding or half logs over the old logs? There is no insulation either so
