I have a log cabin that is aprox 35 years old, it is a story and 1/2 the front wall of our cabin is in bad shape, we have been keeping up with it as much as possible but we think we will need to replace the front wall sooner than later, it is a small wall aprox 20 ft long and only 10 ft high it also contains a front door, a large window and a picture window. The rest of the structure is in great shape but this wall gets all the weather, how should we go about replacing this front piece? Thanks C
