These photos are of a homestead built in the late 1800's. The old finish was corn blasted off, the chinking was removed, and decayed logs replaced. The building then was stained and chinked. 

These photos are of Saint Peter's Mission, the second oldest mission in Montana. The building was built in the 1800's. The mission was jacked up and treated timbers were placed as a foundation to level the building. The old finsh was corn blasted off and chinking removed. Penetreat, an anti fungal treatment was applied. The building was white washed and chinked.
These are photos of a home that had some rot in a few of the logs. The rot was removed and the remaining logs were treated to prevent further decay. Custom log siding was installed, then stained and caulked to match the exisiting logs.
