How often do you have to stain the exterior and interior of a log cabin?
The interior is typically once. The exterior should be washed and clear coated every 2-4 years after the initial staining, depending on your weather and setting. You may have to give the stain on the heavy weather sides a little light spray every 4 years and then clear coat. If you keep up on the maintenance it will save you money over time.You should budget $1 per square foot of living space / per year for a professional to do the upkeep.
