This is high end lumber on a custom home built in 1995. We began the siding maintenance in 2004. Therefore, in the 13 years since we got the job, this was our fourth time adding a maintenance coat to this South facing wall. From the top, you can see that the staining process is underway. So yeah, 4x in 13 years due to the heavy sun exposure. Many parts of this beautiful home in Live Oak have received only one coat during the past 13 years. Another example of “as needed” exterior wood maintenance. The alternative to “as needed” maintenance is waiting every 10 years to stain the entire home. Bad idea!!
