I have a house that the previous owners wife wanted sheet rock in the bedrooms of the home. Had 30’of logs to repair and found out that their contractor put plastic up against the log and sheet rocked right over the plastic, not allowing any air space between the two surfaces. There is a white fungus/mold all over the plastic and logs and the logs are dry rotted from the back side out. What started as 30 foot of log replacement now looks like the total wall(s). Is there any treatment that wil
