I have a log home which was built with pine logs and sealed with Menco stain. The home and coating is 3 years old. This year the surface on all of the exposed sides got a black stain on it which was more predominant the lower down the wall you come. What would be the best way to determine what is causing this stain. I have read about 4 or 5 things already that can cause black stains. Thanks.

You either had it power washed or the logs were still not dried properly when it was stained. More than likely it will have to be stripped to get the black off the logs. Hard to tell without seeing it. Try washing it with some Perma Chink Log Wash and see if you get any results.
