Ho Hum, we have some heavy driving rain the other day and found damp patches on the inside of some of the logs. Looking on the outside it looks as if there are cracks that extend along some of the logs for a considerable lenght, and in some places go all the way through the log. This cracking or “checking” is normal as the logs dry out. We experienced similar problems with water penetration in our earlier log house, and it sometimes needs and exact combination of rain and wind direction for the pesky crack to be found and the water to be pushed through it. So it really is a one or two day a year issue, but much better to discover it now, while we can fix it.
We contacted the North American log house supplier and they will be sending us a repair proceedure they recommend to deal with this.
