i own a 30 yr old log home.i have some soft(rotted)right next to my wall unit AC.i believe either water is coming from the unit or splashing off the roof on to the ac and the wall.there are a few logs involved.i have never heard of half logs .how do they work and how would i know if i could use them or have to replace the whole log?can i send you pictures of the problem or is there another site i could send them too?thanks
