Thanks. Yeah its the usual aging treated lumber. I replaced some a few years ago, now a few more. They were originally nailed and ofc the ends of the boards split, the nails rust away and the top of the joists start to rot. Repairing that, doing some sistering in some cases, and offsetting the new boards as much as possible so the ends are attached to different joists. And using deck screws ofc.
Any experience in cleaning log cabins? Can't power wash-maybe at very low pressure- but no one I have hired ever does it right. Ends up uneven and with streaks and I have to go over it anyway.
What I have always done myself is scrub the logs from bottom up with oxyclean and warm water by hand and rinse, then using a ladder as I go higher and continuing the process(scaffolding would be easier and safer lol). Works great but very laborious and it has gotten really old. I use a tinted Woodguard finish(oil based penetrating) and brush it on, which is also getting old. The result is fantastic but fuck am I getting tired of doing it every few years. The finish last longer than that but with all the farming around here, plus tree debris/pollen it gets dark and skanky looking pretty quick.
