I am considering purchasing a cypress log home that was built in 2006. Not sure that anything was ever done to the outside logs and was wondering if you need to treat, stain, etc cypress logs. The exterior finish looks great, but a couple small areas look like they are fading. The house itself is pretty well protected from the sun with tree cover. Also some of the interior is aspen wood. It does not appear to be finished in any way and really looks great. Is there any need to finish this w
