My daughter and family have an amish built log home was built 3 yrs ago they are now getting mold in windows and frost on the inside of their daughters room why and what do they do about this
It’s hard to say without seeing it, but it could be that there are gaps between the logs allowing moisture in or there could be too much humidity in the house. It may need to be caulked or chinked on the exterior first to see if it helps.
