Same here... my walls are brick that need to breathe or they will crack and crumble within years if sealed up too tight.
Same goes with the cinder block foundation. If insulated, it moves the freeze/thaw interface inside the block and then you end up with a failing foundation.
I have to clean the eaves of my house myself because nobody I hire will believe me that you can't point a pressure washer at the eaves without water getting inside the walls. "I'll just avoid the vents" doesn't work when you can see daylight between the roof and the wall all around the house.
