On the vapour-barrier topic...
I have a mass-produced, 1980s Calgary house in which I'm sure the vapour barrier was poorly done and probably not sealed. Has anybody here actually torn out walls in a house of this era and found significant mold problems? I'm kind of crossing my fingers here and hoping that, outside of grow-ops or heavily-humidified houses, our climate is dry enough that cavity moisture isn't a serious problem.
Stories?
