As the saying goes, the definition of insanity is doing the same thing over and over and over again, expecting different results.  By that definition, the home building industry should definitely be deemed insane.  So if we know that typical building methods are dangerous, why do we keep allowing it to happen? Probably because of the cost increases...either perceived or real. So lets have that conversation today.  Then from this point on, I want you to ask these questions to your contractor or architect.  There is a healthier alternative for just about every material used in home building today. We just need to start asking WHY.
