“When I work with insulation contractors and I ask them how often they do Grade III work (insulation installed with “substantial defects,” according to RESNET standards), they always reply ‘never.’ Whenever I am a part of or hear these conversations, my mind moves to another conversation, where someone told me that the difference between an apprentice and a master is that a master knows how to mask their mistakes. This makes me wonder, with so many masters of their respective crafts, what is being covered up?”
