There are times where you cannot find the words to describe the insane things you come across in this business. This is one of those moments. Someone cut through 90% of a joist to run a flex vent. Then just to ensure the structural integrity of the home did not suffer used an entire can of spray foam to shore up the supports. I’ll bet dollars-to-donuts that this project started by someone saying “hey dude, here…hold my beer!” Albert Einstein is quoted as saying “Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.” We could not agree with you more Al!
