#168: Should You Share Your Trade Secrets with Other Craftspeople?

Today's building pros are more willing to swap stories about their crafts than their predecessors were. Is that good or bad for business? Justin Fink joins Patrick and Rob this week and starts off the show with discussions about learning from other tradespeople and about what it would take to get started in blacksmithing. Then the crew dives into several listener questions about insulating without removing siding; avoiding moisture build-up under mats in a basement rec room; keeping cold air out of a walk-up attic; and building a tornado-proof house with ICFs.
