Were homes built better in the 1970s?

In this episode of The Ground Truth, Erik Jensen dives deep into the anatomy of a 1970s build to deconstruct a controversial reality: your "leaky" old house might actually be safer and more durable than a brand-new home. Modern houses are often built like airtight "plastic boxes" that rot from the inside out at the first sign of moisture. In contrast, 1970s homes were built with natural materials—trees, rocks, and sand—that allowed the structure to "breathe" and survive the test of time. Erik explains the physics of Life Cycle Analysis (LCA), the dangers of modern OSB (particle board), and why "simple" technology often equals low-carbon longevity.
