What's Really Killing New Houses (And Why the Old Ones Won't Die)

A wall that has kept the rain out for two hundred years — and a fifteen-year-old wall two streets over already black with mold. Same climate, same rain. The difference isn't nostalgia. It's moisture, and a handful of things the old builders got right that the modern industry quietly designed out. In this video we take apart how houses actually fail: plaster vs drywall, wood windows vs vinyl, old-growth framing, deep eaves, foundations, spray foam, and lime mortar — and the "energy upgrades" that turn a bone-dry 100-year-old house into wet sawdust in a few years. ⏱️ CHAPTERS 0:00 The paradox: why one wall lasts and one rots 1:14 The real secret is water — the 4 jobs every survivor does 2:07 Plaster vs drywall (and the tap test) 4:58 Wood windows vs vinyl: repair vs replace 7:07 The bones: old-growth wood & what makes it last 9:07 The roof & eaves: the house's umbrella 11:26 Water, foundations & the honest slab 14:41 The autopsy: the upgrade that kills old houses 18:31 Your house — tell me below 💬 TELL US ABOUT YOUR HOUSE Drop a comment in this exact format: year · state or region · the one original feature that still works.
