## Resource

As tornado season ramps up, we separate myth from fact about storm protection and explain what actually makes a shelter tornado-rated. Then bestselling author Tracy Sierra takes us inside her 300-year-old New England colonial, where squeaky floorboards, carved windowpanes, and a real bump in the night helped spark her latest novel. Finally, structural engineer Dr. Nehemiah Mabry lays out the clear line between cosmetic updates and risky renovations, including the warning signs that mean it’s time to call in a licensed pro. On this episode you’ll learn: * Whether insulating between an 1806 home’s basement and original first-floor wood floors is worth it, and how to do it without trapping moisture. * Why certain rooms and interior walls can feel unusually hot in winter and cold in summer with a ducted heat-pump system, and how to diagnose air leakage or airflow patterns. * What to do when a single slate shower tile starts turning to powder, including whether it’s a bad tile, a moisture issue, and how sealing and maintenance can help. * Options for updating a large vaulted popcorn ceiling in a 1992 home. All of this, plus we’re answering your home improvement questions at 877-This Old House Radio Hour! — That’s (877) 864-7460.
