By the way, I was a loyal This Old House watcher back in the early days when Bob Vila hosted the show. He was always so knowledgeable and authoritative. Often, he had to deliver bad news to startled and sometimes irritated homeowners who had no idea they needed new furnaces or wiring or rotted wood removed. Just what did they think was going on behind those moldy walls? Bob always kept everyone in line, even when the going got tough and the job went way over budget.
