Erlanger's median home was built around 1976, which puts it ahead of the broader Florence service area, where the typical house dates closer to 1984. That eight-year gap matters more than it sounds. A house from the mid-70s was framed and finished before a lot of the steel-door, torsion-spring standard setups became default, so you see more variation here: some original wood-panel doors that never got replaced, some retrofits from the 80s and 90s bolted onto openings that weren't built for them, and a fair number of openers added well after the house itself went up. With 7,918 households in Erlanger, that's a real spread of ages and setups, not one uniform type of door. When we come out from Florence, four miles up the road, we're not expecting a single standard job - we're expecting to look at what's actually hanging in the opening before we quote anything.
