Walled Lake's median year built sits at 1979, which puts most of the neighborhood a solid decade-plus past the 1965 median for our wider service area. That gap matters more than it sounds. A house built in 1979 almost never has the original wood jamb-mounted hardware you still find on the older stock around here - by then, steel sectional doors on galvanized track were standard, and most openers added later were chain-drive units bolted to a header that's held up fine for over 40 years.
There are 3,454 households in Walled Lake, a small slice of the 188,906 households across the whole area we cover out of Novi. That's a tight, identifiable pocket, not a sprawl of mixed-era construction. When we get a call from here, we're not guessing at what decade the garage was framed - the odds are heavily in favor of a late-70s build, and that shapes what we bring on the truck before we even see the door.
