Most houses here went up between 1976 and 2012, with the median sitting around 1993, which means a lot of original garage doors and openers are now thirty-plus years old. That's not a guess about one street - it's the pattern across the twelve named areas that make up this service territory, from the growth near Redstone Arsenal six miles out to the newer pockets toward Priceville fourteen miles away. Madison sits close enough to Redstone Arsenal, eight miles from Triana, and ten miles from Harvest that the housing waves across those twelve named areas followed the same builder-grade door specs. Builders in that era mostly used the same handful of door and opener lines, sized for the code and climate expectations of the time, not for today's insulation standards or today's opener electronics. With 12,629 owner-occupied houses out of 15,816 households in the service area, most of this installation work is replacing an original door, not adding a first one. When we get a call for installation rather than a quick repair, it's almost always because the door itself - panels, hinges, track gauge - has aged out, not because one part failed in isolation.
