Dickinson sits about 4 miles from our shop in League City, and the housing here clusters tight around 1984 as a median build year. That's a narrower band than the wider service area, which stretches from houses built in 1956 up through new construction in 2014. A neighborhood that went up mostly in one decade tends to have doors and openers that fail in waves, not one at a time, because the same builder used the same hardware on street after street. When one torsion spring on an '84 build starts rusting through, the identical spring two doors down usually isn't far behind. That's different from a street with houses spanning sixty years, where failures are scattered and random. In Dickinson, when we get one call, we're not surprised to get three more from the same block within a season.
