Westminster's housing stock centers on 1970, a few years past the broader service area's 1966 median. That gap matters more than it sounds. By 1970, builders were moving away from the heavier one-piece doors common in the mid-60s tracts and into sectional doors on extension or early torsion springs. If your house here dates from that run, you're more likely to have a torsion spring mounted on a center bracket above the door rather than the side-mounted setup you'd find in an older section nearby. Openers from this era, if original, are long gone, but the track and hardware spacing from a 1970-built door opening can still throw off a modern opener install if nobody checks the header clearance first. We see a mix in Westminster - original hardware on doors that were never replaced, and newer doors bolted onto frames that still carry the original track brackets. Knowing which decade built the house tells us which bracket pattern to expect before we even open the truck.
