A 1973 median build year means most of Highland Park's garage doors have been replaced at least once, sometimes twice, since the house went up. What usually hasn't been replaced is the track hardware and the header bracket, which were sized for the lighter single-layer doors common in that era. When a homeowner upgrades to a heavier insulated door without upgrading the spring and the track brackets to match, the new door can sag or the opener can strain - it'll run, but it'll run loud and it'll run short. We check that pairing on every install here, not because it's exotic, but because it's the single most common mismatch on a house this age. It's also worth saying plainly: if the framing itself has shifted out of square, no amount of door or hardware work fixes that, and we'd rather tell you that up front than sell you parts that won't solve the actual problem.
