Narrow hardware failure family
Camano doesn't give you that spread. The homes out here cluster tight around 1991, so when a door locks up, slams down crooked, or the opener grinds and quits, it's almost always the same family of hardware giving out: torsion springs on steel sectional doors, galvanized track that's had thirty-plus winters on it, and openers that are on their second or third motor by now.
