A service call comes in from a family that closed on their Englewood house about a month earlier. The garage door opener worked fine at the walkthrough. Now the spring has snapped, the door won't budge, and the bottom panel has a rust line nobody mentioned. This happens often enough that it's practically a pattern: general home inspectors check that a garage door opens and closes, note it on the report, and move on. They're not garage door technicians, and in a climate with salt air, humidity swings, and storm-force wind loads, that surface-level glance misses a lot.
