Across the wider service area the housing stock runs from 1975 to 2009, with the middle of that range landing around 1984. Rainbow sits on the older edge of that curve, with a median build year around 1976. That eight-year gap matters more than it sounds like it should, because garage door hardware changed a lot between the mid-70s and the mid-80s - extension springs mounted on horizontal tracks were still common in the earlier builds, and a fair number of those doors in Rainbow are still running on the original setup, sometimes with parts that have never been swapped out.
The area's mild temperate climate hasn't stressed those doors the way a freeze-thaw region would, so a lot of them have limped along on original hardware far longer than they would somewhere with real winters. That's not always good news - it means when something finally gives, it's often the whole assembly at once, not one worn part. With around 599 households in Rainbow on older stock like this, we see more full spring-and-cable jobs out here than we do simple panel dents.
