New Underwood's homes carry a median build year of 1972, noticeably older than the 1989 median across the rest of our coverage area. With only about 160 households in town, this isn't a subdivision that got built out in one wave of 1990s construction like a lot of the Rapid City suburbs. It's an older base of houses, which means older garages and older doors that were never swapped out when newer hardware became standard.
A door installed in the early-to-mid 1970s was built for a different set of expectations than anything going up today. Steel gauges were thinner in places, insulation wasn't assumed, and the track and spring systems that shipped standard back then are not what a supply house hands you now when you walk in for a replacement part. That gap matters more here than in newer parts of our area, because a bigger share of New Underwood's garages are still running close to original equipment.
Median household income here runs $54,167, lower than other parts of our coverage area. That's not a knock on the town - it just means a lot of owners are making a call between patching an old system and replacing it outright, and we try to be straight with people about which makes sense for their specific door rather than defaulting to the more expensive answer.
