If you're calling about a new install rather than a repair, it's usually one of two things in a house this age: the original builder-grade door has reached the end of its panel life around the twenty-year mark, or the opener has failed in a way that's not worth matching to an aging door. With a median build year of 2001, a lot of Holts Summit garages are right in that window now.
What you're less likely to be dealing with, compared to houses on the older end of the service area's 1938-2003 range, is bent track from a door that was never sized right in the first place, or torsion hardware so old that replacement parts have to be special-ordered. Newer construction here means the opening itself is usually fine - it's the door and opener that have worn out, not the structure around them.
We'll tell you straight if a repair makes more sense than a full replacement. A worn roller or a failed sensor on an otherwise sound five-year-old door doesn't need a new door. If what you've got is a twenty-plus-year-old steel door with a dead opener and a failing spring, that's a different conversation.
