We don't quote a flat number for South Amboy because the age of the stock here pushes the job in a specific direction: more openings need a non-standard size or a header modification than in newer parts of the territory. Both of those add labor and sometimes a special-order door, which takes longer to arrive than a stock size.
What we can say is that the household income here, $110,125, runs below the $122,610 median across the wider service area, and that's part of why we lead with mid-tier insulated steel doors on these jobs rather than starting the conversation at premium wood-composite. It's not a ceiling on what we'll sell you, it's just where the first quote usually lands.
The climate here calls for a door rated for the region's cold, severe-winter conditions regardless of the house's age, so insulation value isn't a place to cut corners to save on the install. Where we do trim cost is on hardware upgrades that don't matter for a garage that isn't heated or finished on the inside.
