The median build year in Four Corners runs around 2004, noticeably later than the 1990 median across the broader area this company serves. Most of the service area's roughly 12,994 owner-occupied houses trace back to the 1980s and 90s stock, but Four Corners sits apart from that pattern as a later-phase development. Median household income here runs about $72,853, below the $95,273 median for the wider service area, which tends to line up with more production-grade openers and standard steel doors rather than the higher-end insulated or custom panel doors you see in some of the older, wealthier pockets nearby. Builders in the early 2000s largely standardized on chain-drive or belt-drive openers with basic safety sensor kits, and torsion spring setups sized to a specific door weight at the time of install. If a door has been upgraded since - heavier insulated panels, added insulation kits - the original spring sizing may no longer match, which is a common source of hard-to-diagnose lift problems in homes this age.
