The service area overall has commercial and residential stock running from 1976 to 2014, with a lot of it clustering in the 1980s and 90s. Midlothian doesn't follow that pattern. Its own median build year sits closer to 2006, a decade newer than the area's overall median, and that decade matters for commercial doors specifically. A lot of Midlothian's commercial construction happened during a single growth push, which means a lot of buildings went up with whatever door and opener spec was standard at the time - often a residential-grade or light-commercial jackshaft opener paired with a door that sees genuinely commercial cycle counts.
That mismatch is the fault we see most here: not rust, not rot, not a door that's outlived its hardware, but an opener that was undersized for the traffic from day one and is now a decade or more into wear it was never built to handle. Household income in Midlothian runs well above the wider service area's $79,739 median, and that tends to mean businesses here spec heavier doors on renovation rather than patch the original setup, which is usually the right call once you're past year ten.
