Across the area we serve - more than 238,000 households, with roughly 114,000 of those in owner-occupied houses - the stock is overwhelmingly 1960s and 70s construction, spread across 48 named neighborhoods and communities rather than concentrated in one build era.
That's a long run of houses with garages built to a similar depth and door width, which is part of why we can often predict the hardware before we open the panel. Most of what we work on went up between 1957 and 1975, with the broader service area stretching out to homes built as late as 2005.
Nearby communities like Golden Triangle, just a few miles to the southwest, and Southwest Minneapolis to the east share a lot of that same build window, so the torsion spring sizes, track gauges, and panel styles we carry on the truck cover a wide swath of what's actually installed in driveways around here.
Newer construction closer to the 2005 end of that range tends to have insulated doors and belt-drive openers already, which changes what commonly fails - less spring fatigue, more sensor and circuit board issues.
