Housing in this service area spans 1956 to 2014, with the median home dating to 1983, and that spread matters more than people think when it comes to garage doors. A house from the late 50s or 60s may still have its original one-piece door on hardware nobody manufactures anymore, while a home from the 80s or 90s typically has a sectional steel door on extension springs, the standard builder-grade setup from that era.
Anything built in the 2000s or later is more likely to have torsion springs and an opener with rolling-code security, which is a different repair altogether. That mix is why no single part fits every job, and why we ask the age of the house before we load the truck.
