Bell Gardens sits about 14 miles from our Pasadena shop, and the housing stock here runs older and more uniform than a lot of the towns closer to us. The median build year across the wider service area is 1959, and Bell Gardens tracks right at that number instead of the newer pockets you find near Arcadia or Duarte. That means a tight run of postwar tract homes, mostly single-car and two-car attached garages, put up before steel roll-up doors with factory torsion systems became the standard install. With 9,748 households in the area, you're looking at a lot of original garage openings that have been through one or two door replacements since, but the framing and header heights often stayed put from the original build. That matters because a lot of newer door lines assume header clearance and track depth that these older openings don't have, so a straight swap-in job sometimes needs bracket or jamb work nobody quoted for.
