Why It Happens Here
A lot of Altadena's housing stock dates to around 1945, and across this whole service area - 45 named communities including Altadena - most of the stock is pre-1960. That matters for rollers specifically: a door installed with the house in 1945 was almost certainly hung with steel rollers on steel stems, no nylon, no sealed bearing, because that's what existed then. Even after an opener retrofit or a panel swap decades later, a lot of these doors kept their original roller stems and track brackets, because rollers are the part nobody thinks to check until one snaps or a bearing seizes. Steel-on-steel rollers wear the track itself over the decades, so by the time a roller finally fails here, the track it's been riding in has often worn an hourglass groove that a straight roller swap won't fix on its own - we usually find we're correcting track wear at the same visit.
Parts We Carry
For a door of this vintage we carry sealed 10-ball and 7-ball nylon rollers in the stem lengths that fit the older narrow track still common on Altadena's 1940s-era garages, plus the longer stems some retrofit conversions need. We stock standard 2-inch and 3-inch roller wheel sizes on the truck. What we don't carry as a standing stock item is oversized commercial-door roller hardware - if a detached garage or converted carriage house out there runs an oversized or custom track, that part gets special-ordered and the job becomes a two-visit repair, first to confirm the size, second to install. We'd rather tell you that up front than quote a same-visit fix we can't deliver.
