Walls sits on the newer end of the housing stock we work on. The typical house here went up around 1998, which puts it past the original one-piece and side-mount torsion era that defines a lot of the older pockets in this service area. By the time most Walls garages were framed, builders had already shifted to extension or center-mount torsion springs on steel sectional doors, and the openers from that period are more likely to be chain-drive units with a logic board instead of the old relay-and-capacitor type. That matters when a part fails: we're not hunting for an obsolete bracket, we're usually dealing with wear - worn rollers, a stretched cable, a spring that's simply lived out its cycle count. One thing we won't do is force a 1998-era torsion assembly to accept a replacement spring sized for a 1970s door. If the hardware doesn't match, we tell you before we quote the job, not after.
