Mission Bend has about 10,915 households, a small slice of the 86,692 across our whole service area, but it's a concentrated slice: most of those houses went up around the same years, so the doors fail in the same handful of ways. We keep torsion springs sized for the standard 7-foot and 8-foot sectional doors that went in during the mid-1980s build-out, along with the rollers and end bearings that match that era's track width. What we don't carry on the truck is anything for a door that's been heavily customized or swapped out for a newer low-headroom system - those parts get ordered, and that can mean a short wait depending on what the manufacturer has in stock. If your opener is original to the house, the circuit board is one more thing worth checking before we assume the motor's the problem.
