Alamo's housing stock centers on 1996, which puts it a few years past the broader service area's 1987-2005 spread but squarely in the same builder-grade window. That means steel sectional doors on torsion springs sized for mid-90s panel weights, not the heavier insulated doors going into new construction now. The openers from that era are mostly chain-drive, half-horsepower units, many on their second or third logic board by now. If your opener still has a yellow learn button that's worn smooth, that's not a coincidence - it's the age of the house talking. We travel out from McAllen for these calls, about 8 miles each way, and the symptoms we see here repeat: dried-out nylon rollers, torsion springs that gave out after 10,000-12,000 cycles, and weatherstrip that's cracked through from sun exposure rather than wear.
