Most calls fall into a handful of categories, and the age of the house usually tells us which one before we even open the door panel. On the older end of the 1938-2013 range, we're often replacing torsion springs that have simply cycled out, or swapping openers whose circuit boards have finally given up after years of garage heat and cold swings.
In the 1980s and 90s-built homes that make up the bulk of the six named areas here, the common call is worn rollers and misaligned tracks - builder-grade hardware from that era wasn't built for 20-plus years of twice-daily use, and it shows up as grinding, shuddering, or a door that catches halfway up.
Cold-weather calls cluster around broken cables and springs that let go on the first hard freeze of the season, when contracted steel finally fails under tension it was barely holding anyway. We also get regular opener repair and replacement calls, since the electronics age out faster than the mechanical parts around them.
We don't do new home construction installs as a standalone service - our focus is repair and replacement on existing doors, not builder contracts. If that's what you need, we're not the right call.
