A house built around 1987 - which is the median year for this area - usually has galvanized torsion springs on a single center bracket and an opener that's been swapped out once or twice since the house was built. By now most of the original chain-drive units have failed or been replaced, but the track and header hardware from the original build are often still in place, and that hardware wasn't sized for the heavier insulated doors a lot of owners want today. When we get a call to add a heavier door to an older track and bracket, sometimes the header reinforcement needs work too, not just the door. We'll tell you straight if that's the case rather than hanging a door on hardware that won't hold it. On the other end, a few homes here are newer builds with higher-cycle springs and smart openers already installed, where the issue is almost always a sensor or wiring fault rather than anything mechanical.
