The mistake we see most in Southworth is someone replacing a frayed cable or a dead sensor themselves and stopping there, when the extension spring on the other side is just as old and just as close to failing. Springs on a matched pair almost always wear out close together. Fixing one side and leaving the other is how you end up with a second service call a few weeks later.
The other place this goes sideways is opener replacement. Southworth's climate sits in the mild band with occasional freeze, so we're not fighting the extreme cold-weather lubricant issues you'd get further inland, but a 1990s-era opener chain drive paired with a newer smart wall control sometimes just doesn't talk to the door correctly. If your opener is original to the house, it may be worth replacing the whole unit rather than bolting a new control panel onto old gearing - we'll tell you honestly when that's the better call instead of billing you for a patch that won't hold.
