The honest limitation: if your door and opener are both original to a house built in the 1980s or 90s, replacing just the failed part sometimes isn't worth it. A new opener logic board won't help much if the rail is bent, and a new spring on badly worn rollers just transfers the strain somewhere else. We'll say so rather than sell you a spring job that fails again in six months. The other complication is access - if you're out past Fresno or Sienna, eleven miles from the core of Sugar Land, or down toward Rosharon at twenty, scheduling runs on a route, not a first-call basis, so same-day isn't guaranteed the farther out you are. Closer in, around Telfair or New Territory, we're usually there faster simply because of the drive.
