This area sits in a severe-heat climate band, and heat is hard on the plastic and nylon components that 2000s-era builder-grade doors leaned on to keep costs down. Daily thermal expansion and contraction on a steel track, paired with a lighter-gauge spring than you'd find on an older, heavier door, means the failure point in St. Johns tends to be the spring or the roller rather than the panel itself. Combine that with a median household income under the area average, and you get a pattern we see a lot here: owners wait longer to call because the repair has to compete with other bills, and by the time we're out, a simple spring job has become a spring-and-track job because the door kept running on a cable half off the drum. Calling at the first grinding noise, rather than the dead stop, is the single thing that keeps this cheap.
