Once a year is the standard, especially with temperature swings, dust, or coastal salt air. The garage door is the largest moving part on most homes and cycles 1,500+ times a year — an annual tune-up extends spring life, catches problems early, and keeps a new-install warranty valid.

No. A broken torsion spring removes the counterweight, so the door becomes its full 150 to 200 pounds of dead weight on the cables and opener. Lifting manually is how people hurt their back, snap the other cable, or drop a panel. Leave the door where it is and call us — same-day dispatch is the norm.

Don't force it open. If the spring or cable failed, forcing it can drop the door. If the spring is intact and only the opener is broken, the red emergency-release cord lets you lift the door manually; if the spring is broken, do not pull the release. Call us — car-trapped-inside is a true emergency and we dispatch within hours.

Yes. Photo-eye reverse-on-obstruction sensors are federally required on every residential garage door made since 1993 — they make the door reverse if a person, pet, or object breaks the beam. A door that closes without reversing is genuinely dangerous around kids and pets. Same-day fix available.
