Most emergency calls are a slow-building problem nobody caught. A yearly tune-up finds the fraying cable or the worn roller while it's still a small fix.
Once a year is a reasonable baseline for most homes; more often if the door gets heavy daily use.
Springs, cables, rollers, track alignment, opener force settings, the safety-reversal sensors, and weatherseal condition.
You get a written report on anything worth watching. What you do with it is up to you.
Call for same-day availability, or send the 30-second form and we'll call you back.
