What’s Included in a Professional Garage Door Tune-Up (25-Point Checklist)

A garage door tune-up is preventive maintenance that catches problems before they become expensive emergency repairs. During a tune-up, a trained technician inspects, adjusts, and lubricates every component of your garage door system — the door, springs, cables, tracks, rollers, hinges, weatherseals, and opener. The average tune-up costs $179 – $251 and takes 45–90 minutes. Here is exactly what a comprehensive tune-up includes.

The technician disconnects the opener and lifts the door manually to the halfway position (about 4 feet high). A properly balanced door stays in place when released. If it drifts up, the springs have too much tension. If it falls, the springs have too little tension or are weakening. Imbalanced springs strain the opener motor and shorten its life. Adjustment is made by adding or removing quarter-turns from the torsion springs.

Each roller is checked for smooth rotation, bearing wear, and wheel damage. Each hinge is checked for cracks, loose bolts, and excessive play. Worn rollers and hinges are noted for replacement — the technician will inform you of any that need immediate attention versus those that can wait until the next service.

All moving parts receive silicone-based or lithium-based garage door lubricant: every coil of the torsion springs, roller bearings and stems, all hinge pivot points, the torsion spring shaft and bearings, and the opener chain or screw drive (not belt drives). Proper lubrication reduces friction, heat, noise, and wear. In Tucson’s dusty environment, lubrication also prevents abrasive dust from grinding against metal surfaces.

The open and close travel limits are verified and adjusted if the door is not stopping at the correct positions. Force settings are checked to ensure the opener has enough power to close the door smoothly without overriding the safety reverse.
