A garage door cycles thousands of times a year. Heat, humidity and salt air in South Florida accelerate everything — rust, dried grease, loose fasteners. This is the same checklist our technicians run on a maintenance visit.
Safety systems
Test these first. If any fail, stop using the door until it's serviced.
- Photo-eye reverse test — wave an object through the beam while closing
- Mechanical reverse test — lay a 2x4 flat on the floor; the door should reverse on contact
- Manual release cord — confirm it disengages and re-engages cleanly
- Wall button and remote lockout function
Balance and movement
A balanced door is the single biggest factor in opener lifespan.
- Balance test — door should hold position at waist height with the opener disengaged
- Listen for grinding, popping or scraping through a full cycle
- Check that the door travels level, not cocked to one side
Hardware and wear parts
Vibration loosens everything over time.
- Tighten hinge, bracket and track bolts (snug, not overtightened)
- Inspect rollers for flat spots, cracks or wobble
- Inspect cables for fraying, rust or slack
- Check the bottom weather seal for cracking and gaps
Lubrication
Use a lithium or silicone-based garage door lubricant — never WD-40, which strips grease. Hit the hinges, rollers, springs and opener rail. Wipe the tracks clean; do not grease them.
- Hinges and roller stems
- Torsion springs (light coat)
- Bearings and end plates
- Opener chain or screw rail
When to hand it off
Anything involving springs, cables, or the bottom brackets is under high tension and belongs to a trained technician. Our UniqueCare protection plan covers this checklist plus priority scheduling if something goes wrong between visits.
The bottom line
Do the safety tests every few months and the full list once a year — or let us handle it on a maintenance visit and get a written report on your door's condition.
