What should a professional garage door maintenance visit include?

A complete visit should inspect the spring system, cables, drums, rollers, hinges, tracks, fasteners, opener travel and force, safety sensors, door balance, and overall operation before documenting any recommended repair.

Systems covered in the video

Spring, cable, drum, bearing, roller, and hinge condition.
Track alignment, fastener security, and door balance.
Opener force, travel limits, and safety-reversal operation.
Photo-eye alignment, lubrication points, and final cycle testing.

Safety note: Visual checks and cleaning are homeowner-safe. Spring, cable, drum, bottom-bracket, and opener-force adjustments should be handled by a trained garage door technician.
