What a Garage Door Tune-Up Actually Checks (The Full List)

The balance test comes first

Disconnect the opener (door down) and lift the door by hand to halfway. A balanced door stays where you leave it. One that drops has springs losing tension; one that flies up has too much. Balance is the root measurement on the whole system: an out-of-balance door makes the opener strain on every cycle, wears cables unevenly, and is how 'opener problems' are born.

Springs and cables — the safety-critical pair

• Spring tension and condition — rust, stretched coils, and the gap-check on torsion springs.
• Lift cables, inspected inch by inch for fraying, especially at the bottom brackets where water sits.
• Cable drums and end bearings for wear and wobble.

These parts are under high tension and are adjusted or replaced by the technician only — they're on this list so you know what you're paying to have examined, not as a DIY invitation.

The rolling hardware

• Rollers — nylon vs. worn steel, cracked wheels, seized bearings (the source of most 'my door is so loud' calls).
• Hinges for cracks and loose fasteners.
• Tracks for alignment, dents and loose wall brackets.
• All fasteners on the door and track hardware, tightened.

The opener and its safety systems

• Force and travel limit settings — a door that presses too hard at the floor is a hazard and a seal-killer.
• The safety reverse test with a 2x4 laid flat in the door's path.
• Photo-eye sensor alignment and a lens clean.
• Drive chain or belt tension, and remote/keypad function.

Seals and lubrication

Bottom seal and perimeter weatherstripping checked for cracks and gaps — in the mountains this is a freeze-protection item, not a cosmetic one. Then the moving parts get the right lubricant: silicone or lithium garage-door lubricant on hinges, rollers and springs.

What you get at the end

A plain report: what's fine, what's wearing and worth watching, and anything that genuinely needs work — shown to you at the door, not sold to you. Most doors need nothing beyond the tune-up itself. Book yours on the tune-up page or call (828) 575-4543 — Daniela, our AI receptionist, answers 24/7.
