Annual Garage Door Service
Purpose
Define a standard annual service for residential garage doors and openers. The door is the largest moving object in most homes; a failing torsion spring or worn safety system is a personal-injury risk. A 45-minute annual visit catches the wear before it becomes the failure.
Scope
Applies to:
- Single-car residential sectional doors with torsion or extension springs
- Double-car residential sectional doors with torsion springs
- Residential door openers (chain, belt, screw drive)
Excludes commercial / industrial doors, rolling steel doors, and any door with broken springs requiring immediate repair (separate emergency-service SOP).
Responsibilities
- Dispatcher confirms door size + opener brand at booking
- Lead technician runs the protocol + customer briefing
- Customer witnesses the safety-reverse test and signs off
Procedure
- Customer briefing. "I'll be testing the safety systems, inspecting the springs and cables, and lubricating everything. About 45 minutes."
- Visual inspection - door panels. Dents, cracks, rust-through, water damage. Photograph any structural damage.
- Inspect torsion spring(s). Look for gaps in the coil (springs lose tension over their cycle life - typical residential rated 10,000 - 25,000 cycles). Measure the gap between coils with a tape; growing gap = spring fatiguing.
- Inspect cables. Look for fraying, kinks, or rust. ANY visible fraying = replace immediately - a cable failure under tension is a serious injury risk.
- Inspect rollers. Worn nylon, flat spots, missing bearings = replace. Steel rollers also wear; check for play in the stem.
- Inspect hinges. Cracks in the metal, elongated bolt holes, loose fasteners.
- Check the bottom seal (astragal). Cracked or compressed flat = replace; it's the home's pest + draft barrier.
- Lubricate. Spring coils (light coat of garage-door lube - NOT WD-40, that's a solvent), hinges, roller bearings (if metal), opener chain or screw drive per manufacturer.
- Test the safety reverse. With the door fully closed, place a 2x4 flat on the floor under the door. Open the opener, then close. The door MUST reverse on contact. If it doesn't, the down-force is set too high - adjust per manufacturer or replace the opener if non-adjustable.
- Test the photo eyes. Wave a hand through the beam during a close cycle. Door must reverse instantly. Misaligned eyes are a common silent failure.
- Operate the door 5 cycles. Listen for grinding, squealing, or hesitation in any specific position. Note where it occurs; usually indicates roller or hinge wear at that travel point.
- Document with photos. Springs, cables, rollers, opener label.
Acceptance Criteria
- No frayed cables
- No visible coil-gap growth on springs (compare year-over-year)
- Safety reverse passes the 2x4 test
- Photo eyes interrupt-tested and operational
- Door cycles smoothly through 5 complete operations
- Customer signs field report acknowledging tests + any flagged repair quotes
Torsion springs are under thousands of pounds of force. NEVER adjust, remove, or wind a torsion spring without the proper winding bars + training. A spring that releases unexpectedly has crushed hands, broken arms, and killed techs. If a spring needs replacement, do it; if you're not trained, refer it.
