7 Signs Your Garage Door Spring Is About to Break (Gulf Coast Edition)

The warning signs of a failing garage door spring — and why Mobile's salt air and humidity make them show up sooner than you'd expect.

Garage door springs almost never fail without warning — the warnings are just easy to miss. Here are the seven signs to watch for, plus the reason Mobile homeowners see them earlier than most.

The seven signs

  1. The door feels heavy. Disconnect the opener (red cord) and lift the door by hand. A properly sprung door lifts smoothly and stays at waist height. If it slams down or feels like a workout, the springs are losing tension.
  2. Visible rust or pitting on the coils. Surface rust is where fatigue cracks start. In coastal air, this shows up years before the spring is "old."
  3. A gap in the spring. If you can see a two-inch separation in the coils, the spring has already broken — don't operate the door.
  4. The door opens crooked. One spring carrying more load than the other racks the door in its tracks. Continued use bends tracks and panels.
  5. Loud bang from the garage. The classic. A snapping torsion spring sounds like a gunshot. If you heard it and the door won't lift, you've found your problem.
  6. The opener strains or stops mid-travel. Openers are guides, not lifters. When springs weaken, the opener absorbs the difference — until it can't.
  7. Cables hanging loose. When a spring breaks, cable tension drops and cables jump their drums. Loose cables near the bottom brackets often trace back to a spring failure.

The Gulf Coast twist: springs are rated in cycles (typically 10,000), but that rating assumes a dry environment. Salt-laden humidity pits the steel, and pitting concentrates stress. Around Mobile, standard springs commonly fail at 60–70% of their rated cycle life — a "10-year spring" can be a 6-year spring.

What to do if you spot the signs

Stop using the door and schedule a replacement. Springs under tension are genuinely dangerous to handle — this is firmly professional territory, and the job typically runs $200–$350 for a matched pair, done in about an hour.

Make the next set last longer

Ask about coated or high-cycle springs when you replace. Coated springs resist the corrosion that shortens life here, and high-cycle versions (25,000+) roughly double the interval between replacements. On the Gulf Coast, the upgrade typically pays for itself by skipping one entire replacement cycle. More on spring replacement or call (844) 595-3330.
