That bang was the spring — leave it down, call us — across Oceanway, Northside Jacksonville, Dinsmore, Garden City, New Berlin, Yulee, Callahan.
A torsion spring failing sounds like something hit the house — one sharp crack from the garage, then a door that will not lift. The spring does the actual work of every cycle; without it the opener drags dead weight until it burns out too. Leave the door closed and call: a wound spring stores violent energy, and spring work is where garage-door DIY injuries happen.
We size replacements from the door itself — measured weight, wire gauge, length and diameter — because Northside doors range from light builder panels to heavy insulated and reinforced doors that generic charts get wrong. High-cycle, coated springs, installed and proven balanced before we leave.
River humidity is a spring's patient enemy — moisture settles into the coils every night of the year, pits the steel, and every pit is a future crack. Jacksonville springs rarely die of old age; they die of corrosion fatigue at 6 AM. Coated, high-cycle springs with headroom for the door's true weight are how we put that off for years.
