That bang was the spring — leave the door down — across Miami, Aventura, North Miami Beach, Hallandale Beach, Hollywood, Fort Lauderdale, Boca Raton.
Springs carry the door's entire weight — the opener just steers — and when one lets go it cracks like a gunshot in the garage. From that second the door is several hundred pounds of dead load nobody should lift and no opener should fight. Leave it down and call; spring failures jump our queue across the whole corridor.
We weigh the actual door rather than trusting a chart — hurricane-rated and impact doors run heavier than their looks — then install a matched, coated pair wound to that number. Drums, bearings, and cables get inspected while the shaft is open, because a violent break rarely leaves its neighbors untouched.
Impact-rated doors are the pride of South Florida garages — and the quiet killer of undersized springs. These doors run heavy, and builder-grade springs sized to the minimum burn through their cycle life early, faster still with salt air working the coils. We spec coated, high-cycle pairs matched to the real weight, because down here the door is only as strong as its counterbalance.
