Quick answer
If your door will not lift and you heard a bang, a torsion spring has almost certainly snapped. Do not try to lift the door or use the opener. The springs carry the door's full weight, and a broken one can cause the door to drop. A technician replaces the pair, rebalances the door and resets the opener, usually in a single visit. Book garage door spring repair in Miami.
A broken spring is the garage door problem Miami homeowners call us about most. It is sudden, it is loud, and it often leaves a car trapped inside.
This guide covers how to tell a spring has broken, what not to do, how to get a vehicle out safely, and how to choose the right replacement for Miami conditions.

How to tell a spring is broken
- A gap of a few inches in the torsion spring above the door, where the coil has separated.
- A loud bang from the garage, often when nobody was using the door.
- The opener runs, but the door lifts only a few inches or not at all.
- The door feels extremely heavy when you try to lift it by hand.
- On extension-spring doors, a stretched or hanging spring along one side track.
- Cables hanging loose from the drums at the top corners.
What not to do
Do not keep pressing the opener. It is not designed to lift the full weight of the door, and repeated attempts can strip gears or bend the top section. Do not try to lift the door by hand if it is very heavy, and never put a hand near the spring, the cables or the bottom brackets.
Most importantly, do not attempt to replace or adjust a torsion spring yourself. Winding bars, set screws and stored energy are a dangerous combination, and spring injuries are serious. This is one job where professional replacement is a matter of safety, not just convenience.
Getting your car out
If the door is closed and you must leave, call us first. In many cases our dispatcher can tell you whether it is safe to lift the door with two adults using the emergency release. If it is not safe, our emergency service in Miami can be there the same day, and often within hours.
Why we replace springs in pairs
Most double doors in Miami have two torsion springs installed on the same day. They have made the same number of cycles, so when one breaks, the other is close behind. Replacing only one usually means a second call-out within months and a door that pulls unevenly in the meantime.
We weigh the door and size the springs to that weight, rather than copying the old part number. Doors are often heavier than original after added insulation, reinforcement struts or a replacement section.
Permits and HOA rules in Miami
Miami is in Miami-Dade County, which falls inside Florida's High-Velocity Hurricane Zone (HVHZ). Replacement garage doors here need product approval accepted for HVHZ use — typically a Miami-Dade Notice of Acceptance (NOA) — and a design pressure rating matched to the house. A permit and inspection are normally required, and we take care of both as part of the job.
Most of Miami is not governed by a single HOA, although individual subdivisions, condos and historic districts can have their own rules. If yours does, we provide the specification sheet, product approval and colour details for the application.
Choosing the right spring for Miami
Biscayne Bay sits close to many Miami streets, and bay air carries enough salt to pit spring wire, rust bottom brackets and seize rollers years before the door is otherwise worn out.
For busy households we recommend high-cycle springs rated for around 20,000 to 30,000 cycles. They last two to three times as long as standard springs. For coastal addresses, galvanised or oil-tempered springs with a protective coating resist corrosion much better than bare wire.
What a proper replacement includes
- Matched pair of springs sized to the door weight
- Inspection and, where worn, replacement of cables, drums and bearings
- Rollers, hinges and bottom brackets checked for wear
- Door balance tested so it holds in place halfway up
- Opener force, travel limits and safety reversal reset
- Lubrication of springs, bearings and hinges
If the opener was strained during the failure, we check it too. See opener repair in Miami.
Where we work in Miami
We work across Brickell, Coconut Grove, Little Havana, Coral Way, Upper East Side and Shenandoah, along US-1, I-95 and the Dolphin Expressway, and throughout ZIP codes 33131, 33133, 33135 and 33145. Miami's housing is a dense mix of 1920s–1950s Mediterranean and Art Deco homes, mid-century block houses and new townhouse rows. Narrow lots and alley-access garages mean many Miami doors are single-car and close to the street.
We keep the most common spring sizes on our vans, which is why most Miami spring calls are finished in a single visit.
