Garage Door Spring Repair & Replacement in Miami

Look at the torsion spring on the shaft above the door. An intact spring is one continuous coil; a broken one has a gap of two or three inches where the two halves have sprung apart, and the coils either side of the gap are often splayed and shiny where the metal tore. You will usually have heard it go: a broken spring lets go with a bang like a gunshot, and after that the door is far too heavy to lift by hand and the opener strains or will not move it at all. Do not use the door until it is replaced.

A standard torsion spring is wound for about 10,000 cycles, and one cycle is the door going up and coming back down. A household that opens the door four times a day gets roughly seven years out of it; a busy family with the garage as the main entrance gets closer to four. Salt air shortens it further, which is why springs in coastal Miami-Dade and the Keys fail earlier than the same spring inland. High-cycle springs are wound for two to three times the life and cost more up front, and on a door you use constantly they are the cheaper choice over ten years.

From our published Miami cost guide: $409 on a single-car door, and $669 on a double, which runs a matched pair. High-cycle springs cost more up front and last two to three times longer. You get an upfront price before any work starts, and the estimate is free. Every size and spring type is broken down in our spring replacement cost guide. Call (786) 315-9238.

We strongly advise against DIY spring replacement. Garage door springs are under extreme tension and can cause severe injury or death if mishandled. Always hire a licensed professional with proper tools and training.

Yes, we strongly recommend replacing both springs simultaneously. If one spring has broken, the other is likely near the end of its lifespan. Replacing both ensures balanced operation and prevents a second service call.

Yes. Broken springs are replaced the same day across Miami-Dade, Broward and Monroe County, seven days a week from 8am to 6pm, with no weekend rate. Call (786) 315-9238.

Torsion springs mount on a bar above the door and use twisting force to lift. Extension springs mount along the horizontal tracks and stretch to counterbalance weight. Torsion springs are generally safer, longer-lasting, and provide smoother operation.

Springs are matched to the door, never picked off a shelf. The right set comes from the door's weight, its height and the drum size, which means measuring the wire diameter, the inside diameter and the wound length of the old spring before anything is ordered. A spring sized for a lighter door will still lift, but it runs out of cycles years early and leaves the opener straining, which is why a door that ate a spring inside two years usually had the wrong one on it. The wire and inside diameter are measurable at the cone, so read us the numbers on the phone and we will tell you whether they match your door.

Three numbers describe a torsion spring: the wire diameter, the inside diameter of the coil, and the wound length. Wire diameter is the one that matters most and the one people get wrong, so measure across twenty coils and divide by twenty rather than trying to gauge a single wire. The inside diameter is usually stamped on the stationary cone, and the length is measured on the coil itself, not on the shaft. Read those three to us with the door height and we can tell you before we arrive whether what is up there belongs on your door.

No, and of everything on a garage door this is the one where the wrong part is genuinely dangerous. A torsion spring is a calculated component: the wire diameter, the inside diameter, the wound length and the wind direction all follow from your door's weight, its height and the size of the cable drums. Wind direction alone rules out swapping them around, because on a two spring setup the left and right springs are wound opposite ways, and the cones are color coded for it, red for the right hand wind and black for the left. A spring that is close but not right will still lift the door for a while, then run out of cycles years early and leave the opener straining. The two questions above cover how to read the sizing off the spring you already have.
