Frayed or snapped cables replaced before they let go — across Pinecrest, Palmetto Bay, Coral Gables, South Miami, Kendall, Cutler Bay, Coconut Grove.
The two steel cables running up the sides of your door are what actually carry it, translating spring torque into a controlled lift. When one frays or jumps its drum the door instantly goes crooked, jams in the tracks, or slams down on one side — and because the cables work under the same stored tension as the springs, this is another repair that should never be a weekend project.
In South Miami-Dade, cable failure is almost always a corrosion story. Moist, salt-tinged air works into the strands, the strands rust from the inside out, and one morning a cable that looked merely 'a little fuzzy' lets go. We replace cables in matched pairs with the correct length and gauge, inspect the drums and bottom brackets they wind onto, and reset the door true in its tracks.
Cables fail here from the inside out: humidity and bay salt seep between the wound steel strands, so the visible outside can look fine while the core rusts thin. That's why we treat frayed strands or rust bloom as replace-now, not watch-it — and why every cable we install is a corrosion-resistant type suited to the eastern edge of the county, where the salt air is strongest.
The door is clamped and spring tension safely managed before any cable is touched — this is the step DIY skips, and it's the dangerous one.
One clear price for cables, and for any drum or bracket the inspection shows is worn, approved before work begins.
Both cables are replaced together at the correct length and gauge, wound evenly onto inspected drums.
We level the door in the opening, verify even travel and spring balance, and cycle it until it runs straight and quiet.
