Garage door cables are the steel lines that work hand-in-hand with your springs to raise and lower the door evenly. They're under constant tension, and when one frays or snaps, the door can hang crooked, jam, or become unsafe to operate. Because cables and springs work as a system, a cable problem is one you want handled promptly and properly.
Bay Best replaces worn and broken cables across the Bay Area, usually the same day. We don't just swap the cable — we check the springs, drums, and balance so the underlying cause is addressed and the door runs smoothly and safely once again.
Broken door? We're on call across the Bay Area, 24/7.
What garage door cables do
Your door has a lift cable on each side, wound around a drum at the top and anchored at the bottom bracket. As the springs wind and unwind, the cables translate that force into the smooth, even lifting of the door. When they're in good shape, you never think about them. When one fails, the imbalance is immediate and obvious.
Signs of a failing or broken cable
Cable problems tend to show up as a door that suddenly moves unevenly. Watch for these signs:
- The door hangs crooked or looks lopsided when moving
- A cable is visibly frayed, rusted, or hanging loose
- The door catches, jerks, or gets stuck on one side
- You can see a cable that has slipped off its drum
- The door drops faster on one side than the other
Door acting up? We can usually help same day.
Why cables fail
Wear, rust, and age
Cables are steel, and steel wears. Years of cycling gradually frays the strands, and moisture — especially in homes near the Bay — can accelerate rust and weaken the cable until it snaps.
Spring and drum problems
Because cables and springs work together, a broken spring or a worn drum often takes a cable with it, or causes a cable to slip off its track. That's why we always inspect the springs and drums when we replace a cable — fixing the cable alone without addressing the cause just invites a repeat.
Why cable repair isn't a DIY job
Like springs, garage door cables are under significant tension, and they're wound around drums that are connected to the spring system. Working on them without releasing that tension safely — and without the right tools — can cause injury or send the door crashing down.
A trained technician can replace both cables, reset the drums, and re-balance the door safely and quickly. It's a repair that's inexpensive when done professionally and risky when it isn't.

What a cable replacement includes
- Inspection of both cables, springs, drums, and bottom brackets
- Replacement of the worn or broken cable — usually both, for balance
- Resetting the drums and re-tensioning the system
- Balancing and safety-testing the door before we leave
- A written warranty on parts and labor
Same-day cable repair across the Bay
A door with a failed cable is unsafe to keep using, so we prioritize these repairs and stock cables on our trucks. In most of the Bay Area we can be out the same day and have your door running balanced and smooth again in a single visit.
If you spot a frayed or snapped cable, stop using the door and give us a call — forcing a door with a bad cable can damage the panels, track, and the second cable.

Cables and springs work as a system
It's a common surprise that a "cable problem" often traces back to the springs, and vice versa. The two work together: the springs provide the counterbalancing force, and the cables transmit it evenly to both sides of the door. When one part of that system fails or falls out of adjustment, it strains the others.
That's why a proper cable repair is never just a cable swap. We inspect the springs, drums, and bottom brackets at the same time, so we fix the actual cause rather than replacing a cable that's destined to fail again in weeks because the underlying problem was never addressed.
What cable repair costs and how long it takes
Replacing both cables typically runs in the low hundreds installed, and the job itself usually takes about an hour, including re-setting the drums, re-tensioning the system, and balancing and testing the door. We quote a firm written price before starting.
Since we carry cables on our trucks, most Bay Area cable repairs are a single same-day visit — you don't lose the use of your garage for days waiting on a part.

Preventing cable failure
Cables fail mostly from age, wear, and rust, and a little attention slows all three. Keeping the cables and the rest of the hardware lightly lubricated reduces friction and helps hold off corrosion, which matters especially for homes near the water. Keeping the door balanced means the cables aren't overworked.
An annual inspection is the best insurance of all: a technician can spot a cable that's beginning to fray and replace it on your schedule, rather than leaving you with a door that fails without warning.
Why we usually replace both cables
When one cable has frayed or snapped, homeowners often ask why we recommend replacing both rather than just the failed one. The answer comes down to balance and timing. Your two lift cables are installed at the same time, carry the same loads, and wear at nearly the same rate — so when one reaches the end of its life, the other is almost always close behind.
Replacing both at once keeps the door balanced and pulling evenly on each side, which is essential for smooth, safe operation and for protecting the springs and opener. It also spares you a second service call and a second unexpected failure just weeks or months later. The small additional cost of the second cable is far less than the cost and hassle of a repeat visit.
As part of the job we also inspect the drums, springs, and bottom brackets, because a cable rarely fails in isolation. Addressing the whole system at once is what turns a cable repair into a lasting fix rather than a patch — and it's how we make sure your door runs true for years, not weeks.
