Cables work under constant tension with the spring system — 5 Star Garage Door Service checks the full assembly, not just the visible fray point.
5 Star Garage Door Service trains San Mateo, CA technicians on this exact service line so you're not the one teaching them on the job.
Every San Mateo, CA technician on this service line carries documentation you can ask to see, and we expect the question.
We check both cables and both drums together, since wear rarely happens in isolation.
We use cables rated to your door's actual weight and spring tension.
Improper cable work while springs are loaded is a real injury risk.
Cables are common stock on our trucks, so most jobs finish in one visit.
Even a few loose strands mean a cable is close to failing under load — replacement cable gets sized to match your spring tension exactly.
A cable that's already snapped usually means the door dropped or hangs crooked — we never operate a door on a snapped cable.
A cable that's slipped off its drum causes uneven hanging — we re-seat it and correct the underlying cause.
Extension spring systems should run safety cables to prevent whip-back — we add these where missing.
The bracket anchoring the cable to the door corrodes over time — this is a less obvious but equally important part of the system.
Call +1-866-597-3069 and give dispatch your San Mateo, CA address and symptoms.
A stocked San Mateo, CA truck heads your way, usually with a same-day arrival window.

"""Second cable was close to going too. Glad they checked both instead of just the one that snapped."""
"""Noticed a few frayed strands and called before it got worse. Tech said it was close to snapping."""
"""Cable snapped and the door dropped crooked. They stabilized it fast and had it fixed same day."""
"""Didn't know safety cables were even a thing until they pointed out mine were missing."""
"""Quick, professional, explained exactly what was worn and why."""
We'll explain the wear pattern we see on your specific cables.
A door suddenly hanging crooked is another common indicator.
Don't attempt to operate the door manually until it's inspected.
Call +1-866-597-3069 rather than attempting this one yourself.
Many older doors were installed without them — we can add them as a standalone upgrade.
