How long garage door cables usually last depends on usage, maintenance, cable quality, and environmental conditions, but they generally have a similar lifespan to springs, though they can wear faster if neglected. On average, standard galvanized garage door cables rated for residential use last 8 to 15 years with normal use of 2 to 4 open and close cycles per day. High-quality aircraft-grade stainless steel cables can last 15 to 20 years. Each cycle causes the cable to wind and unwind around the drum or slide through pulleys, which causes gradual fraying and metal fatigue. Factors that shorten lifespan include lack of lubrication on pulleys and drums that causes friction, rust and corrosion from moisture, especially from clogged gutters above the garage that drip water onto the cables and cause rust, and especially if cables rub against sharp track edges or damaged drums. Cables also wear faster if the door is unbalanced due to weak springs, causing uneven tension. Visual signs that cables are near end of life include fraying, kinking, rust spots, or individual strands breaking. Since cables are under high tension and their failure can cause the door to fall, it is recommended to inspect them every six months and replace them when you replace springs, typically every 7 to 12 years, as part of preventive maintenance. Professional inspection costs little and can prevent dangerous failure.
