Understanding the Culprits: What Causes Garage Door Cables to Break?


Garage doors are an essential part of our daily lives, providing convenience and security. However, like any mechanical system, they are subject to wear and tear over time. One common issue that homeowners face is the breaking of garage door cables. In this blog, we’ll delve into the factors that contribute to garage door cable breakage, helping you understand the causes and take preventive measures.

**1. Age and Wear:

One of the primary reasons for garage door cable breakage is simply the passage of time. As your garage door system ages, its components, including cables, undergo stress and strain from frequent use. Over time, this wear weakens the cables, making them susceptible to breaking. Regular maintenance and inspections can help catch signs of wear early and extend the lifespan of your cables.

**2. Incorrect Installation:

Improper installation can significantly impact the durability of your garage door cables. If the cables are not correctly aligned or tensioned during installation, they can experience uneven stress, leading to premature wear and eventual breakage. Hiring a professional for installation ensures proper setup and reduces the risk of cable failure.

**3. Rust and Corrosion:

Exposure to moisture, humidity, and other environmental elements can lead to rust and corrosion on the garage door cables. Rust weakens the structural integrity of the cables, making them more prone to snapping under pressure. Regularly inspect your cables for signs of rust and consider applying a rust-resistant coating to protect them.

**4. Excessive Weight:

Garage doors are heavy, and the cables play a crucial role in supporting their weight. If your garage door is not properly balanced or if the springs are worn out, it can put undue stress on the cables. Over time, this can lead to cable breakage. Ensure that your garage door is balanced and that the springs are in good condition to prevent unnecessary strain on the cables.

**5. Lack of Maintenance:

Neglecting regular maintenance can contribute to garage door cable breakage. Dust, debris, and dirt can accumulate on the cables, causing friction and wear. Additionally, lack of lubrication can lead to increased friction, causing the cables to weaken and break. Regularly clean and lubricate your garage door cables as part of your maintenance routine.


Understanding the causes of garage door cable breakage empowers homeowners to take proactive steps to prevent this common issue. Regular maintenance, proper installation, and addressing issues promptly can significantly extend the lifespan of your garage door cables. If you notice any signs of wear, rust, or imbalance, it’s advisable to consult a professional garage door technician to assess and address the problem before it escalates. By investing in proper care and maintenance, you can enjoy a smoothly functioning garage door system for years to come.
