2025-01-05 6 min read David Chen
Garage door springs are among the most critical components of your garage door system, yet they're often overlooked until they fail. Understanding how these springs work, recognizing signs of wear, and knowing when to seek professional help can prevent dangerous situations and costly repairs.
Types of Garage Door Springs
Torsion Springs
Torsion springs are mounted horizontally above the garage door opening. They work by twisting and coiling on a shaft when the door moves. These springs are more common in residential applications and are generally safer and longer-lasting than extension springs.
Extension Springs
Extension springs run along the horizontal tracks on both sides of the door. While less expensive than torsion springs, they have a shorter lifespan and can be more dangerous if they break without proper safety cables in place.
How Long Do Garage Door Springs Last?
Most garage door springs are rated for approximately 10,000 cycles. For a typical household, this translates to roughly 7-10 years. Our customers in Smyrna, Milford, and Bridgeton often call us when their springs reach this age range.
Warning Signs Your Springs Need Attention
- The door feels heavy when lifting manually
- The door opens or closes unevenly
- Visible gaps in the spring coils
- Loud bang from the garage
- The door won't stay open
