Your garage door spring is one of the hardest-working components in your home. It bears the full weight of your door every time it opens and closes — sometimes 3–5 times a day. Standard springs are rated for about 10,000 cycles, which translates to roughly 7–10 years of normal use.

The problem is that most homeowners don't notice a spring is failing until it breaks completely — leaving them stuck inside or outside their garage. Knowing the warning signs can save you from that frustrating situation.

7 Warning Signs Your Spring Is Failing

The Door Feels Heavier Than Usual

If your door suddenly feels much heavier when you lift it manually, the spring tension has likely decreased. A properly balanced door should feel nearly weightless when lifted by hand.

The Door Opens Unevenly or Crooked

If one side of the door rises faster than the other, or the door looks tilted when open, one spring may be weaker than the other. This is common with two-spring systems.

You Hear a Loud Bang from the Garage

A broken torsion spring makes a loud bang — like a firecracker going off in your garage. If you hear this and your door won't open, the spring has snapped.

There's a Gap in the Spring

Look at the torsion spring above your door. If you see a gap of 2–3 inches in the coil, the spring has broken and needs immediate replacement.

The Opener Strains or Reverses

If your opener struggles to lift the door, moves slowly, or reverses before fully opening, it may be working against a failing spring. Continued use can burn out the opener motor.

Visible Rust or Wear on the Coils

Rust weakens the metal and accelerates failure. If you see significant rust or the coils look stretched and uneven, the spring is near the end of its life.

The Door Won't Stay Open

A properly tensioned door should stay open at waist height when released. If it falls back down, the spring tension is insufficient and replacement is needed.

What to Do If Your Spring Breaks

Stop using the door immediately. A door with a broken spring can fall unexpectedly and cause serious injury. Do not attempt to operate it with the opener — this can damage the opener motor and worsen the situation.

Call a licensed garage door professional for same-day service. Spring replacement at Exito Garage Doors ranges from $300–$550 for residential doors, including parts and labor. We recommend replacing both springs at the same time — if one has failed, the other is likely close behind.

How to Extend Spring Life

Annual lubrication with a silicone-based spray (never WD-40) keeps the coils from rusting and reduces friction. A professional tune-up once a year can catch tension issues before they become failures. Consider upgrading to high-cycle springs (rated for 25,000–50,000 cycles) for significantly longer life.
