Broken Spring: Repair Options & Costs

A broken garage door spring is one of the most common reasons a door stops opening. The only safe repair option is professional replacement of the broken spring, and often its mate on the other side. Attempting to adjust or remove springs without proper tools and training can cause serious injury.

Why a Broken Spring Stops the Door

Garage doors are heavy. A single-car door often weighs 150 pounds or more, while a double-car door can exceed 300 pounds. Springs counterbalance that weight so the opener and the person lifting the door do not have to carry the full load.

When a spring breaks, that counterbalance vanishes. The door may feel impossibly heavy, refuse to stay open, or slam shut. The opener may strain or trip its safety sensor because it detects more resistance than it was designed to handle.

Torsion springs mount above the door and twist to store energy. Extension springs run along the sides and stretch. Both operate under extreme tension. A standard torsion spring on a 16-foot by 7-foot door might be rated to lift roughly 250 pounds. If that spring snaps while you are standing beneath it, the released force can cause severe injury or death.

Repair Option 1: Professional Spring Replacement

Replacing a broken spring is the standard repair. A technician releases the remaining tension, removes the broken spring, installs a new one matched to the door weight, and rebalances the system.

Cost estimates for torsion spring replacement run from $150 to $400. That range covers parts and labor for most residential doors. If your door uses two springs and only one has broken, many technicians recommend replacing both at once. The arithmetic is straightforward: one spring at $200 plus labor might total $300, while doing both springs in the same visit might cost $400 to $500 total rather than paying for two separate service calls later.

Extension spring replacement tends to sit at the lower end of that range, though prices vary by region and door size. These figures are estimates, not guaranteed quotes.

Repair Option 2: Cable Repair or Replacement

Springs and cables work together. When a spring breaks, the cable can fray, slip off the drum, or snap under the sudden shift in load. If you see a loose or damaged cable, it needs attention before the door operates safely.

Cable repair typically costs between $150 and $350. A technician will inspect the cable, drum, and bottom brackets, then replace worn parts and re-tension the system. Because cables are under tension when the door is assembled, this is not a DIY task.

If both the spring and cable need work, the combined visit might cost roughly $300 to $600, depending on parts and labor. That is still far less than replacing the entire door.

Repair Option 3: Full Door Replacement

Sometimes a broken spring reveals bigger problems. If the door panels are dented, warped, or rotted, or if the opener is nearing the end of its life, replacing the whole door may make more sense than repeated repairs.

A new door installed costs between $800 and $4,000, depending on material, size, insulation, and style. Panel replacement alone runs $200 to $600 per panel, which can add up quickly on a multi-panel door. Opener installation adds another $300 to $800 if the existing unit is also failing.

Before choosing a full replacement, have a technician inspect the tracks, hinges, rollers, and frame. If those components are sound, spring repair is usually the more economical path.

Emergency Service vs. Scheduled Repair

A broken spring often happens at an inconvenient time. If the door is stuck open or closed and you need immediate access, emergency call-out service typically costs $250 to $500 on top of the repair price.

Scheduled repair during normal business hours avoids that premium. If the door is stuck closed and you can park elsewhere for a day, waiting for a standard appointment can save a few hundred dollars. If the door is stuck open overnight, securing the garage and waiting until morning is often safer than forcing it.

DIY Is Not a Safe Option

Some homeowners consider replacing springs themselves to save money. This is one repair where the savings are not worth the risk. Torsion springs can store enough force to lift hundreds of pounds. Winding bars can slip, set screws can back out, and a snapped spring can strike with lethal force.

Extension springs are slightly less dangerous to approach, but they still operate under tension and can cause injury if removed improperly. Safety cables should be present on extension spring systems to contain a break, but installing or adjusting them still requires knowledge of door balance and hardware.

What to Expect During a Service Visit

A technician will typically:

1. Disconnect the opener and secure the door in place.
2. Release any remaining spring tension using winding bars or proper release tools.
3. Remove the broken spring and inspect the shaft, bearings, drums, and cables.
4. Install a new spring matched to the door’s weight and height.
5. Rebalance the door by hand to confirm it stays put when lifted halfway.
6. Reconnect the opener and test open and close cycles.

The visit usually takes one to two hours for a straightforward spring replacement. If cables or other hardware need replacement, it may take longer.

Preventing the Next Break

Springs wear out over time. Most residential torsion springs are rated for around 10,000 cycles. One cycle is one open and one close. A household that uses the door four times a day might reach that limit in about seven years.

Routine maintenance can help you spot wear before a sudden break. Listen for squeaking or grinding, watch for gaps in the spring coils, and check that the door stays balanced when lifted halfway. If the door drifts up or down on its own, the springs may be losing tension.

Lubricating springs and checking hardware annually is part of a sound maintenance plan. Our guide to garage door repair maintenance covers seasonal checks that can extend the life of springs, rollers, and tracks.

Bottom Line

A broken spring means the door is unsafe to operate until it is replaced. Professional torsion spring replacement costs an estimated $150 to $400, while cable repair runs $150 to $350. Emergency service adds $250 to $500 if you need same-day help. Full door replacement starts around $800 and can reach $4,000, so spring repair is almost always the first step unless the door itself is failing.

Never attempt to remove or adjust springs yourself. Call a qualified technician, have both springs evaluated, and address any cable damage at the same visit. That approach keeps your garage safe and avoids a more expensive repair later.
