Broken Garage Door Spring Repair

Why springs break, and why it is not your fault

A garage door is heavy. A typical two-car steel door weighs somewhere between 150 and 250 pounds, and a wood or insulated carriage-style door can weigh much more. The opener does not lift that weight. The springs do. They are wound to hold almost the entire weight of the door, so the opener only has to nudge it along.

Every time the door opens and closes, the spring steel flexes. A standard torsion spring is commonly rated for around 10,000 cycles, which is roughly seven to ten years for a household that uses the garage as its front door. After that the steel fatigues and eventually cracks, usually without warning. Cold snaps make it worse: steel is less forgiving at low temperatures, which is why technicians on Long Island and upstate see a jump in broken springs during the first hard freeze of winter.

Torsion springs and extension springs

Torsion springs (most homes built or updated since the 1990s)

Torsion springs sit on a steel shaft above the door opening. When one breaks you can usually see a two-inch gap in the coil. Most double doors have two torsion springs, and many single doors have one. When one of a pair breaks, technicians usually recommend replacing both, because the other spring has done the same number of cycles and is close behind.

Extension springs (older and lighter doors)

Extension springs run along the horizontal tracks on each side of the door and stretch as the door closes. When they break they can whip across the garage, so they should always have a safety cable running through the middle. If yours do not, ask the technician to add containment cables while they are there.

Other spring systems you may find

Not every door uses a bare torsion spring on an open shaft. Some brands enclose the springs inside a steel tube above the door, wound from one end with a special tool or a drill fitting. Others use a single spring that runs the full width of the door. These systems look tidy, but they take brand-specific parts, and not every technician carries them on the truck. If your springs are hidden inside a tube, mention it when you call, and a photo of the label on the end bracket helps the company bring the right parts.

Very old or very light doors, including some one-piece tilt-up doors on older detached garages, use large extension springs on pivoting arms at each side of the opening. Parts for those can be harder to find, and a broken one is often the moment people decide to replace the whole door with a modern sectional one.

Signs a spring is close to breaking

Springs rarely give much warning, but there are a few signs worth watching for, especially in the fall before the first freeze:

• The door no longer stays put when you stop it halfway by hand, and drifts down or creeps up
• One side of the door rises before the other, or the door looks slightly crooked as it moves
• Rust on the coils, or coils that look stretched or uneven next to each other
• The opener sounds like it is working harder than it used to, or the door closes with a thump
• The springs have been on the door for eight years or more and the garage is used every day

None of these means the spring will break tomorrow. They do mean a tune-up is a good idea, so the replacement can be planned instead of becoming an emergency on a cold morning.

Do not try to fix a torsion spring yourself

Also avoid using the opener to force a door with a broken spring. The opener is not built to lift the full weight. You can strip its gears, bend the top section of the door, or pull the opener rail off the ceiling. Unplug the opener if the door is stuck closed, and leave the door where it is if it is stuck open.

What a proper spring replacement includes

1. Measure the old springs and the door

   Wire size, inside diameter and length are matched to the door weight and height. A good technician weighs or balances the door rather than guessing.

2. Unwind and remove safely

   The remaining tension is released with proper winding bars, then the old spring, and often the cones and center bearing, come off the shaft.

3. Install and wind to the correct turns

   New springs are wound to the number of turns the door height requires, then the set screws are tightened against the shaft.

4. Check cables, drums and bearings

   Frayed lift cables and worn drums are common partners of a broken spring. Replacing them at the same visit avoids a second service call.

5. Balance and safety test

   With the opener released, the door should stay put about halfway up. Then the opener force settings and auto-reverse are tested.

What spring replacement usually costs

Prices vary by door size, spring type and how many parts are worn. As a rough guide for the New York area, replacing a pair of standard torsion springs on a residential door is often quoted somewhere around $250 to $500 including labor. Higher-cycle springs, heavy wood doors, and replacing cables and drums at the same time push it higher. A single extension-spring door is often less.

The technician you are connected with gives you their own price before starting. It is reasonable to ask what spring size they are installing, what cycle rating it has, and what warranty comes with the parts and labor. Our spring cost guide explains the price differences in more detail.

Upgrading to high-cycle springs

If you open the garage many times a day, ask about high-cycle springs. They use heavier wire and longer coils, so the same door spreads its load over more steel. They typically cost more up front but can last two to four times as long. For a family that comes and goes through the garage, that often pays for itself by avoiding the next emergency call.
