Garage Door Spring Repair

Your garage door is one of the hardest-working systems in your home. Most homeowners open and close their garage door several times a day without giving it much thought—until one morning it refuses to open. In many cases, the culprit is a broken garage door spring.

Garage door springs are designed to do the heavy lifting. They counterbalance the weight of the door, allowing it to open and close smoothly with minimal effort. When a spring breaks, the door can become extremely heavy, difficult to operate, and even dangerous.

If you live in North Idaho, where freezing winters, moisture, and changing temperatures put extra stress on garage door components, understanding the warning signs of a failing spring can help you avoid unexpected breakdowns and costly repairs.

Most residential garage doors weigh anywhere from 150 to over 300 pounds. The garage door opener isn’t designed to lift all of that weight by itself. Instead, the springs carry most of the load.

There are two common types of springs:

Torsion Springs
Mounted above the garage door opening, torsion springs provide smooth, controlled lifting and are found on most modern garage doors.

Extension Springs
Mounted along the horizontal tracks, extension springs stretch and contract as the door moves. These are more common on older garage door systems.

Both types eventually wear out after thousands of opening and closing cycles.

One of the most obvious signs is a garage door that won’t open at all.

You may hear the opener running, but the door barely moves—or doesn’t move at all. Because the spring is no longer supporting the door’s weight, the opener often isn’t strong enough to lift it.

Many homeowners describe the sound of a broken spring as a gunshot or firecracker inside the garage.

When a torsion spring snaps, the stored tension is released instantly, creating a loud noise that can be startling.

If you hear this sound and your garage door suddenly stops working, a broken spring is the likely cause.

If you disconnect the opener and attempt to lift the door manually, it should feel relatively balanced.

If the door suddenly feels like it weighs hundreds of pounds, the spring is no longer doing its job.

Never continue forcing a heavy door open, as this can damage your opener or cause injury.

A torsion spring should appear as one continuous coil.

If you notice a gap of two inches or more in the spring, it has broken and must be replaced.

This is one of the easiest ways to visually confirm the problem.

If only one spring breaks on a two-spring system, the garage door may lift unevenly or appear crooked.

Continuing to operate the door in this condition can damage the tracks, rollers, and cables.

Garage door springs wear out over time, but several factors can shorten their lifespan.

Most residential springs are rated for approximately 10,000 opening and closing cycles.

For an average family, that usually translates to seven to ten years of normal use.

Our climate can be tough on garage doors.

Cold temperatures cause metal to contract, while moisture can lead to corrosion and rust. Over time, these conditions weaken the steel, making springs more susceptible to failure.

Regular lubrication can help reduce rust and extend the life of your springs.

Garage door systems should be inspected and lubricated at least once a year.

Ignoring maintenance allows rust, worn bearings, and excessive friction to place additional strain on the springs.

Garage door spring replacement is not considered a DIY repair.

Both torsion and extension springs are under tremendous tension. Improper handling can cause serious injuries or extensive property damage.

Professional technicians use specialized winding bars and safety equipment to safely remove and install springs while properly balancing the garage door.

Attempting this repair without the proper tools and training is never recommended.

If your garage door has two torsion springs and one breaks, it’s usually best to replace both.

Since both springs have performed the same number of cycles, the second spring is often close to failure.

Replacing both springs at the same time helps:

While springs eventually wear out, routine maintenance can help maximize their lifespan.

Homeowners should:

Preventative maintenance is far less expensive than dealing with an unexpected garage door failure.
