Broken Garage Door Spring: What to Do (and What Not to Try)

Quick answer: You can almost always identify a broken garage door spring yourself, there is a visible gap in the coil, the door feels twice as heavy, and the opener strains or refuses to lift. You should not try to replace it yourself. A loaded torsion bar stores 6 to 9 turns of energy and can break a wrist or fracture a skull when it unwinds wrong. Same-day repair in Houston usually runs $240 to $440 depending on whether you replace one spring or the matched pair. Call us, leave the door alone.

How to tell if your spring is broken

Four signs sort this in under a minute. The gap: look at the spring on the bar above the door. A healthy spring is a tight steel coil; a broken one has a clean two-to-four-inch gap where it separated. The weight: pull the red manual release rope and try to lift the door by hand. A balanced 16-foot door feels like a heavy suitcase; with the spring broken you are lifting the full dead weight, roughly double. The opener: a door opener assists a counterweighted door, it does not deadlift one, with a broken spring the motor hums, strains, stops a few inches up, or trips the safety reverse. The bang: torsion failures make a noise customers describe as a gunshot. If you heard one and now the door will not work, that was the spring.

Why DIY spring replacement is genuinely dangerous

A torsion spring on a residential door is wound to 6 to 9 turns of tension before it ever lifts the door. That stored energy does not disappear when the spring breaks, it stays trapped in the coil and the torsion bar. Replacing one safely requires two properly sized steel winding bars and controlled unwinding. If a bar slips out of the cone, it becomes a 24-inch steel lever flying at the tech's face. The U.S. Consumer Product Safety Commission tracks the recurring injuries from this: broken wrists and forearms, deep facial lacerations, skull fractures. People die from it every year. Every DIY-injury photo we have seen involved a substitute tool, a screwdriver, a piece of rebar, a length of conduit, that bent or sheared at the worst moment.

What NOT to do in the meantime

Do not keep hitting the opener button. The motor was sized for an assisted lift, not a dead lift. Every forced cycle burns motor windings, strips gears, and can pull the rail off the ceiling brackets, we have watched a $290 spring job turn into an $1,100 spring-plus-opener-plus-rail repair because a homeowner cycled the door 15 times before calling. Do not lift the door if the cables look frayed or unspooled. When a spring snaps, the cables briefly take the full load; sometimes they survive, sometimes they jump the drum or part entirely. A compromised cable can drop the door while you are holding it. Do not park inside if the door is stuck open with a suspect cable, that is a several-hundred-pound steel object waiting to fall.

What to do right now

Three steps, in order. One: pull the red manual release rope from the opener trolley to disconnect the door so the motor stops fighting the broken spring. If the door is closed, leave it closed. Two: secure the door. With the spring broken and the opener disconnected, the door will not stay up on its own, if it is open, lower it carefully with two people or wait for the tech. Three: call us. We bring a stocked truck with galvanized oil-tempered springs in every common residential size, so the vast majority of spring jobs are diagnosed and finished in one visit, usually inside 90 minutes.

Why your spring lasted only 5 to 7 years in Houston

The box says 10,000 cycles. The Gulf Coast reality is closer to 7,500. At five cycles a day, 365 days a year, you put roughly 1,800 cycles on the spring annually. A 10,000-cycle spring should last 5 to 6 years at that pace, but Houston is not ideal conditions. An unconditioned attached-garage attic holds 130 degrees through August, and that sustained thermal load fatigues the spring's grain structure faster than the lab tests model. The 10,000-cycle spring effectively becomes a 7,500-cycle spring. That is why we recommend the matched-pair replacement on two-spring doors (the second one lived through the same summers) and the 25,000-cycle Gulf-Coast-rated upgrade for anyone who does not want to do this again in six years.

Frequently asked

How did my spring break if it sounded fine yesterday?

Springs almost never warn you. The steel coil is under constant load, and Houston's heat-humidity cycle quietly fatigues the metal over years. The break is sudden, one last cycle and the coil snaps, usually with a bang that sounds like a gunshot in the garage. If you heard a loud noise and woke to a door that will not open, that bang was the spring letting go. There is no maintenance you missed; it is the nature of a fatigued steel coil at end of life.

Can I just replace the broken spring and leave the other one?

On a two-spring door we strongly recommend replacing both. They were installed the same day, cycled the same number of times, and endured the same Houston summers. The second spring is statistically close to failure, usually within months. Replacing only the broken one means a second service call and another diagnostic fee. A matched pair, $340 to $440 in our area, costs less than two single-spring calls back to back.

Is it safe to back my car out if the spring is broken?

Only if the door is fully closed and you can leave it closed. Do not lift the door manually. With the spring broken, a 16-foot insulated door weighs 280 to 340 pounds of dead lift, and the cables are under abnormal load and can fail without warning. If your car is trapped inside, call us, we get you out safely the same day in most cases.

How fast can you get there?

Same day across Houston, Sugar Land, Katy, The Woodlands, and Pearland in most cases. Broken-spring calls placed before early afternoon usually get a same-day slot. After-hours calls get a 30-minute callback; if your car is trapped or the house is unsecured, we treat it as an emergency and dispatch that evening when we can.

Will a new spring last another 6 to 8 years in Houston?

We install oil-tempered galvanized springs rated for 10,000 cycles, which in Houston's heat drops to roughly 7,500 real-world cycles. A household cycling the door 4 to 6 times a day gets about 5 to 6 years out of that. If you want longer life, the 25,000-cycle Gulf-Coast-rated upgrade is about $50 to $80 per spring and pushes service life into the 13 to 16 year range.
