What happens when a garage door spring breaks?

A garage door spring does the heavy lifting. A typical two-car steel door weighs well over a hundred pounds, and the springs carry nearly all of that weight so the opener only has to guide the door along its track. When a spring snaps, the weight lands on the opener and on your arms. Many people describe a loud bang from the garage, like something heavy was dropped. Others only notice later, when the door will not lift or the opener hums and the door barely moves.

If you think a spring has gone, stop using the door. Do not keep pressing the wall button, and do not try to force the door up by hand. If the door is stuck open, keep cars and children clear of the opening and call a technician. A door that is partly lifted can drop without warning.

Why should I not replace a garage door spring myself?

Torsion springs are wound under very high tension, and the winding is done with steel bars in small, careful steps. If a bar slips or a set screw lets go, the spring unwinds in a split second. That can cause broken bones and worse. Extension springs are not safer, because a broken one can whip across the garage.

There is a second problem. The right spring depends on the door's weight, height and drum size. A part from a shelf may look right and still be wrong, which leaves the door too heavy or too light and wears out the opener. No online video makes this a safe weekend project, and we do not give do-it-yourself steps for it.

What a technician checks

  • The door's actual weight and height
  • The spring size, type and cycle rating
  • Cables, drums, bearings and rollers
  • The balance of the door after the new spring is set

Why do springs fail in St. Louis garages?

Every spring wears out. It is rated for a set number of cycles, and each trip up and down uses one. In a home where the garage door is the main way in and out, such as a detached alley garage in south city, those cycles add up faster than people expect.

The climate speeds things along. Humid summers put a film of rust on the coils, and rust roughens the steel and weakens it. Winter freezes stiffen old lubricant, and a tired spring often gives out on a cold morning because that is when the door gets used. Many older brick bungalows still have the original extension springs on both sides of the door, and those have been working for a long time.

A spring that fails can also damage nearby parts. A snapped spring often leaves a frayed cable or a door that sits crooked. Our cable and track repair page covers what happens next if that is the case.

We quote in writing before work starts, and the price depends on the door and the parts it needs. The main factors are listed here.

  • Door size and weight, which set the spring size
  • Torsion springs or extension springs
  • One spring or a pair on the same door
  • A higher cycle rating, if you use the door often
  • Other worn parts found during the visit, such as cables or rollers
  • Access, since a cramped detached garage can take longer to work in

Springs on the same door are usually the same age, so technicians often suggest replacing both even when only one has broken. Ask for the reasoning and the difference on the quote. If a worn cable or roller turns up, you will see it on the quote and can say yes or no.

How long does it take, and what to expect on the day?

Many spring jobs are finished in a single visit when the technician arrives with the right springs. An unusual size or an older door may need a part ordered, and the crew will tell you if that is the case.

On the day, the technician looks at the door, secures it so it cannot move, removes the broken spring, installs the matched one, and sets the tension. Then they lift the door by hand to check the balance, run it through the opener, and lubricate the moving parts.

You can help by clearing space around the door, moving cars out of the garage, and keeping pets inside. Mention any rubbing sounds or dents, since they affect how the door moves.

When should I call?

Call when you see a gap in the coil of a torsion spring, when the door feels heavy or will not stay halfway up, when it sits crooked, or after you hear a loud bang from the garage. Call if the opener strains or the door closes faster than it should.

If you want a second look at the opener afterward, see our garage door opener repair page, or return to the home page for the other services we offer. Call (314) 555-0112 and describe what you see, and we will tell you what the next step should be.

Questions about garage doors in St. Louis

How do I know a garage door spring has broken?

Common signs include a loud bang, a door that is very heavy to lift, a door that will not open more than a few inches, and an opener that hums without moving. On a torsion spring, you may see a visible gap in the coil above the door. Stop using the door and call a technician.

Should I replace one spring or both?

If your door has two springs, technicians often suggest replacing both. They have done the same number of cycles and the second one is likely to fail soon. Replacing both also keeps the door balanced. Your quote can show the cost of both options so you can decide.

Can the opener lift the door with a broken spring?

It may try, but it should not. Openers are built to guide a balanced door, not lift its full weight. Running the opener against a broken spring can strip gears and burn out the motor, turning a spring repair into a spring and opener repair. Stop using the door until it is fixed.

Why do springs seem to break on cold mornings?

A worn spring is under stress every time the door moves. Cold stiffens the lubricant and makes the metal less forgiving, and the first use of the day is often when the weakest spring finally gives way. The cold did not cause the wear, but it can be the last push.

How long will a new spring last?

That depends on the cycle rating of the spring and how often you use the door. A family that uses it several times a day wears it out faster than one that uses it once. If you use your garage heavily, ask about springs with a higher cycle rating and what that changes on the quote.

Do I need to be home for the repair?

Someone should be there to let the technician into the garage, confirm the quote, and check the door afterward. If your garage is detached and the opener is off, tell us how to get in. We will discuss access when you call.
