Broken spring replacement means fitting a new torsion or extension spring to a residential garage door in Littleton, CO, matching it to the door's weight, then rebalancing the door and testing the opener before we leave. Most calls are finished in one visit, so you get a working door the same day, not a temporary patch.

What this job is

What actually happens when a spring breaks

A snapped spring is one of the more dramatic garage door failures. It usually announces itself with a loud bang from the garage, and after that the door will not lift under its own power.

A garage door is a counterweight machine, and the spring, not the opener, does the lifting. Wound to tension it holds a heavy steel panel in balance, so the motor only has to nudge it along the track. When the coil splits, that stored force is gone, and every pound of the panel lands on whatever tries to move it next, which is usually the opener or your back.

We carry the common spring sizes on the van, which is why most calls are finished in a single visit. On a two-spring door we replace both springs together, because the second one has carried the same number of open and close cycles and normally fails within months of the first.

Once the new spring is on the shaft it gets wound to the number of turns the door's height and weight call for, then checked the way the trade checks it: raise the panel to waist height and let go. A door in balance stays where it was put. A door that creeps up or drifts down gets another quarter turn until it does.

The price covers the new springs, the labor, and rebalancing the door afterward so the opener motor is not left carrying weight it was never built to lift.

Torsion springs mounted above the door and extension springs running along the horizontal tracks wear out the same way: they are rated for a set number of open and close cycles, and age announces itself suddenly rather than gradually. Because the springs hold the full weight of the door under high tension, this is not a repair to attempt without the right bars and clamps.

One number, set before we arrive

It is priced as one job: the springs, the labor and the rebalancing that follows. What can move the figure is listed below.

Before you book

What affects the price?

Door weight and height change how much spring is needed. Whether the door runs on one spring or two changes the parts on the van.

Weight is the biggest lever of the three. An insulated steel double asks for a heavier gauge of wire than a light single panel, and a taller opening needs more turns, which means more wire again.

The cycle life you choose, 10,000 or 25,000 cycles, is another factor, and so is whether the cables and rollers are worn enough to need replacing at the same time.

Cycle life is the one decision you make on the day. One open and one close counts as a cycle, so a household that runs the door four times a day works through roughly 1,460 of them a year. The longer-life spring costs more up front and earns it back on the door a family uses instead of the front door.

The condition of the rest of the hardware settles the last of it. Cables fray where they wrap the drum and rollers wear flat on the stems, and when either is close to done it is far easier to swap while the door is already unloaded and the tension is off the shaft.

Questions

Frequently asked questions

Can I still open the door by hand?

Usually not, and you should not try. The spring carries the weight of the door, so with it broken the door is 150 to 250 pounds of dead weight.

Do you replace both springs?

On a two-spring door, yes. The second spring has the same cycles on it and normally breaks within months, and a second call-out costs more than the spring.

How long does the visit take?

About two hours for a standard double door, including rebalancing and testing the opener.

Is my opener damaged too?

Sometimes. An opener that has been lifting an unbalanced door strips its gear over time, and we test it before we leave so you know either way.
