Four fields. A person follows up by phone. If the door is open or hanging crooked, call instead of waiting on the form.

What the visit covers

  • Identify torsion versus extension and whether the door has one spring or a pair
  • Replace a matched torsion pair, or both extension springs with safety cables
  • Check cables, drums, and bottom fixtures while the spring is off
  • Balance the door and only then reconnect the opener

Most “the door won’t open” calls are a spring. Torsion springs sit on the bar above the door. Extension springs run along the horizontal tracks. The repair is different, and so is the typical range.

A torsion spring fails with a bang that people hear in the kitchen. The door may drop a few inches or sit crooked. On a two-car door there are usually two springs on that bar, wound to share the weight. When one breaks, the other is the same age. Replacing only the broken spring leaves a tired partner doing more than its share, and the new spring wears out early. The standard residential job here is a matched pair, sized to the door’s height and weight, then a balance check so the door stays put when it is halfway up.

Extension springs are the long springs beside the tracks, still common on older single-car doors in downtown Murfreesboro, Florence, Christiana, and the earlier houses in La Vergne. They should have a safety cable through the center so a break does not throw the spring across the garage. A lot of the older doors we get called about never had that cable, or the cable is rusted through. The repair is both springs and new cables, then a check that the door is not being dragged by the opener.

Cycle life is why the price band is wide. A standard residential spring is often rated around 10,000 cycles. A household that goes in and out four times a day can use that up in roughly seven years. High-cycle springs (25,000 and up) cost more and make sense on a busy family door in Blackman or Siegel, or on a shop door that opens all day. Wire size and winding are matched to the door on site. This page does not publish winding turns or bar sizes. A torsion spring under tension can cause serious injury, and the cones are not a homeowner adjustment.

Leave the door alone after the bang

If a spring just broke, do not pull the red emergency cord and try to lift the door by hand. Without the spring, a two-car door can weigh well over a hundred pounds, and it can fall. Unplug the opener if it is still trying to drag the door, keep people out from under the panels, and call. A photo of the spring bar, texted to the same number, tells us whether we are looking at a torsion pair or extension springs before the drive.

Typical range for this job

These are typical planning ranges for residential work in Middle Tennessee, compiled so you can tell a spring job from a new-door job before you call. They are not a quote, a coupon, or a list of this company’s set prices. The estimate you get by phone or from the form is based on the door, the parts, and the trip to your ZIP code.

JobTypical rangeWhat moves it
Torsion spring replacement $250–$550 A matched pair on a standard two-car door. One spring, a high-cycle spring, or a heavier door moves the number.
Extension spring replacement $180–$400 Common on an older single-car door. The usual scope is both springs plus safety cables.

Questions about spring repair

Should both torsion springs be replaced?

On a door with two torsion springs, yes. They were installed together and have the same cycles on them. A new spring paired with a tired one carries more than its share of the door.

How do I tell a torsion spring from an extension spring?

A torsion spring is on the shaft directly above the closed door. Extension springs are stretched along the horizontal tracks on each side. The parts, the safety hardware, and the typical range are different.

The opener still lifts the door a little. Can I keep using it today?

That is the opener dragging dead weight, or one remaining spring doing a two-spring job. It burns the opener motor and the door can drop. Leave it until the spring is replaced and the door is balanced.
