Garage Door Spring Repair in Killeen

If you heard a loud bang from the garage of your Killeen home and now the door barely moves, or the opener strains and stops after a few inches, a broken spring is the most likely cause. Springs carry almost all of the door's weight, so when one fails the door becomes too heavy for the opener or for you to lift. Leave the door where it is and have a local pro replace the spring. This is not a safe do-it-yourself job.

How garage door springs work

A garage door is balanced, not lifted. The springs store enough energy to offset the door's weight, so a working opener only has to nudge it. Residential doors use one of two systems:

• Torsion springs sit on a steel bar above the door opening. They wind up as the door closes and unwind to help lift it. Cables run from drums at each end of the bar down to the bottom corners of the door.
• Extension springs run along the horizontal tracks on each side, stretching as the door closes. Each one should have a safety cable running through its center so a broken spring cannot whip across the garage.

The Door and Access Systems Manufacturers Association (DASMA) says spring systems "should be repaired only by trained professionals," and that a door with extension springs but no safety cables deserves a safety inspection. Springs and their cables hold enough stored energy to cause serious injury, which is why this page gives warning signs and quote advice but no repair steps.

Warning signs of a worn or broken spring

• A gap of a few inches in the coiled torsion spring above the door. That gap is the break.
• The door feels very heavy when you lift it by hand, or slams down when lowered.
• The opener hums, lifts the door a few inches, then stops or reverses.
• The door rises crooked, with one side higher than the other.
• One extension spring looks stretched out compared with the other.
• Loud snapping, or a door that worked yesterday and will not move today.

What to do before the pro arrives

Keep everyone, especially children and pets, out from under the door. Do not keep pressing the remote; the opener can strip gears or pull the door out of its track trying to lift dead weight. Chamberlain's opener manuals warn that weak or broken springs can make an open door fall "rapidly and/or unexpectedly," and say to pull the emergency release only when the door is closed if possible. If the door is stuck open with a broken spring, leave the release alone and tell the contractor the door's position when you ask for help.

What a good spring quote lists

A clear written quote for spring work should name:

• Spring type and count. Torsion or extension, and how many. DASMA advises that if your door has two springs, both should be replaced even if only one broke, because the survivor has seen the same wear.
• Spring size. Wire gauge, inside diameter and length. Springs are sized to the door's weight and height, so the pro should weigh or measure rather than guess.
• Cycle rating. One cycle is one full open and close. Standard springs carry a lower rating and higher-cycle springs cost more but last longer. Ask what rating is quoted. At four cycles a day, a household uses about 1,460 cycles a year, so the rating translates directly into years.
• Related parts. Whether cables, drums, center and end bearings, or rollers are being replaced, and whether each item is required or optional.
• Balance and safety checks. The door should be balanced after the new springs go on, and the opener's force and reversing settings checked.

What spring repair costs

This Old House's 2026 cost guide, drawing on Homewyse data, puts spring replacement at about $300 to $540 nationally including parts and professional labor, with an average near $420. It lists installed extension springs at roughly $300 to $400 and torsion springs at roughly $350 to $540. Those are national averages, not Killeen prices. The local total depends on:

• torsion or extension, and one spring or a pair;
• the size and weight of the door (a heavy wood or insulated double door needs larger springs);
• the cycle rating you choose;
• whether worn cables, drums or rollers are replaced at the same visit;
• any trip or diagnostic fee.

Ask for the total before work starts. Our repair cost guide has a checklist for comparing two estimates side by side.

How long springs last

The same This Old House guide puts torsion springs at about 8 to 15 years and extension springs at about 7 to 12 years, depending on use. A door used as the family's main entrance wears through its springs far faster than one opened twice a day. If your springs are original to a house built more than a decade ago, it is worth asking the pro to check them during any other repair.

When the cables are damaged too

A spring break often frays or unspools the lift cables. If a cable is hanging loose or the bottom of the door sits unevenly, mention it in your request. See track and cable repair for how those repairs are quoted.

Common questions

Can I open my garage door with a broken spring?

Avoid it. Without the spring the door's full weight is on the opener or on you, and it can drop suddenly. Wait for a pro, or ask the contractor how to get a vehicle out safely.

Should both springs be replaced if only one broke?

Usually yes. DASMA recommends replacing both springs on a two-spring door, because the remaining spring is the same age and likely close to failing.

How much does garage door spring repair cost?

This Old House's 2026 guide puts it at about $300 to $540 nationally with parts and labor. Your quote depends on spring type, door weight and whether other parts need work.

What is a high-cycle spring?

A spring built to survive more open-and-close cycles than a standard one. It costs more up front and is worth asking about if your door is used many times a day.
