Torsion vs. Extension Garage Door Springs: Differences, Cost, and Safety

Don't touch a broken spring, and don't release the opener on an open door. Both spring types store a lot of force. If you heard a bang or see a gap or a stretched spring, leave the door alone and request help. See is it safe to open a garage door with a broken spring?

Knowing which spring your door uses helps you read a quote and understand what's broken. It does not mean you should work on it. Here's the difference, in plain terms.

How to tell which spring you have

Torsion spring Extension spring
Where it is On a metal bar above the closed door Along each side of the door, beside the horizontal track
How it works Twists to counterbalance the door Stretches and contracts as the door moves
What a break looks like A visible gap in the coil, often with a loud bang A stretched or hanging spring on one side
Cost per spring (Angi, Minneapolis) $80–$160 $50–$110

Angi notes that both types are common on sectional doors, tilt-up (one-piece) doors use extension springs, and roll-up doors use torsion springs.

Which is better?

Angi's Minneapolis guide says torsion springs have longer lifespans and are generally considered safer, and that extension springs are cheaper. That's the tradeoff: lower price now, or a longer-lasting system. If you're replacing a broken extension spring, ask the company whether your door is a good candidate for torsion, and what the conversion would cost.

Angi's Minneapolis spring page lists its overall average inconsistently, so we cite only the ranges it states clearly. For our own cost guide, see spring replacement cost. The company you're connected with sets its own price.

Why both springs get replaced together

Angi says that when one spring on a door fails, it's better to replace both so the door stays balanced. Ask for the price of one spring and of both.

Questions to ask about a spring quote

  1. Is my door torsion or extension, and what are you replacing?
  2. Is the quote for one spring or both?
  3. What cycle rating do the new springs have?
  4. Does the price include checking the cables, rollers, and balance?
  5. What's the warranty on the springs and on labor?

Frequently asked questions

What is the difference between torsion and extension springs?

Torsion springs are mounted on a bar above the door and twist to lift it. Extension springs run along the sides of the door, parallel to the horizontal tracks, and stretch and contract. Angi says torsion springs have longer lifespans and are generally considered safer, while extension springs are cheaper.

How much does it cost to replace each type in Minneapolis?

Angi's Minneapolis spring guide (updated July 9, 2026) lists $50–$110 for an extension spring and $80–$160 for a torsion spring, per spring. A full single-door job, including labor, is listed at $160–$370. Labor is $80–$160 for a residential door.

Can I switch from extension to torsion springs?

Yes, but it's a bigger job. Angi's Minneapolis guide lists $420–$840 to convert extension to torsion and $260–$530 to convert torsion to extension, because the old spring parts have to be removed and a different system installed.

Should I replace both springs when one breaks?

Angi recommends it. When one spring fails, replacing both at the same time keeps the door balanced, and a contractor will likely give a better price when both are done in one visit.

Can I replace a spring myself?

We don't recommend it. Angi says garage door springs are under high tension and that a pro has the tools and experience to do the job safely. See should you replace a spring yourself?.
