Short answer
A broken torsion spring typically costs $150 to $350 to replace, and the Carlsbad figure from HomeBlue (2022) is $200 to $330. If the door suddenly feels heavy, won’t lift, or you heard a loud bang, stop using the opener and call a technician. Never try to wind or loosen a spring yourself.
Signs a garage door spring is broken
Garage door spring replacement Carlsbad homeowners call about usually starts the same way. Look for any of these:
- A loud bang from the garage when the spring lets go.
- The door won’t lift, or lifts a few inches and drops, from the button or by hand.
- The opener hums or strains and the door barely moves. Garaga’s troubleshooting chart lists this as a case to check for binding, an obstruction or a broken spring (Garaga). See also our guide to opener repair.
- A visible gap in the coil of a torsion spring above the door.
- The door hangs crooked, or a cable looks slack.
If you see any of these, stop using the opener. Running it against a door it cannot lift can strain the opener, and lifting a heavy door by hand risks injury. If the power is out as well, read our guide to a garage door that won’t open in a power outage.
Torsion springs vs extension springs
| Type | Where it sits | What to know | Published replacement cost |
|---|---|---|---|
| Torsion | On a metal bar above the door opening | Most common on newer residential doors. Twists to store energy. | $150 to $350 (HomeGuide, Oct 2025, via ThePricer) |
| Extension | Along the horizontal tracks on each side | Stretches and contracts. Raynor puts them at about 10,000 cycles. | $120 to $200 (same source) |
Extension spring systems normally include safety cables that contain a spring if it breaks. Ask the technician to confirm they are in place.
Garage door spring replacement Carlsbad cost: what published ranges say
No source publishes a firm Carlsbad price list for springs, so these are the published ranges. Use them to sanity-check a quote, and see the full Carlsbad price guide for every repair type.
| Source | Range | Notes |
|---|---|---|
| HomeAdvisor, Carlsbad (all repairs) | Typical $167 to $356, average $278 | Covers every garage door repair, not only springs |
| HomeAdvisor, national 2025 | Springs $180 to $350 | Part of its repair cost table |
| HomeGuide, Oct 2025 (via ThePricer) | Torsion $150 to $350, extension $120 to $200 | National figures |
| HomeBlue, Carlsbad (Aug 2022) | $200 to $330 replaced; parts only $110 to $160 torsion, $30 to $50 extension | Older, so expect today’s prices to be higher |
| Thumbtack, Carlsbad | Example start prices of $99 and $185 | Start prices are not final prices |
What moves the price: spring type, door size and weight, cycle rating, number of springs, whether cables or rollers are replaced at the same visit, and after-hours calls. Ask for one total that includes parts, labor and any call-out fee, in writing.
How long do garage door springs last?
Springs are rated in cycles, and one cycle is one open plus one close. Raynor says extension springs are typically around 10,000 cycles and torsion springs 15,000 to 20,000, while other sources call a standard torsion spring 10,000. Check the rating on your quote.
| Cycles per day | 10,000-cycle spring | 15,000-cycle spring | 20,000-cycle spring |
|---|---|---|---|
| 2 (730 a year) | 13.7 years | 20.5 years | 27.4 years |
| 4 (1,460 a year) | 6.8 years | 10.3 years | 13.7 years |
| 6 (2,190 a year) | 4.6 years | 6.8 years | 9.1 years |
This is arithmetic from the rating, not a warranty. Rust, cold and an unbalanced door shorten spring life, according to Raynor, and Thumbtack says springs break every three to seven years in practice. Carlsbad’s damp coastal air makes rust a fair thing to ask your technician about.
If your door has two torsion springs, many companies replace both at once because springs of the same age and use wear at a similar rate. Ask the quote to say whether it covers one spring or both.
Why this is not a DIY job
Garage doors are heavy, and the springs and cables are under a lot of tension, according to HomeServe. A mistake can cause serious injury, and the wrong spring size leaves the door unbalanced. Home warranty provider American Home Shield and the repair companies that publish guides all say the same thing: leave springs and cables to a trained technician.
What you can safely do: keep people and cars clear, leave the door as it is, and call.
Questions to ask before you approve the work
- What cycle rating are the springs, and what does the next rating up cost?
- Is the price for one spring or both, including parts, labor and any call-out fee?
- Will you check the cables, rollers and door balance while the door is open?
- What warranty comes on parts and on labor, in writing?
- What is your CSLB license number? Look it up at the contractor board’s license check before work starts.
Garage door spring replacement Carlsbad: your questions
How much does garage door spring replacement Carlsbad CA cost?
Published ranges run about $150 to $350. HomeBlue’s 2022 Carlsbad figure is $200 to $330. The final price depends on spring type, door size, cycle rating and whether other parts are replaced, so get the total in writing.
How long do garage door springs last?
A spring rated for 10,000 cycles lasts about 6.8 years at four open-and-close cycles a day. Thumbtack says springs commonly break every three to seven years, and rust and cold can shorten that.
Can I replace a garage door spring myself?
It is not recommended. Springs and cables are under a lot of tension and a mistake can cause serious injury. Leave spring work to a trained technician.
Does a home warranty cover a broken spring?
Some do. American Home Shield says its coverage includes torsion springs and the opener but not the door or tracks, and its own pages differ on extension springs, so read your contract.
Is a broken spring an emergency?
Treat it as urgent. The door cannot be lifted safely, and a stuck door can trap a car or leave the garage open. Stop using the opener and call.
Should I replace one spring or both?
On a door with two torsion springs, many companies replace both because they wear at a similar rate. Ask the quote to say which it covers.
