The short answer
Replacing a broken garage door spring typically runs $150 to $350 for a single torsion spring, or $250 to $600 if both springs are replaced as a pair (which most technicians recommend even if only one broke). Extension spring replacement tends to land a bit lower, around $120 to $300 for a pair. These are national ranges that include parts and labor, not a quote for any specific home, and your actual number will depend on the factors below.
Why spring replacement costs what it does
A spring job looks simple from the driveway — pull the old spring, wind in the new one — but the price swings on a handful of real variables.
Spring type: torsion vs. extension
Torsion springs sit above the door on a shaft and are generally safer and longer-lasting, but they require a calibrated winding process and the right tools, which shows up in labor cost. Extension springs run along the horizontal tracks and are often cheaper to source, but if yours don't have safety cables threaded through them, adding those cables is a worthwhile line item on the quote.
One spring or two
If a door has two torsion springs and one just broke, the other is usually close behind it in wear. Many companies replace both at once so you're not paying another service call fee in a few months. It costs more up front but less over the life of the door.
Door weight and size
A heavier door — double-wide, insulated steel, or anything with a lot of glass or decorative hardware — needs a stronger spring to lift it safely. Heavier doors generally mean a higher-rated spring and sometimes a higher price point than a standard single-car steel door.
Spring quality and cycle life
Springs are rated by cycle life — how many times they can open and close before wearing out. Standard springs are typically rated around 10,000 cycles; high-cycle springs (20,000 to 30,000+) cost more but last considerably longer, which can matter in a climate where heat and humidity already stress moving parts.
Local climate factors that affect spring choice
Putnam County's combination of heat, humidity, and salt-tinged air closer to the coast accelerates corrosion on standard-finish springs. Oil-tempered or galvanized springs resist rust better than bare steel and are worth asking about, especially if the garage isn't fully sealed from outside air. Homes built or updated to meet wind-load requirements for hurricane season may also have reinforced doors and tracks, which can mean heavier-duty springs are already in place — and should be matched like-for-like during replacement rather than swapped for a lighter-duty version.
Related repairs discovered on the job
A broken spring often reveals other wear: frayed cables, worn cable drums, or bearing plates that have seized from rust. Replacing these at the same time avoids a second service call, but it does add to the total. A good technician will show you what's worn before replacing it, not after.
Emergency or same-day service
A spring that breaks on a Saturday afternoon, trapping a car inside or leaving the door stuck half-open, often carries an added trip or emergency fee compared to a scheduled weekday appointment.
What a trustworthy quote should include
- The exact spring type, size, and cycle rating being installed
- Whether one spring or both are being replaced, and why
- Any cables, drums, bearings, or rollers included in the price
- Labor and service call fee broken out separately from parts
- A written warranty period on both parts and labor
- A balance and force check on the opener once the new spring is in, since an unbalanced door strains the opener motor
If a quote is just one lump number with no breakdown, ask for the itemized version before agreeing to the work.
