You hear it before you see it: a loud bang from the garage, like a car backfired inside the house. Now the door won't budge, or it opens a few inches and stalls, or one side hangs lower than the other. You pull the cord to check, and there it is — a torsion spring split clean in two above the door, or a stretched extension spring dangling loose along the track. The moment you spot it, the next question is obvious: what is this going to cost?
What Garage Door Spring Replacement Typically Costs
These are national ranges, not quotes for any specific home — your actual price depends on the factors below and what a local technician finds once the door is open.
- Single torsion spring replacement: roughly $150–$350 including parts and labor
- Double torsion spring set: roughly $250–$450
- Extension springs (pair): roughly $100–$300
- High-cycle or heavy-duty springs for larger or heavier doors: add $50–$150 to the above
- Emergency or same-day service: often adds $75–$150
- Related hardware found worn during the job (cables, rollers, center bearing): $50–$200 per item
If only one spring broke, many technicians will recommend replacing both at the same time. Springs are rated for a certain number of open-close cycles, and if one failed from age or wear, the matching spring is usually close behind. Replacing both now costs more upfront but avoids a second breakdown — and a second service call — a few months later.
Factors That Push the Price Up or Down
Spring Type and Count
Torsion springs mount on a shaft above the door and are generally more durable and safer to operate than extension springs, which stretch along the horizontal tracks. Torsion setups often cost more per spring but last longer under regular use. Doors with two torsion springs cost more to service than single-spring setups simply because there's more hardware involved.
Door Weight and Size
A single-car door and a double-wide door don't use the same spring. Heavier doors — insulated steel, carriage-style with hardware, or oversized two-car doors — need springs rated for more weight and more cycles, which costs more than the springs on a lightweight single door.
Wind-Load and Reinforcement
Doors built to meet wind-load requirements for storm-prone areas often carry reinforced struts and heavier panels to resist pressure during high winds. That added weight calls for correctly matched spring tension — using an undersized spring on a reinforced door strains the opener and shortens the spring's life. If your door was upgraded or reinforced for hurricane season, mention that when you call for a quote.
Climate-Related Wear
Humidity and afternoon storms take a toll on exposed metal hardware. Torsion springs that sit in a garage with poor ventilation can develop surface rust faster than springs in a dry, climate-controlled space, which shortens their working life and sometimes causes a spring to bind or snap before the cycle count was reached. Rust and swelling from moisture also affects cables, rollers, and track alignment, so a spring failure is a reasonable time to have those checked too — and that inspection sometimes turns up additional small repairs that affect the final bill.
Access and Timing
A door that's easy to reach, in a garage with clear working space, costs less to service than one with obstructions, low clearance, or an opener mounted in a tight spot. Calling for same-day or after-hours service because the door is stuck shut with a car trapped inside will also run higher than a scheduled daytime appointment.
What a Real Quote Should Include
- A diagnostic visit or service call fee, stated upfront
- The specific spring type, size, and cycle rating being installed — not just "a spring"
- Labor separate from parts, so you can see what you're paying for
- A check of cables, rollers, and the center bearing, since these wear alongside springs
- Any warranty terms on parts and labor, in writing
- No surprise charges for anything found mid-repair without your approval first
If a quote is just one lump number with no breakdown, ask for the details before work starts. A spring that's correctly sized and properly balanced to the door's weight will last years; one installed quickly without checking the rest of the hardware can fail again sooner than it should.
When to Call Wellborn Garage Door Pro
If a spring has already snapped, don't try to force the door open — the tension involved makes this one of the few garage door repairs that's genuinely dangerous to handle yourself. Call for Garage Door Spring Repair and we'll inspect both springs, the cables, and the drums before quoting anything, so you know exactly what's being replaced and why. If your springs are still intact but the door feels harder to lift than it used to, or makes a grinding or popping sound partway through its cycle, that's worth catching during a Garage Door Maintenance & Tune-Up before it turns into an emergency call during a storm.
