The Short Answer
Nationally, garage door spring replacement typically runs $150 to $350 for a single torsion spring, and $250 to $450 if both springs are replaced at the same time, which most reputable technicians recommend since springs wear out in pairs even if only one has broken. Extension spring replacement tends to run a bit less, often $120 to $300. These are national ranges, not a local price, and your actual number depends on the factors below. Any quote you get should spell out which type of spring you're buying, how many, and why.
Torsion vs. Extension: Why It Matters for Price
Most garage doors built in the last couple of decades use torsion springs mounted on a shaft above the door, while older doors often use extension springs that stretch along the horizontal tracks on each side. Torsion springs cost more per unit because they're wound to a precise tension and require the right bar and gauge for your door's weight, but they last longer and are safer to service when done correctly. Extension springs are cheaper individually but are usually sold and installed as a pair, and older setups may need safety cables added if they're missing, which adds a modest amount to the job.
What Pushes the Price Up
- Door weight and size. A heavier insulated door, or a wide double-car door, needs a higher-cycle or higher-gauge spring, which costs more than the springs on a lightweight single-car door.
- Number of springs. Replacing both springs together costs more upfront than fixing just the broken one, but it avoids paying for a second service call a few months later when the other spring gives out.
- High-cycle springs. Standard springs are rated for roughly 10,000 cycles; high-cycle versions rated for 20,000 to 25,000+ cost more but mean fewer replacements over the life of the door, which can be worth it if you use the garage door several times a day.
- Emergency or after-hours service. A spring that snaps on a Sunday evening or during a snowstorm often comes with a premium for same-day or off-hours work, which is reasonable given the technician is coming out immediately rather than scheduling you for later in the week.
- Hardware condition. If the cable drums, bearing plates, or center bracket are worn, rusted, or damaged from the spring failure, those parts may need replacing too, and that's separate from the spring cost itself.
- Opener strain. If the spring has been weak or broken for a while and the opener has been straining to lift the door, the drive gear or motor may also need attention, which a good technician will check and flag rather than just swapping the spring and moving on.
What Can Keep the Price Down
- Catching it early. A spring that's stretched, sagging, or making a grinding noise but hasn't snapped yet is a planned repair, not an emergency, so you can schedule it during normal hours.
- Standard-size, lighter doors. A single-car door on a standard spring doesn't need the heavier-duty components a wide insulated door requires.
- Routine maintenance. Springs that are lubricated and inspected periodically tend to fail less abruptly and give you more warning before they go.
Why Winter and Spring Thaw Matter Here
Cold temperatures make steel springs more brittle and more likely to snap, and that risk goes up when a door has been sitting through months of deep cold, road salt tracked in on tires, and the grit and moisture of spring thaw. Salt and moisture accelerate corrosion on springs, cables, and hardware, so a spring that looks fine in August can be the one that lets go in January. If your spring is already showing rust, gaps between the coils, or visible stretching, it's worth having it looked at before winter sets in rather than after it fails on a sub-zero morning.
What a Trustworthy Quote Should Include
Before you agree to any spring replacement, the quote or invoice should clearly list:
- The type and size of spring being installed, including wire gauge and cycle rating
- Whether one or both springs are being replaced
- Labor as a separate line item from parts
- Any additional hardware being replaced, such as cable drums, bearings, or safety cables, and why
- Whether the opener or track was inspected as part of the job, and what was found
- A warranty on both the parts and the labor, in writing
If a quote is vague about which spring is going in or skips the warranty altogether, ask before you sign off. A clear, itemized quote protects you either way, whether the job turns out to be simple or more involved once the technician is under the door.
