Randolph prices generally track the rest of northern New Jersey, but a few local factors move the number. Heavy insulated doubles on newer colonials need bigger springs and more labor than a single door on an older ranch. Tuck under garages with low headroom can require special track kits. Doors that froze to the slab and were forced with the opener often need cables or a gear on top of the original repair. Calls on the coldest mornings, when many springs break at once, can also mean evening or emergency rates.
| Job | Typical range | What moves the price |
|---|---|---|
| Torsion spring replacement (pair, installed) | $250 to $500 | Door weight, spring size, high cycle upgrades, and whether one or two springs are replaced |
| Extension spring replacement (pair, installed) | $150 to $350 | Door size and whether safety cables need to be added or replaced |
| Off-track or cable repair | $150 to $450 | Whether track sections, rollers, or cables need replacing and how badly the door is jammed |
| Opener repair | $125 to $350 | Simple sensor or settings fix versus a gear, trolley, or logic board replacement |
| New opener, installed | $400 to $900 | Chain versus belt drive, horsepower, battery backup, and smart features |
| Tune-up and maintenance visit | $100 to $250 | What is included and whether rollers or weatherstripping are replaced |
| Single panel replacement | $300 to $1,000 | Whether a matching panel is still made for your door model |
| New garage door, installed | $1,000 to $5,000 or more | Single versus double width, insulation, material, windows, and custom styling |
These are typical ranges only; your actual price depends on your door and the contractor's quote after seeing the job.
