Spring replacement
The biggest variables are spring type and size. A standard residential torsion spring is not the same job as a high-cycle pair on a heavy insulated door. If both springs are original, replacing the pair costs less than doing them one at a time six months apart.
Cable replacement
Usually one of the cheaper repairs, but the price depends on what else happened when it snapped. If the door came off the track or the drum got damaged, that adds to it.
Opener repair versus replacement
A gear kit or a logic board is a fraction of the cost of a new unit. Replacement makes sense when the opener is old enough that parts are scarce, or when you want the safety and security features a modern unit brings.
Roller and hinge replacement
Inexpensive individually, and best done as a set while the technician already has the door open. Nylon rollers are worth the small upgrade.
Panel replacement versus a new door
One damaged section on a recent door is usually worth replacing. On an older door, matching a discontinued panel profile and color can cost more than it is worth, and a new door is the better call.
New garage door installation
Driven by size, material, insulation value and whether the opening needs new track and hardware. An uninsulated steel single door and a custom insulated carriage-style double are very different projects.
What should never be in the price
Vague line items, a call-out fee stacked on top of an approved repair, or a number that grows once the technician is in your driveway. Get the figure before work starts.
