The opening comes first
A single, a double, an RV bay, and a commercial opening are four different jobs. Your opening size sets the sections, the spring, the track, the operator, the labor, and what it costs to take the old one away — which is why the first question you should get asked is how wide it is.
Finish choices change the number
Raised-panel steel, insulation, full-view glass, wood tones, decorative hardware, and custom window layouts are all legitimate and all optional. Ask for them as separate lines. If they arrive bundled into one figure you cannot see what the door needed and what you chose, and you will overspend on the half that does not show.

Repair cost depends on safety and parts
Get the door made safe before anyone prices the repair — a door that cannot be moved safely cannot be assessed. Then ask what the repair buys you in years. Once repairs start stacking up on an aging door, the arithmetic usually turns, and you want to see that arithmetic rather than be told it.
Commercial doors need downtime math
Work out what an hour of that bay being down costs you before you compare anything. Then check that each quote covers access, duty cycle, operator type, safety devices, and your business hours. A quote missing those is not cheaper; it is just less finished.
